The Siamang inhabits the forest remnants of Sumatra Island and the Malay Peninsula, and is widely distributed from lowland forest to montane forest, even a rainforest. And can be found at altitudes of up to 3800 m [5]. The Siamang lives in groups of up to 6 individuals (4 individuals on average) with a home range 23 hectares on average.[6][7]. Their day ranges are substantially smaller than those of sympatric Hylobates species, often less than 1 km[8]. The Siamang's melodious choir singing breaks the forest's silence in the early morning after the Agile Gibbon or Lar Gibbon's calls. The Siamang in Sumatra and the Malay Peninsula are similar in appearance, but there are some differences in behaviour between the two populations.
Diet
The Siamang mainly eats various parts of plants. The Sumatran Siamang is more frugivorous than its Malayan cousin, with fruit making up to 60% of its diet. The Siamang eats at least 160 species of plants, from vines to woody plants. Its major food is figs (Ficus spp.), a member of Moraceae family.[7][9] The Siamang prefers to eat ripe fruit rather than unripe fruit, and young leaves rather than old leaves. It eats flowers and a few animals, mostly insects. When the Siamang eats large flowers, it will eat only the corolla (petal), but it will eat all parts of smaller flowers, with the small fruit collected in its hand before being consumed. When it eats big and hard seeds or seeds with sharp edge it will peel out the fruit flesh and throw away the seed.[9] Although its diet consists of substantial portions of fruit, it is the most folivorous of all members of Hylobatidae[10]. As it is also the largest gibbon, and thus fits well with the general primate dietary trend in which larger primates tend to be more folivorous.
Demography and population
A group of Siamang normally consist of an adult dominant male, an adult dominant female, with offspring, infant and sometimes a sub-adult. The sub-adult usually leaves the group after the age 6 to 8 years; sub-adult females tend to leave the group earlier than sub-adult males. Siamang males tend to offer more paternal care than other members of the family Hylobatidae, taking up a major role in carrying the infant after it is about 8 months old [12]. The infant typically returns to its mother to sleep and nurse. A study in relation to effect of habitat disturbance on the Siamang found that group composition is varied in age-sex structure between intact forest and post-burnt forest. The post-burnt population was more adult and sub-adults than the intact population. Post-burnt groups contain fewer infants, small juveniles and large juveniles compared to intact forest groups. Infant survival rates in post-burnt groups are lower than in intact forests. The number of individuals in intact forests is higher than in post-burnt forests.[7] The Siamang in disturbed forests live in small groups and have a density lower than in intact forests because of lack of food resources and trees for living.
In the 1980s, the Indonesian population of the Siamang in the wild was estimated to be 360,000 individuals.[13] This seems over-estimate today, as an example, Bukit Barisan Selatan National Park (BBSNP) is the third largest protected area (3,568 km²) in Sumatra, of which approximately 2,570 km² remains under forest cover inhabit by 22,390 siamangs (in 2002 censuses). According to two different research projects conducted in Sumatra, the Siamang prefer to inhabit lowland forest below between 500 m in altitude and over 1000 m above sea level.
Behavior
The Siamang tends to rest for more than 50% of its waking period (from dawn to dusk), followed by feeding, moving, foraging and social activities. It takes more rest during midday, taking time to groom each other or play. During resting time it usually uses a branch of a large tree lying on their back or on their stomach. Feeding behaviors, foraging, and moving are most often in the morning and after resting time.
In the dry season the length of the Siamang's daily range is longer than in the rainy season. The Siamang in southern Sumatra undertakes less foraging than the Siamang in other places because it eats more fruit and therefore consumes more nutrition, which results in less time needed for looking for food. Sometimes the Siamang will spend all of the day in one big fruiting tree, just moving out when it wants to rest and then coming back again to fruiting trees.
Role of calling
The Siamang starts its day by calling in the early morning and calls less after midday, with the peak of their calls around 9:00 am to 10:00 am. Most of the Siamang's calls are directed to its neighbours rather than to inside its home range. This means that the Siamang's calling is in response to disturbances and is to defend its territory. Calls in the late morning typically happen when it meets or sees another Siamang group. The edge of the Siamang's home range, which may overlap another, is often the places where calling is made. Counter-call (co-response calling) occasionally happens near the border or in the overlap area. Calls are numerous when fruit is more abundant rather than when fruit is less available. Branch shaking, swinging, and moving around the tree crowns accompany the calling. This movement might be to show the other groups where they are.
The Siamang prefers calling in the living, high and big trees, it might be the places where another group is easy to see. Beside that, living, big, and tall trees can support Siamang movement. Calling trees are usually near feeding trees but sometimes they call in the feeding trees.
Siamang and their habitat
As a frugivorous animal, the Siamang disperses seeds through defacation as it travels across its territory. The Siamang can carry seed and defecate over 300 m with the shortest distance being 47.6 m from the seed resource, which supports the forest regeneration and succession.
Threats to population
The Siamang, as an arboreal primate, absolutely depends on the forest for existence, needing trees for its living. At the moment, the Siamang is facing a population decrease due to habitat loss[6], poaching and hunting.
Habitat loss
A major threat to the Siamang is habitat loss due to plantation, forest fire, illegal logging, encroachment, and human development. Firstly, palm oil plantations have removed large areas of the Siamang's habitat in the last four decades. Since 2002 107,000 square kilometres of palm oil have been planted,[17] which has replaced much rainforest in Indonesia and Malaysia, where the Siamang originally used to live. Secondly, in the last two decades, forest fire destroyed more than 20,000 km² of Sumatran rainforest, mainly in the lowland area where most of the Siamang live. Thirdly, the rate of illegal logging in Indonesia increased from 1980 to 1995 and even more rapidly after the reformation era beginning in 1998.[17] These illegal activities devastated the remaining tropical rainforest especially in Sumatra. Fourthly, forest encroachments change forest cover into cultivated land, for example; the rising price of coffee in 1998 has been encouraging people in Sumatra to replace the forest with coffee plantation.[18] Fifthly, development in many areas needs infrastructure such as roads, which now divide a lot of conservation areas have been caused forest fragmentation and edge effects. Unfortunately, the Siamang as an arboreal primate faces difficulty because road establishment has disconnected their pathways.
Poaching and hunting
Unlike other parts of Asia, primates are not hunted for their meat in Indonesia (the exception is in Chinese restaurants in Indonesia which sometimes serve macaque on their menu). However, they are poached and hunted for the illegal pet trade, mostly for infant Siamang. Poachers kill the mothers because mother Siamang are highly protective of their infants. It is therefore very difficult to remove the infant without first killing the mother. Despite the fact that most Siamang on the market are infants many infants nevertheless die during transportation

Why everybody must be blonde?
Today all the girls want to be blonde and blue eyed.
Blame it to the stereotypes of Capitalism and its
famous icon of Barbie Girls like that vulgar singer
called Lady Gaga (if you don´t have noticed yet,
all in her is fake, starting from her fake blue eyes,
and ending to her platinum dyed hair). But there
was a time, in the early 30´s , where all the girls
want to have dark hair, like Betty Boop, a cartoon
character created in 1930 during the great depresion.
Betty was the first sex symbol, and was not made of
flesh and blood hahaha. Many years before Marilyn
Monroe and Rita Hayworth she wore short dresses,
high heels, a garter belt, and a generous neckline :P
Someting very revolutionary for the rancind moral of that
age where all the good girls girls must be at home cleaning
their houses, cooking, taking care of their children and pleasing
their men. That´s the reason I´ve always found Betty very funny
(add this that in the first sketches that Max Fleischer draw
Betty looked like a French poodle :D). Forgot to say that Betty
character was inspired by the "Flapper girls", who loved Jazz music,
short haircuts (garçonne style) and have a rebel behaviour
against men and s society :D
THE MEANING OF LIFE
Just a bit of Philosophy, and
sometimes a little bit of irony.

many thanks for your indiference about my art :P

¿Por qué todo el mundo tiene que ser rubio?
Hoy en día todas las chicas quieren ser rubias y tener los
ojos azules. Echenle la culpa al Capitalismo y a sus famosos
iconos de Chicas Barbies, como la vulgar Lady Gaga (por si
aún no sea han dado cuenta, todo en ella es falso, empezando
por el falso azúl de sus ojos y terminando por su pelo teñido de
rubio platino). Pero hubo un tiempo, en los años treintas, en que
todas las chicas querían tener los cabellos oscuros, como Betty
Boop, un personaje de comic creado en 1930 durante la gran
depresión. Betty fue el primer símbolo sexual y no era de carne
y hueso, jajaja, muchos años antes que Mrilyn Monroe y Rita Hayworth,
ella ya lucía vestido cortos, tacones altos, liguero y un generoso
escote :P Algo muy revolucionario para la rancia moral de aquella
época, que defendía que las chicas buenas tenían que quedarse
en casa, limpiando, cocinando, cuídando de sus hijos, y satisfaciendo
a sus hombres. Esa es la razón por la que siempre he encontrado a
Betty muy divertida (añandanle a eso, que en los primeros bocetos
que dibujo Max Fleischer, ella tenía forma de caniche francés :D).
Olvidé decir que el personaje de Betty estaba inspirado en las
"chicas flapper", que escuchaban música Jazz, llevaban el pelo corto
(a lo garçon, o sea, a lo chico), y tenían un comportamiento rebelde
contra los hombres y la sociedad :D

The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.
WIKIPEDIA
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.

The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo.

"Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.

Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.
WIKIPEDIA
A dead muscoid fly (most likely Muscidae), killed by, and exuding spores of, an Entomophthora fungus (Class: Zygomycetes, Order: Entomophthorales).
Order: Entomophthorales
Obligate insect fungal pathogens that feed within the live host until all the resources are spent, thereby killing the insect - at which time the fungus must sporulate to infect new living hosts. They produce short term infecting spores (conidia) under favourable conditions (eg. good humidity) and long term hardy resting structures such as chlamydospores when conditions are not favourable. The resting structures will produce conidia when favourable conditions return. Entomophthora muscae is a well known species of this order that attacks the common housefly.
Entomophthora muscae
Infecting spores attach themselves to the fly's cuticle, penetrate it to reach the hemocoel (this is the common method of entry for insect pathogenic fungi), and then the fungus will grow within using the fly's nutrients (favouring the abdomen). When the fly dies, 5-8 days later, the white conidia will begin to disperse from between the abdominal segments within 3 hours and continue to do so for the next 10-21 hours.
Odd Behaviours and Lures
This fungus has fascinated me, especially for the way it is reported to hijack host behaviour and to set lures for potential hosts - both very successfully serving it's own greater good.
You'll notice in the photo above that the fly has died in a peculiar position. Infected flies will die in high positions, on the underside of overhanging objects, and with wings and legs outstretched - such positioning just prior to death is also observed for many other insects lethally infected with similar fungi. It is thought that this odd host behaviour rewiring by the pathogen increases successful spore dispersion and infection, especially of aerial insects.
Another trick Entomophthora muscae play to ensure greater spread through host populations is to make the dead female highly attractive to males. It has not yet been determined how the fungus achieves this but male flies who happen upon a sporulating female cadaver have no power to resist it and will immediately engage in "extensive courtship". Hence, potentially becoming infected themselves or even carrying infecting spores to another mate.
The Co-evolutionary Battle Heats Up
Flies invaded with Entomophthora fungi have clearly demonstrated 'behavioural fever' whereby they deliberately seek, and bask, in heats above 40 degrees Celsius in the first days of infection. The high raising of body temperatures acts to suppress the pathogen. The obvious benefits of fever are an increase in the onset time of the disease giving the fly a greater chance to complete it's lifecycle and thus pass on this beneficial trait. Fever therapy has also been observed in infected grasshoppers and caterpillars resulting in reduced mortality rates. So should you find your pet house fly 'liaising' with an infected dead fly, a program of sauna therapy is highly recommended.

Ebony Jewelwing (Calopteryx maculata) female and male behaviour (teaser).
Backus Woods, Norfolk County, Ontario, Canada.
June 25, 2020.
Please view full screen for best quality. ;-)
I'm editing several interesting clips together, but wanted to share this one short clip right away. ;-)
Ebony Jewelwings have very sophisticated courtship and ovipositing rituals. Females line the stream banks to watch males "joust" for their attention. FEMALES pick their partner based on these competitions. That's rare in the dragon-damselfly world. Typically, the male literally grabs a female by the scruff of her neck and hope she cooperates! @@
The reason these jousting sessions are so important to the females is because the males "hover guard" the female they mated with, to ensure that HIS progeny's eggs are safely laid in the stream (they lay their eggs on partially submerged logs, twigs or leaves.) She depends on the male's ability to stand guard while she lays her eggs.
Ebony Jewelwings (Calopteryx maculata) prefer relatively clear, fast-moving streams. The male sentry butts heads and chases away any other male that tries to interfere while she's laying her (HIS) eggs underwater (their nymphs are aquatic). I got video of that behaviour too, but I'll save that for later.
This sneak preview is something I've never seen before. A rival male managed to slip past the hover-guarding male and tossed the egg-laying female right off her log!!
I always thought the competing male would just want to mate, but he seems to be more interested in interrupting the egg-laying process.
These beautiful and fascinating creatures never cease to amaze! ❤

This is a metal and vinyl backed post card sized...thing I got at the 'antique mall' last weekend. It said "Indian public service cards" and came with that round thingy to hang it up with. I'm thinking the 'behaviours' are:
Sneezing or barfing at the dinner table, or possibly bulemia
Killing small animals while your sibling possibly falls in the river and drowns
Tripping a friend while playing ball in the street causing heinous vehicular injury
Beating up the kid you just played Texas Hold'em for lunch money and lost to
Dropping your leftover sugary cereal milk off the balcony and giving one of the strangely many passers-by crusty 'something about mary' hair
Touching someone's butt
I especially like the obvious consequences of the BAD BEHAVIOURS, like touching someone's butt will surely cause them to fall under the oncoming train.
I need a lover with a slow hand!
I need a lover with an easy touch...
Ok you can hum the other bits.😘
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.
WIKIPEDIA
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.

The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.
WIKIPEDIA
Excessive drinking is not only dangerous to your health but can leave you vulnerable to crime and violence.
Think Safe, Drink Safe aims to reduce alcohol-related crime, disorder and anti-social behaviour across Greater Manchester while promoting a safe night out.
The campaign was introduced following national concern about the developing rise in 'binge drinking' and promotes responsible drinking, raises awareness of the potential problems excessive drinking can lead to and encourages and promote the use of safe transport home.
Think Safe, Drink Safe was used effectively when changes to the licensing laws were introduced in November 2005 and police powers were increased including expanded closure powers and higher penalties for public order offences and drunk and disorderly.
As part of the campaign a variety of successful initiatives have been introduced across the Force area to discourage binge drinking and prevent alcohol related crime.
All Think Safe, Drink Safe initiatives are supported by a high profile, internationally acclaimed, advertising and marketing campaign, which features key messages such as 'Pace your drinks', 'Plan your night out' and 'Stay with friends'.
The campaign attempts to attack the culture of binge drinking and provides helpful advice and safety messages to late-night drinkers
Remember the following when planning a night out:
*Avoid trouble by walking away. If a friend starts becoming aggressive, calm them down , remove them from the situation and encourage them to sober up.
*Pace your drinks.
*Drink plenty of water.
*Always try to eat something before a night out.
*Don’t leave your drink unattended, even when going to the toilet.
*Never accept a drink from anyone you do not completely trust.
*Stay with friends or in a group.
*Go out together and leave together. Do not wander off from your friends without letting anyone know where you are going and arrange a meeting point in case you do get separated.
Take safe transport
*Pre-book a taxi to take you home and arrange to be picked up from a safe, and well-lit meeting point.
*Make sure the taxi you ordered is the one you get into.
*Know the car details and ensure the driver knows what name it was booked under.
*Find out where taxi ranks are and try to choose staffed ones.
*If alone, book a taxi firm you know and trust. Do not get a private hire car (they look like a normal car) unless you have booked them first. Only hackney carriages (traditional black cabs) are insured to carry passengers who have flagged them down.
*Always sit in the back, preferably behind the driver.
*Night buses run until around 3am in parts of Greater Manchester. Find out when the last bus leaves so that you don't become stranded.
*Try to catch the bus from stops with bus loaders. If there isn't any in your town, use well-lit bus stops in busy areas.
*If alone, sit as near to the driver as possible and avoid empty upper decks.
*Tell the driver or guard if someone bothers you.
*Avoid walking home alone. If you have no other choice, walk in the middle of the pavement, avoid short cuts and face ongoing traffic.
*If you think you are being followed, cross the street several times. If you still think you are being followed, walk to the busiest area you can find or knock on somebody's door.

The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.
WIKIPEDIA
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.
WIKIPEDIA
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.

