According to the online information,
there are some evidence that a full moon may lead to less sleep, a slight change in cardiovascular conditions, traffic accidents, crimes, violences and suicides, and it may also effect human reproduction, in particular fertility, menstruation and birth rate.
As the moon comes closer to the Earth, gravitational pull gets stronger ,and we see higher tides.
Up to 60% of our body is water (in adults), the content of the water is not same in each of our organs. The changing gravitational pull might also affect how water react inside of our body.
I don't think that we have just negative effects from a full moon, we may experience some positive effects like a higher level of creativity , a higher intelligence level, etc.
Need to get a checkup? In Chinatown, no need to even go in the building, or pay. The doctor will wait for you on the street and give you a free consultation (and upsell, I'm sure!!!) The sign says "免费检测心血管功能" which literally translates "Free Detection of Cardiovascular Function." Or I guess the best translation would be "Free Cardiovascular Checkup." Especially funny I think is the woman walking by the face mask!
My Chinatown series has returned!
Quick question regarding that self portrait i posted. Who thinks I should really do more of that stuff ....... Or should I just stick to what I am more comfortable with. I guess a dumb question, but still. Any words of wisdom?
Scientific research has explored grounding for inflammation, cardiovascular disease, muscle damage, chronic pain, and mood.
The central theory from one review studyTrusted Source is that grounding affects the living matrix, which is the central connector between living cells.
Electrical conductivity exists within the matrix that functions as an immune system defense, similar to antioxidants. They believe that through grounding, the natural defenses of the body can be restored. Further research expands on this idea.
In a small studyTrusted Source on grounding and heart health, 10 healthy participants were grounded using patches on the palms of their hands and soles of their feet.
Blood measurements were taken before and after grounding to determine any changes in red blood cell fluidity, which plays a role in heart health. The results indicated significantly less red blood cell clumping after grounding, which suggests benefits for cardiovascular health.
Another slightly larger studyTrusted Source examined the role of grounding on post-exercise muscle damage. Researchers used both grounding patches and mats and measured creatine kinase, white blood cell count, and pain levels before and after grounding.
Blood work indicated that grounding reduced muscle damage and pain in participants. This suggests that grounding may influence healing abilities.
This research is supported by a recent studyTrusted Source on grounding for pain reduction and mood improvement. Sixteen massage therapists alternated between periods of grounding and no grounding.
Before grounding therapy, physical and emotional stress and pain were common side effects of their physically demanding jobs. After the earthing therapy, pain, stress, depression, and fatigue were all reduced among participants.
Most of the studies on grounding are small and rely somewhat on subjective measures, such as self-reported feelings, mood, or even self-administered treatment.
Some studies also rely on blood markers, such as those that detect inflammation, but the size and shortage of these studies suggests that more research is needed.
Types of grounding or earthing
There are many types of grounding. All of them focus on reconnecting yourself to the earth. This can be done through either direct or indirect contact with the earth.
Walking barefoot
Have you ever been outside on a warm summer day and felt the urge to run barefoot in the grass? One of the easiest ways to ground yourself to the earth is to walk barefoot.
Whether this is on grass, sand, or even mud, allowing your skin to touch the natural ground can provide you with grounding energy.
Lying on the ground
You can increase your skin-to-earth contact by lying on the ground. You can do it in the grass by the park or on the sand at the beach.
If you’re going to ground yourself in this way, be sure to take the proper precautions and never lie somewhere you could be injured.
Submersing in water
According to advocates for grounding, water may be used to ground in the same way the physical earth is used for grounding.
They suggest simply wading in a clear lake or swimming in the ocean as a way to ground yourself. As always, be sure to stay safe when swimming, especially in murky or deep waters.
Using grounding equipment
When going outside to ground yourself isn’t an option, there are alternativesTrusted Source. One method of earthing involves connecting a metal rod to the ground outside and then connecting the rod to your body through a wire.
If you’re not comfortable using a metal rod to ground yourself, there’s other grounding equipment available. This equipment is an effective way to incorporate earthing therapy into your daily life and includes:
grounding mats
grounding sheets or blankets
grounding socks
grounding bands and patches
You can find grounding mats, sheets, blankets, socks, and bands online.

The last two days have been spent at home, with sore eyes from the wildfire smoke that continues to blow in from British Columbia. Today, 18 August 2018, the Air Quality was at 10+ again, which is the worst level.
"With such poor air quality, the federal weather authority is warning those most at risk, including children, seniors and people with cardiovascular or respiratory illness. They're encouraged to avoid strenuous outdoor activities entirely." From CBC News, 18 August 2018.
On 15 and 16 August 2018, Calgary's AIR QUALITY hit 10 and 10+, the worst possible rating, as wildfire smoke blankets Alberta. The smoke blown from the BC wildfires is intensely unpleasant - no sign of the mountains and we can barely even see the foothills, the smoke is so thick. Not just unpleasant outside, but I can also smell the smoke inside my home. I really, really hope BC gets some heavy rain as soon as possible, giving the brave firefighters a break and preventing even more loss, of lives, homes, wildlife and forest.