__________________________
The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang, and Padar. A member of the monitor lizard family Varanidae, it is the largest living species of lizard, growing to a maximum length of 3 metres in rare cases and weighing up to approximately 70 kilograms.
Their unusually large size has been attributed to island gigantism, since no other carnivorous animals fill the niche on the islands where they live. However, recent research suggests the large size of Komodo dragons may be better understood as representative of a relict population of very large varanid lizards that once lived across Indonesia and Australia, most of which, along with other megafauna, died out after the Pleistocene. Fossils very similar to V. komodoensis have been found in Australia dating to greater than 3.8 million years ago, and its body size remained stable on Flores, one of the handful of Indonesian islands where it is currently found, over the last 900,000 years, "a time marked by major faunal turnovers, extinction of the island's megafauna, and the arrival of early hominids by 880 ka [kiloannums]."
As a result of their size, these lizards dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. It has been claimed that they have a venomous bite; there are two glands in the lower jaw which secrete several toxic proteins. The biological significance of these proteins is disputed, but the glands have been shown to secrete an anticoagulant. Komodo dragon group behaviour in hunting is exceptional in the reptile world. The diet of big Komodo dragons mainly consists of deer, though they also eat considerable amounts of carrion. Komodo dragons also occasionally attack humans in the area of West Manggarai Regency where they live in Indonesia.
Mating begins between May and August, and the eggs are laid in September. About 20 eggs are deposited in abandoned megapode nests or in a self-dug nesting hole. The eggs are incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take 8 to 9 years to mature, and are estimated to live up to 30 years.
Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild, their range has contracted due to human activities, and they are listed as vulnerable by the IUCN. They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.
ETYMOLOGY
The Komodo dragon is also known as the Komodo monitor or the Komodo Island monitor in scientific literature, although this is not very common. To the natives of Komodo Island, it is referred to as ora, buaya darat (land crocodile), or biawak raksasa (giant monitor).
EVOLUTIONARY HISTORY
The evolutionary development of the Komodo dragon started with the Varanus genus, which originated in Asia about 40 million years ago and migrated to Australia. Around 15 million years ago, a collision between Australia and Southeast Asia allowed the varanids to move into what is now the Indonesian archipelago, extending their range as far east as the island of Timor. The Komodo dragon was believed to have differentiated from its Australian ancestors 4 million years ago. However, recent fossil evidence from Queensland suggests the Komodo dragon evolved in Australia before spreading to Indonesia. Dramatic lowering of sea level during the last glacial period uncovered extensive stretches of continental shelf that the Komodo dragon colonized, becoming isolated in their present island range as sea levels rose afterwards.
DESCRIPTION
In the wild, an adult Komodo dragon usually weighs around 70 kg, although captive specimens often weigh more. According to the Guinness Book of World Records, an average adult male will weigh 79 to 91 kg and measure 2.59 m, while an average female will weigh 68 to 73 kg and measure 2.29 m. The largest verified wild specimen was 3.13 m long and weighed 166 kg, including undigested food. The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm in length. Its saliva is frequently blood-tinged, because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding. This creates an ideal culture for the bacteria that live in its mouth. It also has a long, yellow, deeply forked tongue. Komodo dragon skin is reinforced by armoured scales, which contain tiny bones called osteoderms that function as a sort of natural chain-mail. This rugged hide makes Komodo dragon skin poorly suited for making into leather.
SENSES
As with other Varanids, Komodo dragons have only a single ear bone, the stapes, for transferring vibrations from the tympanic membrane to the cochlea. This arrangement means they are likely restricted to sounds in the 400 to 2,000 hertz range, compared to humans who hear between 20 and 20,000 hertz. It was formerly thought to be deaf when a study reported no agitation in wild Komodo dragons in response to whispers, raised voices, or shouts. This was disputed when London Zoological Garden employee Joan Proctor trained a captive specimen to come out to feed at the sound of her voice, even when she could not be seen.
The Komodo dragon can see objects as far away as 300 m, but because its retinas only contain cones, it is thought to have poor night vision. The Komodo dragon is able to see in color, but has poor visual discrimination of stationary objects.
The Komodo dragon uses its tongue to detect, taste, and smell stimuli, as with many other reptiles, with the vomeronasal sense using the Jacobson's organ, rather than using the nostrils. With the help of a favorable wind and its habit of swinging its head from side to side as it walks, a Komodo dragon may be able to detect carrion from 4–9.5 km away. It only has a few taste buds in the back of its throat. Its scales, some of which are reinforced with bone, have sensory plaques connected to nerves to facilitate its sense of touch. The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques.
BEHAVIOUR AND ECOLOGY
The Komodo dragon prefers hot and dry places, and typically lives in dry, open grassland, savanna, and tropical forest at low elevations. As an ectotherm, it is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 km/h, diving up to 4.5 m, and climbing trees proficiently when young through use of their strong claws. To catch out-of-reach prey, the Komodo dragon may stand on its hind legs and use its tail as a support. As it matures, its claws are used primarily as weapons, as its great size makes climbing impractical.
For shelter, the Komodo dragon digs holes that can measure from 1–3 m wide with its powerful forelimbs and claws. Because of its large size and habit of sleeping in these burrows, it is able to conserve body heat throughout the night and minimize its basking period the morning after. The Komodo dragon hunts in the afternoon, but stays in the shade during the hottest part of the day. These special resting places, usually located on ridges with cool sea breezes, are marked with droppings and are cleared of vegetation. They serve as strategic locations from which to ambush deer.
DIET
Komodo dragons are carnivores. Although they eat mostly carrion, they will also ambush live prey with a stealthy approach. When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal and go for the underside or the throat. It is able to locate its prey using its keen sense of smell, which can locate a dead or dying animal from a range of up to 9.5 km. Komodo dragons have been observed knocking down large pigs and deer with their strong tails.
Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skulls, and expandable stomachs allow them to swallow prey whole. The vegetable contents of the stomach and intestines are typically avoided. Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully, the tree is knocked down. To prevent itself from suffocating while swallowing, it breathes using a small tube under the tongue that connects to the lungs. After eating up to 80% of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested for too long. Because of their slow metabolism, large dragons can survive on as little as 12 meals a year. After digestion, the Komodo dragon regurgitates a mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus, suggesting, like humans, it does not relish the scent of its own excretions.
The largest animals eat first, while the smaller ones follow a hierarchy. The largest male asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses. Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors.
The Komodo dragon's diet is wide-ranging, and includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boar, goats, deer, horses, and water buffalo. Young Komodos will eat insects, eggs, geckos, and small mammals. Occasionally, they consume humans and human corpses, digging up bodies from shallow graves. This habit of raiding graves caused the villagers of Komodo to move their graves from sandy to clay ground and pile rocks on top of them to deter the lizards. The Komodo dragon may have evolved to feed on the extinct dwarf elephant Stegodon that once lived on Flores, according to evolutionary biologist Jared Diamond.
The Komodo dragon drinks by sucking water into its mouth via buccal pumping (a process also used for respiration), lifting its head, and letting the water run down its throat.
SALIVA
Auffenberg described the Komodo dragon as having septic pathogens in its saliva (he described the saliva as "reddish and copious"), specifically the bacteria E. coli, Staphylococcus sp., Providencia sp., Proteus morgani, and P. mirabilis. He noted, while these pathogens can be found in the mouths of wild Komodo dragons, they disappear from the mouths of captive animals, due to cleaner diets and the use of antibiotics. This was verified by taking mucous samples from the external gum surfaces of the upper jaws of two freshly captured individuals. Saliva samples were analyzed by researchers at the University of Texas, who found 57 strains of bacteria growing in the mouths of three wild Komodo dragons, including Pasteurella multocida. The rapid growth of these bacteria was noted by Fredeking: "Normally it takes about three days for a sample of P. multocida to cover a Petri dish; ours took eight hours. We were very taken aback by how virulent these strains were". This study supported the observation that wounds inflicted by the Komodo dragon are often associated with sepsis and subsequent infections in prey animals. How the Komodo dragon is unaffected by these virulent bacteria remains a mystery.Research in 2013 suggested that the bacteria in the mouths of komodo dragons are ordinary and similar to those found in other carnivores. They actually have surprisingly good mouth hygiene. As Bryan Fry put it: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in the leaves to clean their mouth... Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria." The observation of prey dying of sepsis would then be explained by the natural instinct of water buffalos, who are not native to the islands where the Komodo dragon lives, to run into water when attacked. The warm, feces filled water would then cause the infections. The study used samples from 16 captive dragons (10 adults and six neonates) from three U.S. zoos.
VENOM
In late 2005, researchers at the University of Melbourne speculated the perentie (Varanus giganteus), other species of monitors, and agamids may be somewhat venomous. The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor (V. varius), a Komodo dragon, and a spotted tree monitor (V. scalaris) all produced similar effects: rapid swelling, localized disruption of blood clotting, and shooting pain up to the elbow, with some symptoms lasting for several hours.
In 2009, the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw. The researchers extracted one of these glands from the head of a terminally ill specimen in the Singapore Zoological Gardens, and found it secreted several different toxic proteins. The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness in envenomated prey. As a result of the discovery, the previous theory that bacteria were responsible for the deaths of Komodo victims was disputed.
Kurt Schwenk, an evolutionary biologist at the University of Connecticut, finds the discovery of these glands intriguing, but considers most of the evidence for venom in the study to be "meaningless, irrelevant, incorrect or falsely misleading". Even if the lizards have venom-like proteins in their mouths, Schwenk argues, they may be using them for a different function, and he doubts venom is necessary to explain the effect of a Komodo dragon bite, arguing that shock and blood loss are the primary factors.
Other scientists such as Washington State University's Biologist Kenneth V. Kardong and Toxicologists Scott A. Weinstein and Tamara L. Smith, have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced a very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution". According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey". These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses the biological assessment of squamate biochemical systems".
REPRODUCTION
Mating occurs between May and August, with the eggs laid in September. During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during the early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking. Copulation occurs when the male inserts one of his hemipenes into the female's cloaca. Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards. Female Komodos lay their eggs from August to September and may use several types of locality; in one study, 60% laid their eggs in the nests of orange-footed scrubfowl (a moundbuilder or megapode), 20% on ground level and 20% in hilly areas. The females make many camouflage nests/holes to prevent other dragons from eating the eggs. Clutches contain an average of 20 eggs, which have an incubation period of 7–8 months. Hatching is an exhausting effort for the neonates, which break out of their eggshells with an egg tooth that falls off soon after. After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation. Sixteen youngsters from a single nest were on average 46.5 cm long and weighed 105.1 grams. Young Komodo dragons spend much of their first few years in trees, where they are relatively safe from predators, including cannibalistic adults, as juvenile dragons make up 10% of their diets. The habit of cannibalism may be advantageous in sustaining the large size of adults, as medium-sized prey on the islands is rare. When the young approach a kill, they roll around in fecal matter and rest in the intestines of eviscerated animals to deter these hungry adults. Komodo dragons take approximately three to five years to mature, and may live for up to 50 years.
PARTHENOGENESIS
A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late 2005 after being separated from male company for more than two years. Scientists initially assumed she had been able to store sperm from her earlier encounter with a male, an adaptation known as superfecundation. On 20 December 2006, it was reported that Flora, a captive Komodo dragon living in the Chester Zoo in England, was the second known Komodo dragon to have laid unfertilized eggs: she laid 11 eggs, and seven of them hatched, all of them male. Scientists at Liverpool University in England performed genetic tests on three eggs that collapsed after being moved to an incubator, and verified Flora had never been in physical contact with a male dragon. After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. On 31 January 2008, the Sedgwick County Zoo in Wichita, Kansas, became the first zoo in the Americas to document parthenogenesis in Komodo dragons. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19–20 May 2007. Only two eggs were incubated and hatched due to space issues; the first hatched on 31 January 2008, while the second hatched on 1 February. Both hatchlings were males.
Komodo dragons have the ZW chromosomal sex-determination system, as opposed to the mammalian XY system. Male progeny prove Flora's unfertilized eggs were haploid (n) and doubled their chromosomes later to become diploid (2n) (by being fertilized by a polar body, or by chromosome duplication without cell division), rather than by her laying diploid eggs by one of the meiosis reduction-divisions in her ovaries failing. When a female Komodo dragon (with ZW sex chromosomes) reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes. This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ (male); those receiving a W chromosome become WW and fail to develop, meaning that only males are produced by parthenogenesis in this species.
It has been hypothesized that this reproductive adaptation allows a single female to enter an isolated ecological niche (such as an island) and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population (via reproduction with her offspring that can result in both male and female young). Despite the advantages of such an adaptation, zoos are cautioned that parthenogenesis may be detrimental to genetic diversity.
HISTORY
DISCOVERY BY THE WESTERN WORLD
Komodo dragons were first documented by Europeans in 1910, when rumors of a "land crocodile" reached Lieutenant van Steyn van Hensbroek of the Dutch colonial administration. Widespread notoriety came after 1912, when Peter Ouwens, the director of the Zoological Museum at Bogor, Java, published a paper on the topic after receiving a photo and a skin from the lieutenant, as well as two other specimens from a collector. The first two live Komodo dragons to arrive in Europe were exhibited in the Reptile House at London Zoo when it opened in 1927. Joan Beauchamp Procter made some of the earliest observations of these animals in captivity and she demonstrated the behaviour of one of these animals at a Scientific Meeting of the Zoological Society of London in 1928. The Komodo dragon was the driving factor for an expedition to Komodo Island by W. Douglas Burden in 1926. After returning with 12 preserved specimens and 2 live ones, this expedition provided the inspiration for the 1933 movie King Kong. It was also Burden who coined the common name "Komodo dragon." Three of his specimens were stuffed and are still on display in the American Museum of Natural History.
STUDIES
The Dutch, realizing the limited number of individuals in the wild, outlawed sport hunting and heavily limited the number of individuals taken for scientific study. Collecting expeditions ground to a halt with the occurrence of World War II, not resuming until the 1950s and 1960s, when studies examined the Komodo dragon's feeding behavior, reproduction, and body temperature. At around this time, an expedition was planned in which a long-term study of the Komodo dragon would be undertaken. This task was given to the Auffenberg family, who stayed on Komodo Island for 11 months in 1969. During their stay, Walter Auffenberg and his assistant Putra Sastrawan captured and tagged more than 50 Komodo dragons. The research from the Auffenberg expedition would prove to be enormously influential in raising Komodo dragons in captivity. Research after that of the Auffenberg family has shed more light on the nature of the Komodo dragon, with biologists such as Claudio Ciofi continuing to study the creatures.
CONSERVATION
The Komodo dragon is a vulnerable species and is on the IUCN Red List. There are approximately 4,000 to 5,000 living Komodo dragons in the wild. Their populations are restricted to the islands of Gili Motang (100), Gili Dasami (100), Rinca (1,300), Komodo (1,700), and Flores (perhaps 2,000). However, there are concerns that there may presently be only 350 breeding females. To address these concerns, the Komodo National Park was founded in 1980 to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar. Later, the Wae Wuul and Wolo Tado Reserves were opened on Flores to aid with Komodo dragon conservation.
Komodo dragons avoid encounters with humans. Juveniles are very shy and will flee quickly into a hideout if a human comes closer than about 100 metres. Older animals will also retreat from humans from a shorter distance away. If cornered, they will react aggressively by gaping their mouth, hissing, and swinging their tail. If they are disturbed further, they may start an attack and bite. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or caused by defensive bites. Only a very few cases are truly the result of unprovoked attacks by abnormal individuals, which lost their fear towards humans.
Volcanic activity, earthquakes, loss of habitat, fire, loss of prey due to poaching, tourism, and illegal poaching of the dragons themselves have all contributed to the vulnerable status of the Komodo dragon. Under Appendix I of CITES (the Convention on International Trade in Endangered Species), commercial trade of skins or specimens is illegal.
On Padar, a former population of the Komodo dragon became extinct, of which the last individuals were seen in 1975. It is widely assumed that the Komodo dragon died out on Padar after a strong decline of the populations of large ungulate prey, for which poaching was most likely responsible.
IN CAPTIVITY
Komodo dragons have long been great zoo attractions, where their size and reputation make them popular exhibits. They are, however, rare in zoos because they are susceptible to infection and parasitic disease if captured from the wild, and do not readily reproduce. As of May 2009, there were 13 European, 2 African, 35 North American, 1 Singaporean, and 2 Australian institutions that kept Komodo dragons.
The first Komodo dragons were displayed at London Zoo in 1927. A Komodo dragon was exhibited in 1934 at the National Zoo in Washington, D.C., but it lived for only two years. More attempts to exhibit Komodo dragons were made, but the lifespan of these animals was very short, averaging five years in the National Zoological Park. Studies done by Walter Auffenberg, which were documented in his book The Behavioral Ecology of the Komodo Monitor, eventually allowed for more successful managing and reproducing of the dragons in captivity.
A variety of behaviors have been observed from captive specimens. Most individuals are relatively tame within a short time, and are capable of recognizing individual humans and discriminating between familiar keepers. Komodo dragons have also been observed to engage in play with a variety of objects, including shovels, cans, plastic rings, and shoes. This behavior does not seem to be "food-motivated predatory behavior".
Even seemingly docile dragons may become unpredictably aggressive, especially when the animal's territory is invaded by someone unfamiliar. In June 2001, a Komodo dragon seriously injured Phil Bronstein, the then husband of actress Sharon Stone, when he entered its enclosure at the Los Angeles Zoo after being invited in by its keeper. Bronstein was bitten on his bare foot, as the keeper had told him to take off his white shoes and socks, which the keeper stated could potentially excite the Komodo dragon as they were the same color as the white rats the zoo fed the dragon. Although he escaped, Bronstein needed to have several tendons in his foot reattached surgically.
IN POPULARE CULTURE
Komodo dragons are used as a main theme in Komodo (1999), Curse of the Komodo (2004) and Komodo vs. Cobra (2005).
The comedy team of Bob and Ray performed a popular sketch entitled "The Komodo Dragon Expert."
The plot of the 1990 film, The Freshman, involves a university freshman, an aging mobster and a Komodo dragon.
In the 2012 James Bond film Skyfall, one of the Chinese henchmen in a casino that Bond visits in Macau is overtaken, dragged off and presumably killed by a Komodo dragon.

. . . this is not in a zoo - it is wildlife! One hit with their giant claws and you are damaged! Luckily they are not aggressive . . .
__________________________
The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang, and Padar. A member of the monitor lizard family Varanidae, it is the largest living species of lizard, growing to a maximum length of 3 metres in rare cases and weighing up to approximately 70 kilograms.
Their unusually large size has been attributed to island gigantism, since no other carnivorous animals fill the niche on the islands where they live. However, recent research suggests the large size of Komodo dragons may be better understood as representative of a relict population of very large varanid lizards that once lived across Indonesia and Australia, most of which, along with other megafauna, died out after the Pleistocene. Fossils very similar to V. komodoensis have been found in Australia dating to greater than 3.8 million years ago, and its body size remained stable on Flores, one of the handful of Indonesian islands where it is currently found, over the last 900,000 years, "a time marked by major faunal turnovers, extinction of the island's megafauna, and the arrival of early hominids by 880 ka [kiloannums]."
As a result of their size, these lizards dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. It has been claimed that they have a venomous bite; there are two glands in the lower jaw which secrete several toxic proteins. The biological significance of these proteins is disputed, but the glands have been shown to secrete an anticoagulant. Komodo dragon group behaviour in hunting is exceptional in the reptile world. The diet of big Komodo dragons mainly consists of deer, though they also eat considerable amounts of carrion. Komodo dragons also occasionally attack humans in the area of West Manggarai Regency where they live in Indonesia.
Mating begins between May and August, and the eggs are laid in September. About 20 eggs are deposited in abandoned megapode nests or in a self-dug nesting hole. The eggs are incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take 8 to 9 years to mature, and are estimated to live up to 30 years.
Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild, their range has contracted due to human activities, and they are listed as vulnerable by the IUCN. They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.
ETYMOLOGY
The Komodo dragon is also known as the Komodo monitor or the Komodo Island monitor in scientific literature, although this is not very common. To the natives of Komodo Island, it is referred to as ora, buaya darat (land crocodile), or biawak raksasa (giant monitor).
EVOLUTIONARY HISTORY
The evolutionary development of the Komodo dragon started with the Varanus genus, which originated in Asia about 40 million years ago and migrated to Australia. Around 15 million years ago, a collision between Australia and Southeast Asia allowed the varanids to move into what is now the Indonesian archipelago, extending their range as far east as the island of Timor. The Komodo dragon was believed to have differentiated from its Australian ancestors 4 million years ago. However, recent fossil evidence from Queensland suggests the Komodo dragon evolved in Australia before spreading to Indonesia. Dramatic lowering of sea level during the last glacial period uncovered extensive stretches of continental shelf that the Komodo dragon colonized, becoming isolated in their present island range as sea levels rose afterwards.
DESCRIPTION
In the wild, an adult Komodo dragon usually weighs around 70 kg, although captive specimens often weigh more. According to the Guinness Book of World Records, an average adult male will weigh 79 to 91 kg and measure 2.59 m, while an average female will weigh 68 to 73 kg and measure 2.29 m. The largest verified wild specimen was 3.13 m long and weighed 166 kg, including undigested food. The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm in length. Its saliva is frequently blood-tinged, because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding. This creates an ideal culture for the bacteria that live in its mouth. It also has a long, yellow, deeply forked tongue. Komodo dragon skin is reinforced by armoured scales, which contain tiny bones called osteoderms that function as a sort of natural chain-mail. This rugged hide makes Komodo dragon skin poorly suited for making into leather.
SENSES
As with other Varanids, Komodo dragons have only a single ear bone, the stapes, for transferring vibrations from the tympanic membrane to the cochlea. This arrangement means they are likely restricted to sounds in the 400 to 2,000 hertz range, compared to humans who hear between 20 and 20,000 hertz. It was formerly thought to be deaf when a study reported no agitation in wild Komodo dragons in response to whispers, raised voices, or shouts. This was disputed when London Zoological Garden employee Joan Proctor trained a captive specimen to come out to feed at the sound of her voice, even when she could not be seen.
The Komodo dragon can see objects as far away as 300 m, but because its retinas only contain cones, it is thought to have poor night vision. The Komodo dragon is able to see in color, but has poor visual discrimination of stationary objects.
The Komodo dragon uses its tongue to detect, taste, and smell stimuli, as with many other reptiles, with the vomeronasal sense using the Jacobson's organ, rather than using the nostrils. With the help of a favorable wind and its habit of swinging its head from side to side as it walks, a Komodo dragon may be able to detect carrion from 4–9.5 km away. It only has a few taste buds in the back of its throat. Its scales, some of which are reinforced with bone, have sensory plaques connected to nerves to facilitate its sense of touch. The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques.
BEHAVIOUR AND ECOLOGY
The Komodo dragon prefers hot and dry places, and typically lives in dry, open grassland, savanna, and tropical forest at low elevations. As an ectotherm, it is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 km/h, diving up to 4.5 m, and climbing trees proficiently when young through use of their strong claws. To catch out-of-reach prey, the Komodo dragon may stand on its hind legs and use its tail as a support. As it matures, its claws are used primarily as weapons, as its great size makes climbing impractical.
For shelter, the Komodo dragon digs holes that can measure from 1–3 m wide with its powerful forelimbs and claws. Because of its large size and habit of sleeping in these burrows, it is able to conserve body heat throughout the night and minimize its basking period the morning after. The Komodo dragon hunts in the afternoon, but stays in the shade during the hottest part of the day. These special resting places, usually located on ridges with cool sea breezes, are marked with droppings and are cleared of vegetation. They serve as strategic locations from which to ambush deer.
DIET
Komodo dragons are carnivores. Although they eat mostly carrion, they will also ambush live prey with a stealthy approach. When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal and go for the underside or the throat. It is able to locate its prey using its keen sense of smell, which can locate a dead or dying animal from a range of up to 9.5 km. Komodo dragons have been observed knocking down large pigs and deer with their strong tails.
Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skulls, and expandable stomachs allow them to swallow prey whole. The vegetable contents of the stomach and intestines are typically avoided. Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully, the tree is knocked down. To prevent itself from suffocating while swallowing, it breathes using a small tube under the tongue that connects to the lungs. After eating up to 80% of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested for too long. Because of their slow metabolism, large dragons can survive on as little as 12 meals a year. After digestion, the Komodo dragon regurgitates a mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus, suggesting, like humans, it does not relish the scent of its own excretions.
The largest animals eat first, while the smaller ones follow a hierarchy. The largest male asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses. Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors.
The Komodo dragon's diet is wide-ranging, and includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boar, goats, deer, horses, and water buffalo. Young Komodos will eat insects, eggs, geckos, and small mammals. Occasionally, they consume humans and human corpses, digging up bodies from shallow graves. This habit of raiding graves caused the villagers of Komodo to move their graves from sandy to clay ground and pile rocks on top of them to deter the lizards. The Komodo dragon may have evolved to feed on the extinct dwarf elephant Stegodon that once lived on Flores, according to evolutionary biologist Jared Diamond.
The Komodo dragon drinks by sucking water into its mouth via buccal pumping (a process also used for respiration), lifting its head, and letting the water run down its throat.
SALIVA
Auffenberg described the Komodo dragon as having septic pathogens in its saliva (he described the saliva as "reddish and copious"), specifically the bacteria E. coli, Staphylococcus sp., Providencia sp., Proteus morgani, and P. mirabilis. He noted, while these pathogens can be found in the mouths of wild Komodo dragons, they disappear from the mouths of captive animals, due to cleaner diets and the use of antibiotics. This was verified by taking mucous samples from the external gum surfaces of the upper jaws of two freshly captured individuals. Saliva samples were analyzed by researchers at the University of Texas, who found 57 strains of bacteria growing in the mouths of three wild Komodo dragons, including Pasteurella multocida. The rapid growth of these bacteria was noted by Fredeking: "Normally it takes about three days for a sample of P. multocida to cover a Petri dish; ours took eight hours. We were very taken aback by how virulent these strains were". This study supported the observation that wounds inflicted by the Komodo dragon are often associated with sepsis and subsequent infections in prey animals. How the Komodo dragon is unaffected by these virulent bacteria remains a mystery.Research in 2013 suggested that the bacteria in the mouths of komodo dragons are ordinary and similar to those found in other carnivores. They actually have surprisingly good mouth hygiene. As Bryan Fry put it: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in the leaves to clean their mouth... Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria." The observation of prey dying of sepsis would then be explained by the natural instinct of water buffalos, who are not native to the islands where the Komodo dragon lives, to run into water when attacked. The warm, feces filled water would then cause the infections. The study used samples from 16 captive dragons (10 adults and six neonates) from three U.S. zoos.
VENOM
In late 2005, researchers at the University of Melbourne speculated the perentie (Varanus giganteus), other species of monitors, and agamids may be somewhat venomous. The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor (V. varius), a Komodo dragon, and a spotted tree monitor (V. scalaris) all produced similar effects: rapid swelling, localized disruption of blood clotting, and shooting pain up to the elbow, with some symptoms lasting for several hours.
In 2009, the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw. The researchers extracted one of these glands from the head of a terminally ill specimen in the Singapore Zoological Gardens, and found it secreted several different toxic proteins. The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness in envenomated prey. As a result of the discovery, the previous theory that bacteria were responsible for the deaths of Komodo victims was disputed.
Kurt Schwenk, an evolutionary biologist at the University of Connecticut, finds the discovery of these glands intriguing, but considers most of the evidence for venom in the study to be "meaningless, irrelevant, incorrect or falsely misleading". Even if the lizards have venom-like proteins in their mouths, Schwenk argues, they may be using them for a different function, and he doubts venom is necessary to explain the effect of a Komodo dragon bite, arguing that shock and blood loss are the primary factors.
Other scientists such as Washington State University's Biologist Kenneth V. Kardong and Toxicologists Scott A. Weinstein and Tamara L. Smith, have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced a very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution". According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey". These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses the biological assessment of squamate biochemical systems".
REPRODUCTION
Mating occurs between May and August, with the eggs laid in September. During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during the early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking. Copulation occurs when the male inserts one of his hemipenes into the female's cloaca. Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards. Female Komodos lay their eggs from August to September and may use several types of locality; in one study, 60% laid their eggs in the nests of orange-footed scrubfowl (a moundbuilder or megapode), 20% on ground level and 20% in hilly areas. The females make many camouflage nests/holes to prevent other dragons from eating the eggs. Clutches contain an average of 20 eggs, which have an incubation period of 7–8 months. Hatching is an exhausting effort for the neonates, which break out of their eggshells with an egg tooth that falls off soon after. After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation. Sixteen youngsters from a single nest were on average 46.5 cm long and weighed 105.1 grams. Young Komodo dragons spend much of their first few years in trees, where they are relatively safe from predators, including cannibalistic adults, as juvenile dragons make up 10% of their diets. The habit of cannibalism may be advantageous in sustaining the large size of adults, as medium-sized prey on the islands is rare. When the young approach a kill, they roll around in fecal matter and rest in the intestines of eviscerated animals to deter these hungry adults. Komodo dragons take approximately three to five years to mature, and may live for up to 50 years.
PARTHENOGENESIS
A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late 2005 after being separated from male company for more than two years. Scientists initially assumed she had been able to store sperm from her earlier encounter with a male, an adaptation known as superfecundation. On 20 December 2006, it was reported that Flora, a captive Komodo dragon living in the Chester Zoo in England, was the second known Komodo dragon to have laid unfertilized eggs: she laid 11 eggs, and seven of them hatched, all of them male. Scientists at Liverpool University in England performed genetic tests on three eggs that collapsed after being moved to an incubator, and verified Flora had never been in physical contact with a male dragon. After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. On 31 January 2008, the Sedgwick County Zoo in Wichita, Kansas, became the first zoo in the Americas to document parthenogenesis in Komodo dragons. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19–20 May 2007. Only two eggs were incubated and hatched due to space issues; the first hatched on 31 January 2008, while the second hatched on 1 February. Both hatchlings were males.
Komodo dragons have the ZW chromosomal sex-determination system, as opposed to the mammalian XY system. Male progeny prove Flora's unfertilized eggs were haploid (n) and doubled their chromosomes later to become diploid (2n) (by being fertilized by a polar body, or by chromosome duplication without cell division), rather than by her laying diploid eggs by one of the meiosis reduction-divisions in her ovaries failing. When a female Komodo dragon (with ZW sex chromosomes) reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes. This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ (male); those receiving a W chromosome become WW and fail to develop, meaning that only males are produced by parthenogenesis in this species.
It has been hypothesized that this reproductive adaptation allows a single female to enter an isolated ecological niche (such as an island) and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population (via reproduction with her offspring that can result in both male and female young). Despite the advantages of such an adaptation, zoos are cautioned that parthenogenesis may be detrimental to genetic diversity.