The day before yesterday, 16 August 2018, I was invited to go with a friend to visit a mutual friend down in Turner Valley and see the birds that come to her beautiful back garden. Only small, this area has been so thoughtfully and beautifully laid out, encouraging all sorts of birds and other wildlife to visit. She is so fortunate that a wildlife corridor is just beyond her deck and garden. Totally unexpectedly, Jackie made us a delicious cheese bun sandwich for lunch that included tomatoes she has grown herself on her deck, along with cold, refreshing lemonade. Thank you so much, Jackie, for your kindness, as always!
Pam, I really appreciate your invite to go with you, and thanks so much for driving a few new back roads and a stop at Frank Lake. I don't know where all the birds were, but there were so few at the Lake and most of those were far, far out. It was a real treat, though, to start off our morning with a beautiful Swainson's Hawk that was perched on a fence post, and to end our day with several (was it three?) American White Pelicans in flight and then landing on a pond in the city. We were lucky that one of them was still on the water by the time we had parked and walked to the pond.
Despite the thick blanket of smoke everywhere and the dreadful air quality, the faint landscape that surrounded us was eerily beautiful. It will feel almost strange to see our beautiful foothills and mountains once again, when the wildfire smoke finally comes to an end.
Smoking kills! Its a reason for: Respiratory diseases, cardiovascular diseases, including heart disease, stroke and diseases of the blood vessels can often be traced back to smoking. Keeping aside these big shot ailments, smoking also causes cataracts, impotency, infertility, menstrual disorders, sleeping problems, thyroid disease, tooth and gum disease, ulcers and even bowel disorders.
Despite repeated warnings many of us fail to recognize the true danger associated with smoking, we must be able to check temptation at the door and rid ourselves of this killer habit. Quit smoking and encourage a healthier world.
I have nothing against smokers, its life choice...its just awareness day :) How ever, Im a proud non smoker :)
This morning, 18 August 2018, the Air Quality Health Index in Calgary was listed at 10+ — or very high risk, the highest possible rating.

Posting these four photos late tonight, just in case I decide to go on an outing with friends to Kananaskis tomorrow. If I go, it will mean an extremely early start, like 5:00 am. Not sure I really feel like doing that, so it probably won't happen. Next morning - no, decided not to go. Also, our air quality today is again at 10, the highest level of poor quality.

this is my friend Eva - a fantastic artist and even more amazing person. this was done for a photo contest at my medical school titled "heartfelt images". we're doing the cardiovascular system, and the block chair loves art in science.
we had planned on doing a shoot together, but it was coincidence that Eva had her facepainting kit in her trunk. she painted this on herself with a laptop and a mirror. not bad!
I tried to get all fancy with this shot and do something clever with shadows. It didn't work, but it doesn't matter, because the message is simple and so should the shot be...Go red this February and join in the fun for National Heart Month.
2011 is the British Heart Foundation's 50th birthday, so what better time to join the celebrations? Get involved in Red for Heart to help raise funds for their vital work.
The BHF is the nation's heart charity. Their vision is a world where people don't die prematurely from heart disease.
They look to achieve this through pioneering research, vital prevention activity and ensuring quality care and support for everyone living with heart disease.
There's lots you can do to keep your heart healthy - whatever your age.
Taking exercise, eating a healthy diet, encouraging children to be heart healthy and being aware of dangers such as smoking, drinking, high blood pressure and stress.
Prevention really is better than cure. People of all ages who are physically active are half as likely to get cardiovascular disease as those that are inactive.And a healthy diet helps to reduce your risk of developing heart disease, or if you've already got heart problems it will help to protect your heart.
Think about your heart health and what you can do to keep as healthy as possible.

A new study into the potential of artificial gravity to help astronauts stay healthy in space is now in full swing, or should that be spin?
Phase one of the 60-day bedrest study, commissioned by ESA and NASA and carried out by German Aerospace Center DLR, began at DLR’s ‘:envihab’ medical research and rehabilitation facility in Cologne, Germany, on Monday 25 March.
The study is the first of its kind to be conducted in partnership between ESA and NASA. It is also the first to employ DLR’s short-arm centrifuge (shown in this image) as a way of recreating gravity for participants.
Each of the 12 male and 12 female participants will lie in beds with their heads tilted 6° below horizontal for 60 consecutive days. Medical researchers will oversee them and ensure one of their shoulders is touching the mattress at all times.
As blood flows to their heads and muscle is lost from underuse, researchers will investigate changes and test techniques from diet to physical exercise.
Artificial gravity is one of the techniques under the spotlight this time around. Once a day, a selection of the study’s participants will be moved to the centrifuge to encourage blood to flow back towards their feet and allow researchers to understand the potential of artificial gravity in combating the effects of weightlessness.
A number of different experiments, carried out over the course of the study, will look at cardiovascular function, balance and muscle strength, metabolism and cognitive performance among other factors.
Seven of these experiments will be conducted by European-led research groups, with a view to validating the findings on the International Space Station during future missions.

The Easter Island cemetery is unique in many ways. Some of the tombstones are adorned with motifs that combine Christian and Rapa Nui iconography.
There are no good records in what year burials are made, as it is not customary to write the date of death.