Their unusually large size has been attributed to island gigantism, since no other carnivorous animals fill the niche on the islands where they live. However, recent research suggests the large size of Komodo dragons may be better understood as representative of a relict population of very large varanid lizards that once lived across Indonesia and Australia, most of which, along with other megafauna, died out after the Pleistocene. Fossils very similar to V. komodoensis have been found in Australia dating to greater than 3.8 million years ago, and its body size remained stable on Flores, one of the handful of Indonesian islands where it is currently found, over the last 900,000 years, "a time marked by major faunal turnovers, extinction of the island's megafauna, and the arrival of early hominids by 880 ka [kiloannums]."
As a result of their size, these lizards dominate the ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates, birds, and mammals. It has been claimed that they have a venomous bite; there are two glands in the lower jaw which secrete several toxic proteins. The biological significance of these proteins is disputed, but the glands have been shown to secrete an anticoagulant. Komodo dragon group behaviour in hunting is exceptional in the reptile world. The diet of big Komodo dragons mainly consists of deer, though they also eat considerable amounts of carrion. Komodo dragons also occasionally attack humans in the area of West Manggarai Regency where they live in Indonesia.
Mating begins between May and August, and the eggs are laid in September. About 20 eggs are deposited in abandoned megapode nests or in a self-dug nesting hole. The eggs are incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take 8 to 9 years to mature, and are estimated to live up to 30 years.
Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild, their range has contracted due to human activities, and they are listed as vulnerable by the IUCN. They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.
ETYMOLOGY
The Komodo dragon is also known as the Komodo monitor or the Komodo Island monitor in scientific literature, although this is not very common. To the natives of Komodo Island, it is referred to as ora, buaya darat (land crocodile), or biawak raksasa (giant monitor).
EVOLUTIONARY HISTORY
The evolutionary development of the Komodo dragon started with the Varanus genus, which originated in Asia about 40 million years ago and migrated to Australia. Around 15 million years ago, a collision between Australia and Southeast Asia allowed the varanids to move into what is now the Indonesian archipelago, extending their range as far east as the island of Timor. The Komodo dragon was believed to have differentiated from its Australian ancestors 4 million years ago. However, recent fossil evidence from Queensland suggests the Komodo dragon evolved in Australia before spreading to Indonesia. Dramatic lowering of sea level during the last glacial period uncovered extensive stretches of continental shelf that the Komodo dragon colonized, becoming isolated in their present island range as sea levels rose afterwards.
DESCRIPTION
In the wild, an adult Komodo dragon usually weighs around 70 kg, although captive specimens often weigh more. According to the Guinness Book of World Records, an average adult male will weigh 79 to 91 kg and measure 2.59 m, while an average female will weigh 68 to 73 kg and measure 2.29 m. The largest verified wild specimen was 3.13 m long and weighed 166 kg, including undigested food. The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm in length. Its saliva is frequently blood-tinged, because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding. This creates an ideal culture for the bacteria that live in its mouth. It also has a long, yellow, deeply forked tongue. Komodo dragon skin is reinforced by armoured scales, which contain tiny bones called osteoderms that function as a sort of natural chain-mail. This rugged hide makes Komodo dragon skin poorly suited for making into leather.
SENSES
As with other Varanids, Komodo dragons have only a single ear bone, the stapes, for transferring vibrations from the tympanic membrane to the cochlea. This arrangement means they are likely restricted to sounds in the 400 to 2,000 hertz range, compared to humans who hear between 20 and 20,000 hertz. It was formerly thought to be deaf when a study reported no agitation in wild Komodo dragons in response to whispers, raised voices, or shouts. This was disputed when London Zoological Garden employee Joan Proctor trained a captive specimen to come out to feed at the sound of her voice, even when she could not be seen.
The Komodo dragon can see objects as far away as 300 m, but because its retinas only contain cones, it is thought to have poor night vision. The Komodo dragon is able to see in color, but has poor visual discrimination of stationary objects.
The Komodo dragon uses its tongue to detect, taste, and smell stimuli, as with many other reptiles, with the vomeronasal sense using the Jacobson's organ, rather than using the nostrils. With the help of a favorable wind and its habit of swinging its head from side to side as it walks, a Komodo dragon may be able to detect carrion from 4–9.5 km away. It only has a few taste buds in the back of its throat. Its scales, some of which are reinforced with bone, have sensory plaques connected to nerves to facilitate its sense of touch. The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques.
BEHAVIOUR AND ECOLOGY
The Komodo dragon prefers hot and dry places, and typically lives in dry, open grassland, savanna, and tropical forest at low elevations. As an ectotherm, it is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 km/h, diving up to 4.5 m, and climbing trees proficiently when young through use of their strong claws. To catch out-of-reach prey, the Komodo dragon may stand on its hind legs and use its tail as a support. As it matures, its claws are used primarily as weapons, as its great size makes climbing impractical.
For shelter, the Komodo dragon digs holes that can measure from 1–3 m wide with its powerful forelimbs and claws. Because of its large size and habit of sleeping in these burrows, it is able to conserve body heat throughout the night and minimize its basking period the morning after. The Komodo dragon hunts in the afternoon, but stays in the shade during the hottest part of the day. These special resting places, usually located on ridges with cool sea breezes, are marked with droppings and are cleared of vegetation. They serve as strategic locations from which to ambush deer.
DIET
Komodo dragons are carnivores. Although they eat mostly carrion, they will also ambush live prey with a stealthy approach. When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal and go for the underside or the throat. It is able to locate its prey using its keen sense of smell, which can locate a dead or dying animal from a range of up to 9.5 km. Komodo dragons have been observed knocking down large pigs and deer with their strong tails.
Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skulls, and expandable stomachs allow them to swallow prey whole. The vegetable contents of the stomach and intestines are typically avoided. Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully, the tree is knocked down. To prevent itself from suffocating while swallowing, it breathes using a small tube under the tongue that connects to the lungs. After eating up to 80% of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested for too long. Because of their slow metabolism, large dragons can survive on as little as 12 meals a year. After digestion, the Komodo dragon regurgitates a mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus, suggesting, like humans, it does not relish the scent of its own excretions.
The largest animals eat first, while the smaller ones follow a hierarchy. The largest male asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses. Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors.
The Komodo dragon's diet is wide-ranging, and includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boar, goats, deer, horses, and water buffalo. Young Komodos will eat insects, eggs, geckos, and small mammals. Occasionally, they consume humans and human corpses, digging up bodies from shallow graves. This habit of raiding graves caused the villagers of Komodo to move their graves from sandy to clay ground and pile rocks on top of them to deter the lizards. The Komodo dragon may have evolved to feed on the extinct dwarf elephant Stegodon that once lived on Flores, according to evolutionary biologist Jared Diamond.
The Komodo dragon drinks by sucking water into its mouth via buccal pumping (a process also used for respiration), lifting its head, and letting the water run down its throat.
SALIVA
Auffenberg described the Komodo dragon as having septic pathogens in its saliva (he described the saliva as "reddish and copious"), specifically the bacteria E. coli, Staphylococcus sp., Providencia sp., Proteus morgani, and P. mirabilis. He noted, while these pathogens can be found in the mouths of wild Komodo dragons, they disappear from the mouths of captive animals, due to cleaner diets and the use of antibiotics. This was verified by taking mucous samples from the external gum surfaces of the upper jaws of two freshly captured individuals. Saliva samples were analyzed by researchers at the University of Texas, who found 57 strains of bacteria growing in the mouths of three wild Komodo dragons, including Pasteurella multocida. The rapid growth of these bacteria was noted by Fredeking: "Normally it takes about three days for a sample of P. multocida to cover a Petri dish; ours took eight hours. We were very taken aback by how virulent these strains were". This study supported the observation that wounds inflicted by the Komodo dragon are often associated with sepsis and subsequent infections in prey animals. How the Komodo dragon is unaffected by these virulent bacteria remains a mystery.Research in 2013 suggested that the bacteria in the mouths of komodo dragons are ordinary and similar to those found in other carnivores. They actually have surprisingly good mouth hygiene. As Bryan Fry put it: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in the leaves to clean their mouth... Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria." The observation of prey dying of sepsis would then be explained by the natural instinct of water buffalos, who are not native to the islands where the Komodo dragon lives, to run into water when attacked. The warm, feces filled water would then cause the infections. The study used samples from 16 captive dragons (10 adults and six neonates) from three U.S. zoos.
VENOM
In late 2005, researchers at the University of Melbourne speculated the perentie (Varanus giganteus), other species of monitors, and agamids may be somewhat venomous. The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor (V. varius), a Komodo dragon, and a spotted tree monitor (V. scalaris) all produced similar effects: rapid swelling, localized disruption of blood clotting, and shooting pain up to the elbow, with some symptoms lasting for several hours.
In 2009, the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw. The researchers extracted one of these glands from the head of a terminally ill specimen in the Singapore Zoological Gardens, and found it secreted several different toxic proteins. The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness in envenomated prey. As a result of the discovery, the previous theory that bacteria were responsible for the deaths of Komodo victims was disputed.