On the island there is a belief that when there is a series of very frequent deaths of elderly people, they will not stop until a child or young person dies.
Funerals are held in the Church of Santa Cruz and then the funeral procession accompanies the coffin to reach the cemetery.
On Easter Island (Rapa Nui), with approximately 5,600 inhabitants and 25 deaths during 2012. The most common cause of death are cardiovascular accidents, the sick are often transferred to Santiago in Chile. When the patient dies in the capital, his remains are transferred to the island.
There are no funeral companies on the island, so the relatives have to take care of all details of the funeral, from the construction of the coffin to the transfer to the cemetery.
There it is. A black line printed out on a sheet of paper. A line that shows the direction that my life runs, and all the peaks and crests that go with it. The doctor called to say that my heart is fine. I had noticed it beating in an aberrant rhythm a few weeks ago, and it had me worried enough. I'm just not used to having such a vital organ kick up such a fuss. The doctor was a wrinkled old man, a Southerner from tip to toe. He smelled, disconcertingly, of a nightclub at closing hour. This despite the fact that he had come highly recommended by a couple of friends. He casually studied at my EKG readout while I told him about my heart palpitations. A few minutes later I found myself lying on the examining table, with him pushing his chilly stethoscope all over my bare chest. I know this is what doctors do, but all things being equal, it's still really disconcerting to have a complete stranger touch you in this way. We waited together there for my heart to perform its curious palpitation under his listening ear. His hands and stethoscope wandered through the lands while I lay there cringing. Finally as his hand snuck around to cup my left breast, the heart backflip happened — yes, there it is! he said, brightening...
But he called to say that it's fine, and that I'm as healthy as a teenager. Which was meant to make me feel good, I guess, but mostly made me cringe again.

Sheep (pl.: sheep) or domestic sheep (Ovis aries) are a domesticated, ruminant mammal typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (/juː/ yoo), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonwealth countries, ovine meat is called lamb when from younger animals and mutton when from older ones; in the United States, meat from both older and younger animals is usually called lamb. Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science.
Sheep husbandry is practised throughout the majority of the inhabited world, and has been fundamental to many civilizations. In the modern era, Australia, New Zealand, the southern and central South American nations, and the British Isles are most closely associated with sheep production.
There is a large lexicon of unique terms for sheep husbandry which vary considerably by region and dialect. Use of the word sheep began in Middle English as a derivation of the Old English word scēap. A group of sheep is called a flock. Many other specific terms for the various life stages of sheep exist, generally related to lambing, shearing, and age.
Being a key animal in the history of farming, sheep have a deeply entrenched place in human culture, and are represented in much modern language and symbolism. As livestock, sheep are most often associated with pastoral, Arcadian imagery. Sheep figure in many mythologies—such as the Golden Fleece—and major religions, especially the Abrahamic traditions. In both ancient and modern religious ritual, sheep are used as sacrificial animals.
History
Main article: History of the domestic sheep
The exact line of descent from wild ancestors to domestic sheep is unclear. The most common hypothesis states that Ovis aries is descended from the Asiatic (O. gmelini) species of mouflon; the European mouflon (Ovis aries musimon) is a direct descendant of this population. Sheep were among the first animals to be domesticated by humankind (although the domestication of dogs probably took place 10 to 20 thousand years earlier); the domestication date is estimated to fall between 11,000 and 9000 B.C in Mesopotamia and possibly around 7000 BC in Mehrgarh in the Indus Valley. The rearing of sheep for secondary products, and the resulting breed development, began in either southwest Asia or western Europe. Initially, sheep were kept solely for meat, milk and skins. Archaeological evidence from statuary found at sites in Iran suggests that selection for woolly sheep may have begun around 6000 BC, and the earliest woven wool garments have been dated to two to three thousand years later.
Sheep husbandry spread quickly in Europe. Excavations show that in about 6000 BC, during the Neolithic period of prehistory, the Castelnovien people, living around Châteauneuf-les-Martigues near present-day Marseille in the south of France, were among the first in Europe to keep domestic sheep. Practically from its inception, ancient Greek civilization relied on sheep as primary livestock, and were even said to name individual animals. Ancient Romans kept sheep on a wide scale, and were an important agent in the spread of sheep raising. Pliny the Elder, in his Natural History (Naturalis Historia), speaks at length about sheep and wool. European colonists spread the practice to the New World from 1493 onwards.
Characteristics
Domestic sheep are relatively small ruminants, usually with a crimped hair called wool and often with horns forming a lateral spiral. They differ from their wild relatives and ancestors in several respects, having become uniquely neotenic as a result of selective breeding by humans. A few primitive breeds of sheep retain some of the characteristics of their wild cousins, such as short tails. Depending on breed, domestic sheep may have no horns at all (i.e. polled), or horns in both sexes, or in males only. Most horned breeds have a single pair, but a few breeds may have several.
Sheep in Turkmenistan
Another trait unique to domestic sheep as compared to wild ovines is their wide variation in color. Wild sheep are largely variations of brown hues, and variation within species is extremely limited. Colors of domestic sheep range from pure white to dark chocolate brown, and even spotted or piebald. Sheep keepers also sometimes artificially paint "smit marks" onto their sheep in any pattern or color for identification. Selection for easily dyeable white fleeces began early in sheep domestication, and as white wool is a dominant trait it spread quickly. However, colored sheep do appear in many modern breeds, and may even appear as a recessive trait in white flocks. While white wool is desirable for large commercial markets, there is a niche market for colored fleeces, mostly for handspinning. The nature of the fleece varies widely among the breeds, from dense and highly crimped, to long and hairlike. There is variation of wool type and quality even among members of the same flock, so wool classing is a step in the commercial processing of the fibre.
Suffolks are a medium wool, black-faced breed of meat sheep that make up 60% of the sheep population in the U.S.
Depending on breed, sheep show a range of heights and weights. Their rate of growth and mature weight is a heritable trait that is often selected for in breeding. Ewes typically weigh between 45 and 100 kilograms (100 and 220 lb), and rams between 45 and 160 kilograms (100 and 350 lb). When all deciduous teeth have erupted, the sheep has 20 teeth. Mature sheep have 32 teeth. As with other ruminants, the front teeth in the lower jaw bite against a hard, toothless pad in the upper jaw. These are used to pick off vegetation, then the rear teeth grind it before it is swallowed. There are eight lower front teeth in ruminants, but there is some disagreement as to whether these are eight incisors, or six incisors and two incisor-shaped canines. This means that the dental formula for sheep is either
0.0.3.3
4.0.3.3
or
0.0.3.3
3.1.3.3
There is a large diastema between the incisors and the molars.
In the first few years of life one can calculate the age of sheep from their front teeth, as a pair of milk teeth is replaced by larger adult teeth each year, the full set of eight adult front teeth being complete at about four years of age. The front teeth are then gradually lost as sheep age, making it harder for them to feed and hindering the health and productivity of the animal. For this reason, domestic sheep on normal pasture begin to slowly decline from four years on, and the life expectancy of a sheep is 10 to 12 years, though some sheep may live as long as 20 years.
Skull
Sheep have good hearing, and are sensitive to noise when being handled. Sheep have horizontal slit-shaped pupils, with excellent peripheral vision; with visual fields of about 270° to 320°, sheep can see behind themselves without turning their heads. Many breeds have only short hair on the face, and some have facial wool (if any) confined to the poll and or the area of the mandibular angle; the wide angles of peripheral vision apply to these breeds. A few breeds tend to have considerable wool on the face; for some individuals of these breeds, peripheral vision may be greatly reduced by "wool blindness", unless recently shorn about the face. Sheep have poor depth perception; shadows and dips in the ground may cause sheep to baulk. In general, sheep have a tendency to move out of the dark and into well-lit areas, and prefer to move uphill when disturbed. Sheep also have an excellent sense of smell, and, like all species of their genus, have scent glands just in front of the eyes, and interdigitally on the feet. The purpose of these glands is uncertain, but those on the face may be used in breeding behaviors. The foot glands might also be related to reproduction, but alternative functions, such as secretion of a waste product or a scent marker to help lost sheep find their flock, have also been proposed.
Comparison with goats
Sheep and goats are closely related: both are in the subfamily Caprinae. However, they are separate species, so hybrids rarely occur and are always infertile. A hybrid of a ewe and a buck (a male goat) is called a sheep-goat hybrid, known as geep. Visual differences between sheep and goats include the beard of goats and divided upper lip of sheep. Sheep tails also hang down, even when short or docked, while the short tails of goats are held upwards. Also, sheep breeds are often naturally polled (either in both sexes or just in the female), while naturally polled goats are rare (though many are polled artificially). Males of the two species differ in that buck goats acquire a unique and strong odor during the rut, whereas rams do not.
Breeds
The domestic sheep is a multi-purpose animal, and the more than 200 breeds now in existence were created to serve these diverse purposes. Some sources give a count of a thousand or more breeds, but these numbers cannot be verified, according to some sources. However, several hundred breeds of sheep have been identified by the Food and Agriculture Organization of the UN (FAO), with the estimated number varying somewhat from time to time: e.g. 863 breeds as of 1993, 1314 breeds as of 1995 and 1229 breeds as of 2006. (These numbers exclude extinct breeds, which are also tallied by the FAO.) For the purpose of such tallies, the FAO definition of a breed is "either a subspecific group of domestic livestock with definable and identifiable external characteristics that enable it to be separated by visual appraisal from other similarly defined groups within the same species or a group for which geographical and/or cultural separation from phenotypically similar groups has led to acceptance of its separate identity." Almost all sheep are classified as being best suited to furnishing a certain product: wool, meat, milk, hides, or a combination in a dual-purpose breed. Other features used when classifying sheep include face color (generally white or black), tail length, presence or lack of horns, and the topography for which the breed has been developed. This last point is especially stressed in the UK, where breeds are described as either upland (hill or mountain) or lowland breeds. A sheep may also be of a fat-tailed type, which is a dual-purpose sheep common in Africa and Asia with larger deposits of fat within and around its tail.