Kurt Schwenk, an evolutionary biologist at the University of Connecticut, finds the discovery of these glands intriguing, but considers most of the evidence for venom in the study to be "meaningless, irrelevant, incorrect or falsely misleading". Even if the lizards have venom-like proteins in their mouths, Schwenk argues, they may be using them for a different function, and he doubts venom is necessary to explain the effect of a Komodo dragon bite, arguing that shock and blood loss are the primary factors.
Other scientists such as Washington State University's Biologist Kenneth V. Kardong and Toxicologists Scott A. Weinstein and Tamara L. Smith, have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced a very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution". According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey". These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses the biological assessment of squamate biochemical systems".
REPRODUCTION
Mating occurs between May and August, with the eggs laid in September. During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during the early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking. Copulation occurs when the male inserts one of his hemipenes into the female's cloaca. Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards. Female Komodos lay their eggs from August to September and may use several types of locality; in one study, 60% laid their eggs in the nests of orange-footed scrubfowl (a moundbuilder or megapode), 20% on ground level and 20% in hilly areas. The females make many camouflage nests/holes to prevent other dragons from eating the eggs. Clutches contain an average of 20 eggs, which have an incubation period of 7–8 months. Hatching is an exhausting effort for the neonates, which break out of their eggshells with an egg tooth that falls off soon after. After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation. Sixteen youngsters from a single nest were on average 46.5 cm long and weighed 105.1 grams. Young Komodo dragons spend much of their first few years in trees, where they are relatively safe from predators, including cannibalistic adults, as juvenile dragons make up 10% of their diets. The habit of cannibalism may be advantageous in sustaining the large size of adults, as medium-sized prey on the islands is rare. When the young approach a kill, they roll around in fecal matter and rest in the intestines of eviscerated animals to deter these hungry adults. Komodo dragons take approximately three to five years to mature, and may live for up to 50 years.
PARTHENOGENESIS
A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late 2005 after being separated from male company for more than two years. Scientists initially assumed she had been able to store sperm from her earlier encounter with a male, an adaptation known as superfecundation. On 20 December 2006, it was reported that Flora, a captive Komodo dragon living in the Chester Zoo in England, was the second known Komodo dragon to have laid unfertilized eggs: she laid 11 eggs, and seven of them hatched, all of them male. Scientists at Liverpool University in England performed genetic tests on three eggs that collapsed after being moved to an incubator, and verified Flora had never been in physical contact with a male dragon. After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. On 31 January 2008, the Sedgwick County Zoo in Wichita, Kansas, became the first zoo in the Americas to document parthenogenesis in Komodo dragons. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19–20 May 2007. Only two eggs were incubated and hatched due to space issues; the first hatched on 31 January 2008, while the second hatched on 1 February. Both hatchlings were males.
Komodo dragons have the ZW chromosomal sex-determination system, as opposed to the mammalian XY system. Male progeny prove Flora's unfertilized eggs were haploid (n) and doubled their chromosomes later to become diploid (2n) (by being fertilized by a polar body, or by chromosome duplication without cell division), rather than by her laying diploid eggs by one of the meiosis reduction-divisions in her ovaries failing. When a female Komodo dragon (with ZW sex chromosomes) reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes. This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ (male); those receiving a W chromosome become WW and fail to develop, meaning that only males are produced by parthenogenesis in this species.
It has been hypothesized that this reproductive adaptation allows a single female to enter an isolated ecological niche (such as an island) and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population (via reproduction with her offspring that can result in both male and female young). Despite the advantages of such an adaptation, zoos are cautioned that parthenogenesis may be detrimental to genetic diversity.
HISTORY
DISCOVERY BY THE WESTERN WORLD
Komodo dragons were first documented by Europeans in 1910, when rumors of a "land crocodile" reached Lieutenant van Steyn van Hensbroek of the Dutch colonial administration. Widespread notoriety came after 1912, when Peter Ouwens, the director of the Zoological Museum at Bogor, Java, published a paper on the topic after receiving a photo and a skin from the lieutenant, as well as two other specimens from a collector. The first two live Komodo dragons to arrive in Europe were exhibited in the Reptile House at London Zoo when it opened in 1927. Joan Beauchamp Procter made some of the earliest observations of these animals in captivity and she demonstrated the behaviour of one of these animals at a Scientific Meeting of the Zoological Society of London in 1928. The Komodo dragon was the driving factor for an expedition to Komodo Island by W. Douglas Burden in 1926. After returning with 12 preserved specimens and 2 live ones, this expedition provided the inspiration for the 1933 movie King Kong. It was also Burden who coined the common name "Komodo dragon." Three of his specimens were stuffed and are still on display in the American Museum of Natural History.
STUDIES
The Dutch, realizing the limited number of individuals in the wild, outlawed sport hunting and heavily limited the number of individuals taken for scientific study. Collecting expeditions ground to a halt with the occurrence of World War II, not resuming until the 1950s and 1960s, when studies examined the Komodo dragon's feeding behavior, reproduction, and body temperature. At around this time, an expedition was planned in which a long-term study of the Komodo dragon would be undertaken. This task was given to the Auffenberg family, who stayed on Komodo Island for 11 months in 1969. During their stay, Walter Auffenberg and his assistant Putra Sastrawan captured and tagged more than 50 Komodo dragons. The research from the Auffenberg expedition would prove to be enormously influential in raising Komodo dragons in captivity. Research after that of the Auffenberg family has shed more light on the nature of the Komodo dragon, with biologists such as Claudio Ciofi continuing to study the creatures.
CONSERVATION
The Komodo dragon is a vulnerable species and is on the IUCN Red List. There are approximately 4,000 to 5,000 living Komodo dragons in the wild. Their populations are restricted to the islands of Gili Motang (100), Gili Dasami (100), Rinca (1,300), Komodo (1,700), and Flores (perhaps 2,000). However, there are concerns that there may presently be only 350 breeding females. To address these concerns, the Komodo National Park was founded in 1980 to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar. Later, the Wae Wuul and Wolo Tado Reserves were opened on Flores to aid with Komodo dragon conservation.
Komodo dragons avoid encounters with humans. Juveniles are very shy and will flee quickly into a hideout if a human comes closer than about 100 metres. Older animals will also retreat from humans from a shorter distance away. If cornered, they will react aggressively by gaping their mouth, hissing, and swinging their tail. If they are disturbed further, they may start an attack and bite. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or caused by defensive bites. Only a very few cases are truly the result of unprovoked attacks by abnormal individuals, which lost their fear towards humans.
Volcanic activity, earthquakes, loss of habitat, fire, loss of prey due to poaching, tourism, and illegal poaching of the dragons themselves have all contributed to the vulnerable status of the Komodo dragon. Under Appendix I of CITES (the Convention on International Trade in Endangered Species), commercial trade of skins or specimens is illegal.
On Padar, a former population of the Komodo dragon became extinct, of which the last individuals were seen in 1975. It is widely assumed that the Komodo dragon died out on Padar after a strong decline of the populations of large ungulate prey, for which poaching was most likely responsible.
IN CAPTIVITY
Komodo dragons have long been great zoo attractions, where their size and reputation make them popular exhibits. They are, however, rare in zoos because they are susceptible to infection and parasitic disease if captured from the wild, and do not readily reproduce. As of May 2009, there were 13 European, 2 African, 35 North American, 1 Singaporean, and 2 Australian institutions that kept Komodo dragons.
The first Komodo dragons were displayed at London Zoo in 1927. A Komodo dragon was exhibited in 1934 at the National Zoo in Washington, D.C., but it lived for only two years. More attempts to exhibit Komodo dragons were made, but the lifespan of these animals was very short, averaging five years in the National Zoological Park. Studies done by Walter Auffenberg, which were documented in his book The Behavioral Ecology of the Komodo Monitor, eventually allowed for more successful managing and reproducing of the dragons in captivity.
A variety of behaviors have been observed from captive specimens. Most individuals are relatively tame within a short time, and are capable of recognizing individual humans and discriminating between familiar keepers. Komodo dragons have also been observed to engage in play with a variety of objects, including shovels, cans, plastic rings, and shoes. This behavior does not seem to be "food-motivated predatory behavior".
Even seemingly docile dragons may become unpredictably aggressive, especially when the animal's territory is invaded by someone unfamiliar. In June 2001, a Komodo dragon seriously injured Phil Bronstein, the then husband of actress Sharon Stone, when he entered its enclosure at the Los Angeles Zoo after being invited in by its keeper. Bronstein was bitten on his bare foot, as the keeper had told him to take off his white shoes and socks, which the keeper stated could potentially excite the Komodo dragon as they were the same color as the white rats the zoo fed the dragon. Although he escaped, Bronstein needed to have several tendons in his foot reattached surgically.
IN POPULARE CULTURE
Komodo dragons are used as a main theme in Komodo (1999), Curse of the Komodo (2004) and Komodo vs. Cobra (2005).
The comedy team of Bob and Ray performed a popular sketch entitled "The Komodo Dragon Expert."
The plot of the 1990 film, The Freshman, involves a university freshman, an aging mobster and a Komodo dragon.
In the 2012 James Bond film Skyfall, one of the Chinese henchmen in a casino that Bond visits in Macau is overtaken, dragged off and presumably killed by a Komodo dragon.
WIKIPEDIA
The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang, and Padar. A member of the monitor lizard family Varanidae, it is the largest living species of lizard, growing to a maximum length of 3 metres in rare cases and weighing up to approximately 70 kilograms.

In the wild, an adult Komodo dragon usually weighs around 70 kg, although captive specimens often weigh more. According to the Guinness Book of World Records, an average adult male will weigh 79 to 91 kg and measure 2.59 m, while an average female will weigh 68 to 73 kg and measure 2.29 m. The largest verified wild specimen was 3.13 m long and weighed 166 kg, including undigested food. The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm in length. Its saliva is frequently blood-tinged, because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding.

A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully, the tree is knocked down. To prevent itself from suffocating while swallowing, it breathes using a small tube under the tongue that connects to the lungs. After eating up to 80% of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested for too long. Because of their slow metabolism, large dragons can survive on as little as 12 meals a year. After digestion, the Komodo dragon regurgitates a mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus, suggesting, like humans, it does not relish the scent of its own excretions.
The largest animals eat first, while the smaller ones follow a hierarchy. The largest male asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses. Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors.
The Komodo dragon's diet is wide-ranging, and includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boar, goats, deer, horses, and water buffalo. Young Komodos will eat insects, eggs, geckos, and small mammals. Occasionally, they consume humans and human corpses, digging up bodies from shallow graves. This habit of raiding graves caused the villagers of Komodo to move their graves from sandy to clay ground and pile rocks on top of them to deter the lizards. The Komodo dragon may have evolved to feed on the extinct dwarf elephant Stegodon that once lived on Flores, according to evolutionary biologist Jared Diamond.
The Komodo dragon drinks by sucking water into its mouth via buccal pumping (a process also used for respiration), lifting its head, and letting the water run down its throat.
SALIVA
Auffenberg described the Komodo dragon as having septic pathogens in its saliva (he described the saliva as "reddish and copious"), specifically the bacteria E. coli, Staphylococcus sp., Providencia sp., Proteus morgani, and P. mirabilis. He noted, while these pathogens can be found in the mouths of wild Komodo dragons, they disappear from the mouths of captive animals, due to cleaner diets and the use of antibiotics. This was verified by taking mucous samples from the external gum surfaces of the upper jaws of two freshly captured individuals. Saliva samples were analyzed by researchers at the University of Texas, who found 57 strains of bacteria growing in the mouths of three wild Komodo dragons, including Pasteurella multocida. The rapid growth of these bacteria was noted by Fredeking: "Normally it takes about three days for a sample of P. multocida to cover a Petri dish; ours took eight hours. We were very taken aback by how virulent these strains were". This study supported the observation that wounds inflicted by the Komodo dragon are often associated with sepsis and subsequent infections in prey animals. How the Komodo dragon is unaffected by these virulent bacteria remains a mystery.Research in 2013 suggested that the bacteria in the mouths of komodo dragons are ordinary and similar to those found in other carnivores. They actually have surprisingly good mouth hygiene. As Bryan Fry put it: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in the leaves to clean their mouth... Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria." The observation of prey dying of sepsis would then be explained by the natural instinct of water buffalos, who are not native to the islands where the Komodo dragon lives, to run into water when attacked. The warm, feces filled water would then cause the infections. The study used samples from 16 captive dragons (10 adults and six neonates) from three U.S. zoos.
VENOM
In late 2005, researchers at the University of Melbourne speculated the perentie (Varanus giganteus), other species of monitors, and agamids may be somewhat venomous. The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor (V. varius), a Komodo dragon, and a spotted tree monitor (V. scalaris) all produced similar effects: rapid swelling, localized disruption of blood clotting, and shooting pain up to the elbow, with some symptoms lasting for several hours.
In 2009, the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw. The researchers extracted one of these glands from the head of a terminally ill specimen in the Singapore Zoological Gardens, and found it secreted several different toxic proteins. The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and the induction of hypothermia, leading to shock and loss of consciousness in envenomated prey. As a result of the discovery, the previous theory that bacteria were responsible for the deaths of Komodo victims was disputed.
Kurt Schwenk, an evolutionary biologist at the University of Connecticut, finds the discovery of these glands intriguing, but considers most of the evidence for venom in the study to be "meaningless, irrelevant, incorrect or falsely misleading". Even if the lizards have venom-like proteins in their mouths, Schwenk argues, they may be using them for a different function, and he doubts venom is necessary to explain the effect of a Komodo dragon bite, arguing that shock and blood loss are the primary factors.
Other scientists such as Washington State University's Biologist Kenneth V. Kardong and Toxicologists Scott A. Weinstein and Tamara L. Smith, have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced a very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution". According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey". These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses the biological assessment of squamate biochemical systems".
REPRODUCTION
Mating occurs between May and August, with the eggs laid in September. During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during the early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking. Copulation occurs when the male inserts one of his hemipenes into the female's cloaca. Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards. Female Komodos lay their eggs from August to September and may use several types of locality; in one study, 60% laid their eggs in the nests of orange-footed scrubfowl (a moundbuilder or megapode), 20% on ground level and 20% in hilly areas. The females make many camouflage nests/holes to prevent other dragons from eating the eggs. Clutches contain an average of 20 eggs, which have an incubation period of 7–8 months. Hatching is an exhausting effort for the neonates, which break out of their eggshells with an egg tooth that falls off soon after. After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation. Sixteen youngsters from a single nest were on average 46.5 cm long and weighed 105.1 grams. Young Komodo dragons spend much of their first few years in trees, where they are relatively safe from predators, including cannibalistic adults, as juvenile dragons make up 10% of their diets. The habit of cannibalism may be advantageous in sustaining the large size of adults, as medium-sized prey on the islands is rare. When the young approach a kill, they roll around in fecal matter and rest in the intestines of eviscerated animals to deter these hungry adults. Komodo dragons take approximately three to five years to mature, and may live for up to 50 years.
PARTHENOGENESIS
A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late 2005 after being separated from male company for more than two years. Scientists initially assumed she had been able to store sperm from her earlier encounter with a male, an adaptation known as superfecundation. On 20 December 2006, it was reported that Flora, a captive Komodo dragon living in the Chester Zoo in England, was the second known Komodo dragon to have laid unfertilized eggs: she laid 11 eggs, and seven of them hatched, all of them male. Scientists at Liverpool University in England performed genetic tests on three eggs that collapsed after being moved to an incubator, and verified Flora had never been in physical contact with a male dragon. After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. On 31 January 2008, the Sedgwick County Zoo in Wichita, Kansas, became the first zoo in the Americas to document parthenogenesis in Komodo dragons. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19–20 May 2007. Only two eggs were incubated and hatched due to space issues; the first hatched on 31 January 2008, while the second hatched on 1 February. Both hatchlings were males.
Komodo dragons have the ZW chromosomal sex-determination system, as opposed to the mammalian XY system. Male progeny prove Flora's unfertilized eggs were haploid (n) and doubled their chromosomes later to become diploid (2n) (by being fertilized by a polar body, or by chromosome duplication without cell division), rather than by her laying diploid eggs by one of the meiosis reduction-divisions in her ovaries failing. When a female Komodo dragon (with ZW sex chromosomes) reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes. This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ (male); those receiving a W chromosome become WW and fail to develop, meaning that only males are produced by parthenogenesis in this species.
It has been hypothesized that this reproductive adaptation allows a single female to enter an isolated ecological niche (such as an island) and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population (via reproduction with her offspring that can result in both male and female young). Despite the advantages of such an adaptation, zoos are cautioned that parthenogenesis may be detrimental to genetic diversity.
HISTORY
DISCOVERY BY THE WESTERN WORLD
Komodo dragons were first documented by Europeans in 1910, when rumors of a "land crocodile" reached Lieutenant van Steyn van Hensbroek of the Dutch colonial administration. Widespread notoriety came after 1912, when Peter Ouwens, the director of the Zoological Museum at Bogor, Java, published a paper on the topic after receiving a photo and a skin from the lieutenant, as well as two other specimens from a collector. The first two live Komodo dragons to arrive in Europe were exhibited in the Reptile House at London Zoo when it opened in 1927. Joan Beauchamp Procter made some of the earliest observations of these animals in captivity and she demonstrated the behaviour of one of these animals at a Scientific Meeting of the Zoological Society of London in 1928. The Komodo dragon was the driving factor for an expedition to Komodo Island by W. Douglas Burden in 1926. After returning with 12 preserved specimens and 2 live ones, this expedition provided the inspiration for the 1933 movie King Kong. It was also Burden who coined the common name "Komodo dragon." Three of his specimens were stuffed and are still on display in the American Museum of Natural History.
STUDIES
The Dutch, realizing the limited number of individuals in the wild, outlawed sport hunting and heavily limited the number of individuals taken for scientific study. Collecting expeditions ground to a halt with the occurrence of World War II, not resuming until the 1950s and 1960s, when studies examined the Komodo dragon's feeding behavior, reproduction, and body temperature. At around this time, an expedition was planned in which a long-term study of the Komodo dragon would be undertaken. This task was given to the Auffenberg family, who stayed on Komodo Island for 11 months in 1969. During their stay, Walter Auffenberg and his assistant Putra Sastrawan captured and tagged more than 50 Komodo dragons. The research from the Auffenberg expedition would prove to be enormously influential in raising Komodo dragons in captivity. Research after that of the Auffenberg family has shed more light on the nature of the Komodo dragon, with biologists such as Claudio Ciofi continuing to study the creatures.
CONSERVATION
The Komodo dragon is a vulnerable species and is on the IUCN Red List. There are approximately 4,000 to 5,000 living Komodo dragons in the wild. Their populations are restricted to the islands of Gili Motang (100), Gili Dasami (100), Rinca (1,300), Komodo (1,700), and Flores (perhaps 2,000). However, there are concerns that there may presently be only 350 breeding females. To address these concerns, the Komodo National Park was founded in 1980 to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar. Later, the Wae Wuul and Wolo Tado Reserves were opened on Flores to aid with Komodo dragon conservation.
Komodo dragons avoid encounters with humans. Juveniles are very shy and will flee quickly into a hideout if a human comes closer than about 100 metres. Older animals will also retreat from humans from a shorter distance away. If cornered, they will react aggressively by gaping their mouth, hissing, and swinging their tail. If they are disturbed further, they may start an attack and bite. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or caused by defensive bites. Only a very few cases are truly the result of unprovoked attacks by abnormal individuals, which lost their fear towards humans.
Volcanic activity, earthquakes, loss of habitat, fire, loss of prey due to poaching, tourism, and illegal poaching of the dragons themselves have all contributed to the vulnerable status of the Komodo dragon. Under Appendix I of CITES (the Convention on International Trade in Endangered Species), commercial trade of skins or specimens is illegal.
On Padar, a former population of the Komodo dragon became extinct, of which the last individuals were seen in 1975. It is widely assumed that the Komodo dragon died out on Padar after a strong decline of the populations of large ungulate prey, for which poaching was most likely responsible.
IN CAPTIVITY
Komodo dragons have long been great zoo attractions, where their size and reputation make them popular exhibits. They are, however, rare in zoos because they are susceptible to infection and parasitic disease if captured from the wild, and do not readily reproduce. As of May 2009, there were 13 European, 2 African, 35 North American, 1 Singaporean, and 2 Australian institutions that kept Komodo dragons.
The first Komodo dragons were displayed at London Zoo in 1927. A Komodo dragon was exhibited in 1934 at the National Zoo in Washington, D.C., but it lived for only two years. More attempts to exhibit Komodo dragons were made, but the lifespan of these animals was very short, averaging five years in the National Zoological Park. Studies done by Walter Auffenberg, which were documented in his book The Behavioral Ecology of the Komodo Monitor, eventually allowed for more successful managing and reproducing of the dragons in captivity.
A variety of behaviors have been observed from captive specimens. Most individuals are relatively tame within a short time, and are capable of recognizing individual humans and discriminating between familiar keepers. Komodo dragons have also been observed to engage in play with a variety of objects, including shovels, cans, plastic rings, and shoes. This behavior does not seem to be "food-motivated predatory behavior".
Even seemingly docile dragons may become unpredictably aggressive, especially when the animal's territory is invaded by someone unfamiliar. In June 2001, a Komodo dragon seriously injured Phil Bronstein, the then husband of actress Sharon Stone, when he entered its enclosure at the Los Angeles Zoo after being invited in by its keeper. Bronstein was bitten on his bare foot, as the keeper had told him to take off his white shoes and socks, which the keeper stated could potentially excite the Komodo dragon as they were the same color as the white rats the zoo fed the dragon. Although he escaped, Bronstein needed to have several tendons in his foot reattached surgically.
IN POPULARE CULTURE
Komodo dragons are used as a main theme in Komodo (1999), Curse of the Komodo (2004) and Komodo vs. Cobra (2005).
The comedy team of Bob and Ray performed a popular sketch entitled "The Komodo Dragon Expert."
The plot of the 1990 film, The Freshman, involves a university freshman, an aging mobster and a Komodo dragon.
In the 2012 James Bond film Skyfall, one of the Chinese henchmen in a casino that Bond visits in Macau is overtaken, dragged off and presumably killed by a Komodo dragon.