Breeds are often categorized by the type of their wool. Fine wool breeds are those that have wool of great crimp and density, which are preferred for textiles. Most of these were derived from Merino sheep, and the breed continues to dominate the world sheep industry. Downs breeds have wool between the extremes, and are typically fast-growing meat and ram breeds with dark faces. Some major medium wool breeds, such as the Corriedale, are dual-purpose crosses of long and fine-wooled breeds and were created for high-production commercial flocks. Long wool breeds are the largest of sheep, with long wool and a slow rate of growth. Long wool sheep are most valued for crossbreeding to improve the attributes of other sheep types. For example: the American Columbia breed was developed by crossing Lincoln rams (a long wool breed) with fine-wooled Rambouillet ewes.
Coarse or carpet wool sheep are those with a medium to long length wool of characteristic coarseness. Breeds traditionally used for carpet wool show great variability, but the chief requirement is a wool that will not break down under heavy use (as would that of the finer breeds). As the demand for carpet-quality wool declines, some breeders of this type of sheep are attempting to use a few of these traditional breeds for alternative purposes. Others have always been primarily meat-class sheep.
A minor class of sheep are the dairy breeds. Dual-purpose breeds that may primarily be meat or wool sheep are often used secondarily as milking animals, but there are a few breeds that are predominantly used for milking. These sheep produce a higher quantity of milk and have slightly longer lactation curves. In the quality of their milk, the fat and protein content percentages of dairy sheep vary from non-dairy breeds, but lactose content does not.
A last group of sheep breeds is that of fur or hair sheep, which do not grow wool at all. Hair sheep are similar to the early domesticated sheep kept before woolly breeds were developed, and are raised for meat and pelts. Some modern breeds of hair sheep, such as the Dorper, result from crosses between wool and hair breeds. For meat and hide producers, hair sheep are cheaper to keep, as they do not need shearing. Hair sheep are also more resistant to parasites and hot weather.
With the modern rise of corporate agribusiness and the decline of localized family farms, many breeds of sheep are in danger of extinction. The Rare Breeds Survival Trust of the UK lists 22 native breeds as having only 3,000 registered animals (each), and The Livestock Conservancy lists 14 as either "critical" or "threatened". Preferences for breeds with uniform characteristics and fast growth have pushed heritage (or heirloom) breeds to the margins of the sheep industry. Those that remain are maintained through the efforts of conservation organizations, breed registries, and individual farmers dedicated to their preservation.
Diet
Sheep are herbivorous mammals. Most breeds prefer to graze on grass and other short roughage, avoiding the taller woody parts of plants that goats readily consume. Both sheep and goats use their lips and tongues to select parts of the plant that are easier to digest or higher in nutrition. Sheep, however, graze well in monoculture pastures where most goats fare poorly.
Ruminant system of a sheep
Like all ruminants, sheep have a complex digestive system composed of four chambers, allowing them to break down cellulose from stems, leaves, and seed hulls into simpler carbohydrates. When sheep graze, vegetation is chewed into a mass called a bolus, which is then passed into the rumen, via the reticulum. The rumen is a 19- to 38-liter (5 to 10 gallon) organ in which feed is fermented. The fermenting organisms include bacteria, fungi, and protozoa. (Other important rumen organisms include some archaea, which produce methane from carbon dioxide.) The bolus is periodically regurgitated back to the mouth as cud for additional chewing and salivation. After fermentation in the rumen, feed passes into the reticulum and the omasum; special feeds such as grains may bypass the rumen altogether. After the first three chambers, food moves into the abomasum for final digestion before processing by the intestines. The abomasum is the only one of the four chambers analogous to the human stomach, and is sometimes called the "true stomach".
Other than forage, the other staple feed for sheep is hay, often during the winter months. The ability to thrive solely on pasture (even without hay) varies with breed, but all sheep can survive on this diet. Also included in some sheep's diets are minerals, either in a trace mix or in licks. Feed provided to sheep must be specially formulated, as most cattle, poultry, pig, and even some goat feeds contain levels of copper that are lethal to sheep. The same danger applies to mineral supplements such as salt licks.
Grazing behavior
Sheep follow a diurnal pattern of activity, feeding from dawn to dusk, stopping sporadically to rest and chew their cud. Ideal pasture for sheep is not lawnlike grass, but an array of grasses, legumes and forbs. Types of land where sheep are raised vary widely, from pastures that are seeded and improved intentionally to rough, native lands. Common plants toxic to sheep are present in most of the world, and include (but are not limited to) cherry, some oaks and acorns, tomato, yew, rhubarb, potato, and rhododendron.
Effects on pasture
Sheep are largely grazing herbivores, unlike browsing animals such as goats and deer that prefer taller foliage. With a much narrower face, sheep crop plants very close to the ground and can overgraze a pasture much faster than cattle. For this reason, many shepherds use managed intensive rotational grazing, where a flock is rotated through multiple pastures, giving plants time to recover. Paradoxically, sheep can both cause and solve the spread of invasive plant species. By disturbing the natural state of pasture, sheep and other livestock can pave the way for invasive plants. However, sheep also prefer to eat invasives such as cheatgrass, leafy spurge, kudzu and spotted knapweed over native species such as sagebrush, making grazing sheep effective for conservation grazing. Research conducted in Imperial County, California compared lamb grazing with herbicides for weed control in seedling alfalfa fields. Three trials demonstrated that grazing lambs were just as effective as herbicides in controlling winter weeds. Entomologists also compared grazing lambs to insecticides for insect control in winter alfalfa. In this trial, lambs provided insect control as effectively as insecticides.