Arabian camel (Camelus dromedarius) is a large even-toed ungulate with one hump on its back. Its native range is unclear, but it was probably the Arabian Peninsula. The domesticated form occurs widely in North Africa and the Middle East; the world's only population of dromedaries exhibiting wild behaviour is an introduced feral population in Australia.
The dromedary camel is a member of the camel family. Other members of the camel family include the llama and the alpaca in South America. The Dromedary has one hump on its back, in contrast to the Bactrian camel which has two.
Adult males grow to a height of 1.8–2.0 m, and females to 1.7–1.9 m. The weight is usually in the range of 400–600 kg for males, with females being 10% lighter. They show remarkable adaptability in body temperature, from 34 °C to 41.7 °C, this being an adaptation to conserve water.
Male dromedaries have a soft palate, which they inflate to produce a deep pink sack, which is often mistaken for a tongue, called a doula in Arabic, hanging out of the sides of their mouth to attract females during the mating season. Dromedaries are also noted for their thick eyelashes and small, hairy ears.
Dromedaries were first domesticated in central or southern Arabia some thousands of years ago. Experts are divided regarding the date: some believe it was around 4000 BC, others as recently as 1400 BC. There are currently almost 13 million domesticated dromedaries, mostly in the area from Western India via Pakistan through Iran to northern Africa. None survive in the wild in their original range, although the escaped population of Australian feral camels is estimated to number at least 300,000 and possibly over 1 million. Around the second millennium BC, the dromedary was introduced to Egypt and North Africa. In the Canary Islands, the dromedaries were introduced recently as domestic animals.
Although there are several other camelids, the only other surviving species of true wild camel today is the Bactrian Camel. The Bactrian camel was domesticated sometime before 2500 BC in Asia, well after the earliest estimates for the dromedary. The Bactrian camel is a stockier, hardier animal, being able to survive from Iran to Tibet. The dromedary is taller and faster: with a rider they can maintain 8-9 mph (13-14.5 km/h) for hours at a time. By comparison, a loaded Bactrian camel moves at about 2.5 mph (4 km/h).

Thank you to the vast majority of fans last night for your excellent behaviour while watching the England game.
Although the score didn’t go our way, fans by-and-large were brilliant and watched the #WorldCup semi-final between England and Croatia in good spirits.
Nine arrests were made in total in Manchester City Centre including public order offences and being drunk and disorderly, but thankfully no serious incidents took place.
We would also like to thank all the officers who worked hard to keep everyone safe last night, with many having to give up their plans of watching the game with friends and family.
Yesterday was a testament to fans – you came together, helped look after each other and dealt with the result graciously.
Bring on Euro 2020!

In my opinion, our local street cleaners - working for Veolia - do a good job; collecting and bagging waste in the company's purple bags.
Which are supposed to be collected reasonably quickly.
But while the "official" bags await collection, they act like a "magnet" - tacitly encouraging a few people to add their own waste bags to the pile.
Governments around the world are drawing on behavioural insights to improve public policy outcomes: from automatic enrolment for pensions, to better tax compliance, to increasing the supply of organ donation.
But those very same policy makers are also subject to biases that can distort decision making. The Behavioural Insights Team has been studying those biases and what can be done to counter them, in collaboration with Jill Rutter and Julian McCrae of the Institute for Government.
The report was launched with remarks from Alex Chisholm, Permanent Secretary at the Department for Business, Energy, and Industrial Strategy.
Dr Michael Hallsworth, Director of the Behavioural Insights Team in North America presented the key findings.
The findings, their relevance to policy making today, and what they mean for the way governments make decisions were discussed by:
Polly Mackenzie, Director of Policy for the Deputy Prime Minister, 2010–15 and now Director of Demos
Dr Tony Curzon Price, Economic Advisor to the Secretary of State for Business, Energy and Industrial Strategy.
The event was chaired by Jill Rutter, Programme Director at the Institute for Government.