Behavior
Sheep are flock animals and strongly gregarious; much sheep behavior can be understood on the basis of these tendencies. The dominance hierarchy of sheep and their natural inclination to follow a leader to new pastures were the pivotal factors in sheep being one of the first domesticated livestock species. Furthermore, in contrast to the red deer and gazelle (two other ungulates of primary importance to meat production in prehistoric times), sheep do not defend territories although they do form home ranges. All sheep have a tendency to congregate close to other members of a flock, although this behavior varies with breed, and sheep can become stressed when separated from their flock members. During flocking, sheep have a strong tendency to follow, and a leader may simply be the first individual to move. Relationships in flocks tend to be closest among related sheep: in mixed-breed flocks, subgroups of the same breed tend to form, and a ewe and her direct descendants often move as a unit within large flocks. Sheep can become hefted to one particular local pasture (heft) so they do not roam freely in unfenced landscapes. Lambs learn the heft from ewes and if whole flocks are culled it must be retaught to the replacement animals.
Flock behaviour in sheep is generally only exhibited in groups of four or more sheep; fewer sheep may not react as expected when alone or with few other sheep. Being a prey species, the primary defense mechanism of sheep is to flee from danger when their flight zone is entered. Cornered sheep may charge and butt, or threaten by hoof stamping and adopting an aggressive posture. This is particularly true for ewes with newborn lambs.
In regions where sheep have no natural predators, none of the native breeds of sheep exhibit a strong flocking behavior.
Herding
Farmers exploit flocking behavior to keep sheep together on unfenced pastures such as hill farming, and to move them more easily. For this purpose shepherds may use herding dogs in this effort, with a highly bred herding ability. Sheep are food-oriented, and association of humans with regular feeding often results in sheep soliciting people for food. Those who are moving sheep may exploit this behavior by leading sheep with buckets of feed.
Dominance hierarchy
Sheep establish a dominance hierarchy through fighting, threats and competitiveness. Dominant animals are inclined to be more aggressive with other sheep, and usually feed first at troughs. Primarily among rams, horn size is a factor in the flock hierarchy. Rams with different size horns may be less inclined to fight to establish the dominance order, while rams with similarly sized horns are more so. Merinos have an almost linear hierarchy whereas there is a less rigid structure in Border Leicesters when a competitive feeding situation arises.
In sheep, position in a moving flock is highly correlated with social dominance, but there is no definitive study to show consistent voluntary leadership by an individual sheep.
Intelligence and learning ability
Sheep are frequently thought of as unintelligent animals. Their flocking behavior and quickness to flee and panic can make shepherding a difficult endeavor for the uninitiated. Despite these perceptions, a University of Illinois monograph on sheep reported their intelligence to be just below that of pigs and on par with that of cattle. Sheep can recognize individual human and ovine faces and remember them for years; they can remember 50 other different sheep faces for over two years; they can recognize and are attracted to individual sheep and humans by their faces, as they possess similar specialized neural systems in the temporal and frontal lobes of their brains to humans and have a greater involvement of the right brain hemisphere. In addition to long-term facial recognition of individuals, sheep can also differentiate emotional states through facial characteristics.[68][69] If worked with patiently, sheep may learn their names, and many sheep are trained to be led by halter for showing and other purposes. Sheep have also responded well to clicker training. Sheep have been used as pack animals; Tibetan nomads distribute baggage equally throughout a flock as it is herded between living sites.
It has been reported that some sheep have apparently shown problem-solving abilities; a flock in West Yorkshire, England allegedly found a way to get over cattle grids by rolling on their backs, although documentation of this has relied on anecdotal accounts.
Vocalisations
Sounds made by domestic sheep include bleats, grunts, rumbles and snorts. Bleating ("baaing") is used mostly for contact communication, especially between dam and lambs, but also at times between other flock members. The bleats of individual sheep are distinctive, enabling the ewe and her lambs to recognize each other's vocalizations. Vocal communication between lambs and their dam declines to a very low level within several weeks after parturition. A variety of bleats may be heard, depending on sheep age and circumstances. Apart from contact communication, bleating may signal distress, frustration or impatience; however, sheep are usually silent when in pain. Isolation commonly prompts bleating by sheep. Pregnant ewes may grunt when in labor. Rumbling sounds are made by the ram during courting; somewhat similar rumbling sounds may be made by the ewe, especially when with her neonate lambs. A snort (explosive exhalation through the nostrils) may signal aggression or a warning, and is often elicited from startled sheep.
Lamb
In sheep breeds lacking facial wool, the visual field is wide. In 10 sheep (Cambridge, Lleyn and Welsh Mountain breeds, which lack facial wool), the visual field ranged from 298° to 325°, averaging 313.1°, with binocular overlap ranging from 44.5° to 74°, averaging 61.7°. In some breeds, unshorn facial wool can limit the visual field; in some individuals, this may be enough to cause "wool blindness". In 60 Merinos, visual fields ranged from 219.1° to 303.0°, averaging 269.9°, and the binocular field ranged from 8.9° to 77.7°, averaging 47.5°; 36% of the measurements were limited by wool, although photographs of the experiments indicate that only limited facial wool regrowth had occurred since shearing. In addition to facial wool (in some breeds), visual field limitations can include ears and (in some breeds) horns, so the visual field can be extended by tilting the head. Sheep eyes exhibit very low hyperopia and little astigmatism. Such visual characteristics are likely to produce a well-focused retinal image of objects in both the middle and long distance. Because sheep eyes have no accommodation, one might expect the image of very near objects to be blurred, but a rather clear near image could be provided by the tapetum and large retinal image of the sheep's eye, and adequate close vision may occur at muzzle length. Good depth perception, inferred from the sheep's sure-footedness, was confirmed in "visual cliff" experiments; behavioral responses indicating depth perception are seen in lambs at one day old. Sheep are thought to have colour vision, and can distinguish between a variety of colours: black, red, brown, green, yellow and white. Sight is a vital part of sheep communication, and when grazing, they maintain visual contact with each other. Each sheep lifts its head upwards to check the position of other sheep in the flock. This constant monitoring is probably what keeps the sheep in a flock as they move along grazing. Sheep become stressed when isolated; this stress is reduced if they are provided with a mirror, indicating that the sight of other sheep reduces stress.
Taste is the most important sense in sheep, establishing forage preferences, with sweet and sour plants being preferred and bitter plants being more commonly rejected. Touch and sight are also important in relation to specific plant characteristics, such as succulence and growth form.
The ram uses his vomeronasal organ (sometimes called the Jacobson's organ) to sense the pheromones of ewes and detect when they are in estrus. The ewe uses her vomeronasal organ for early recognition of her neonate lamb.
Reproduction
Sheep follow a similar reproductive strategy to other herd animals. A group of ewes is generally mated by a single ram, who has either been chosen by a breeder or (in feral populations) has established dominance through physical contest with other rams. Most sheep are seasonal breeders, although some are able to breed year-round. Ewes generally reach sexual maturity at six to eight months old, and rams generally at four to six months. However, there are exceptions. For example, Finnsheep ewe lambs may reach puberty as early as 3 to 4 months, and Merino ewes sometimes reach puberty at 18 to 20 months. Ewes have estrus cycles about every 17 days, during which they emit a scent and indicate readiness through physical displays towards rams.
In feral sheep, rams may fight during the rut to determine which individuals may mate with ewes. Rams, especially unfamiliar ones, will also fight outside the breeding period to establish dominance; rams can kill one another if allowed to mix freely. During the rut, even usually friendly rams may become aggressive towards humans due to increases in their hormone levels.
After mating, sheep have a gestation period of about five months, and normal labor takes one to three hours. Although some breeds regularly throw larger litters of lambs, most produce single or twin lambs. During or soon after labor, ewes and lambs may be confined to small lambing jugs, small pens designed to aid both careful observation of ewes and to cement the bond between them and their lambs.
A lamb's first steps
Ovine obstetrics can be problematic. By selectively breeding ewes that produce multiple offspring with higher birth weights for generations, sheep producers have inadvertently caused some domestic sheep to have difficulty lambing; balancing ease of lambing with high productivity is one of the dilemmas of sheep breeding. In the case of any such problems, those present at lambing may assist the ewe by extracting or repositioning lambs. After the birth, ewes ideally break the amniotic sac (if it is not broken during labor), and begin licking clean the lamb. Most lambs will begin standing within an hour of birth. In normal situations, lambs nurse after standing, receiving vital colostrum milk. Lambs that either fail to nurse or are rejected by the ewe require help to survive, such as bottle-feeding or fostering by another ewe.
Most lambs begin life being born outdoors. After lambs are several weeks old, lamb marking (ear tagging, docking, mulesing, and castrating) is carried out. Vaccinations are usually carried out at this point as well. Ear tags with numbers are attached, or ear marks are applied, for ease of later identification of sheep. Docking and castration are commonly done after 24 hours (to avoid interference with maternal bonding and consumption of colostrum) and are often done not later than one week after birth, to minimize pain, stress, recovery time and complications. The first course of vaccinations (commonly anti-clostridial) is commonly given at an age of about 10 to 12 weeks; i.e. when the concentration of maternal antibodies passively acquired via colostrum is expected to have fallen low enough to permit development of active immunity. Ewes are often revaccinated annually about 3 weeks before lambing, to provide high antibody concentrations in colostrum during the first several hours after lambing. Ram lambs that will either be slaughtered or separated from ewes before sexual maturity are not usually castrated. Objections to all these procedures have been raised by animal rights groups, but farmers defend them by saying they save money, and inflict only temporary pain.
Homosexuality
Sheep are the only species of mammal except for humans which exhibits exclusive homosexual behavior. About 10% of rams refuse to mate with ewes but readily mate with other rams, and thirty percent of all rams demonstrate at least some homosexual behavior. Additionally, a small number of females that were accompanied by a male fetus in utero (i.e. as fraternal twins) are freemartins (female animals that are behaviorally masculine and lack functioning ovaries).
Health
Sheep may fall victim to poisons, infectious diseases, and physical injuries. As a prey species, a sheep's system is adapted to hide the obvious signs of illness, to prevent being targeted by predators. However, some signs of ill health are obvious, with sick sheep eating little, vocalizing excessively, and being generally listless. Throughout history, much of the money and labor of sheep husbandry has aimed to prevent sheep ailments. Historically, shepherds often created remedies by experimentation on the farm. In some developed countries, including the United States, sheep lack the economic importance for drug companies to perform expensive clinical trials required to approve more than a relatively limited number of drugs for ovine use. However, extra-label drug use in sheep production is permitted in many jurisdictions, subject to certain restrictions. In the US, for example, regulations governing extra-label drug use in animals are found in 21 CFR (Code of Federal Regulations) Part 530. In the 20th and 21st centuries, a minority of sheep owners have turned to alternative treatments such as homeopathy, herbalism and even traditional Chinese medicine to treat sheep veterinary problems. Despite some favorable anecdotal evidence, the effectiveness of alternative veterinary medicine has been met with skepticism in scientific journals. The need for traditional anti-parasite drugs and antibiotics is widespread, and is the main impediment to certified organic farming with sheep.
Many breeders take a variety of preventive measures to ward off problems. The first is to ensure all sheep are healthy when purchased. Many buyers avoid outlets known to be clearing houses for animals culled from healthy flocks as either sick or simply inferior. This can also mean maintaining a closed flock, and quarantining new sheep for a month. Two fundamental preventive programs are maintaining good nutrition and reducing stress in the sheep. Restraint, isolation, loud noises, novel situations, pain, heat, extreme cold, fatigue and other stressors can lead to secretion of cortisol, a stress hormone, in amounts that may indicate welfare problems. Excessive stress can compromise the immune system. "Shipping fever" (pneumonic mannheimiosis, formerly called pasteurellosis) is a disease of particular concern, that can occur as a result of stress, notably during transport and (or) handling. Pain, fear and several other stressors can cause secretion of epinephrine (adrenaline). Considerable epinephrine secretion in the final days before slaughter can adversely affect meat quality (by causing glycogenolysis, removing the substrate for normal post-slaughter acidification of meat) and result in meat becoming more susceptible to colonization by spoilage bacteria. Because of such issues, low-stress handling is essential in sheep management. Avoiding poisoning is also important; common poisons are pesticide sprays, inorganic fertilizer, motor oil, as well as radiator coolant containing ethylene glycol.
Common forms of preventive medication for sheep are vaccinations and treatments for parasites. Both external and internal parasites are the most prevalent malady in sheep, and are either fatal, or reduce the productivity of flocks. Worms are the most common internal parasites. They are ingested during grazing, incubate within the sheep, and are expelled through the digestive system (beginning the cycle again). Oral anti-parasitic medicines, known as drenches, are given to a flock to treat worms, sometimes after worm eggs in the feces has been counted to assess infestation levels. Afterwards, sheep may be moved to a new pasture to avoid ingesting the same parasites. External sheep parasites include: lice (for different parts of the body), sheep keds, nose bots, sheep itch mites, and maggots. Keds are blood-sucking parasites that cause general malnutrition and decreased productivity, but are not fatal. Maggots are those of the bot fly and the blow-fly, commonly Lucilia sericata or its relative L. cuprina. Fly maggots cause the extremely destructive condition of flystrike. Flies lay their eggs in wounds or wet, manure-soiled wool; when the maggots hatch they burrow into a sheep's flesh, eventually causing death if untreated. In addition to other treatments, crutching (shearing wool from a sheep's rump) is a common preventive method. Some countries allow mulesing, a practice that involves stripping away the skin on the rump to prevent fly-strike, normally performed when the sheep is a lamb. Nose bots are fly larvae that inhabit a sheep's sinuses, causing breathing difficulties and discomfort. Common signs are a discharge from the nasal passage, sneezing, and frantic movement such as head shaking. External parasites may be controlled through the use of backliners, sprays or immersive sheep dips.
A wide array of bacterial and viral diseases affect sheep. Diseases of the hoof, such as foot rot and foot scald may occur, and are treated with footbaths and other remedies. Foot rot is present in over 97% of flocks in the UK. These painful conditions cause lameness and hinder feeding. Ovine Johne's disease is a wasting disease that affects young sheep. Bluetongue disease is an insect-borne illness causing fever and inflammation of the mucous membranes. Ovine rinderpest (or peste des petits ruminants) is a highly contagious and often fatal viral disease affecting sheep and goats. Sheep may also be affected by primary or secondary photosensitization. Tetanus can also afflict sheep through wounds from shearing, docking, castration, or vaccination. The organism also can be introduced into the reproductive tract by unsanitary humans who assist ewes during lambing.
A few sheep conditions are transmissible to humans. Orf (also known as scabby mouth, contagious ecthyma or soremouth) is a skin disease leaving lesions that is transmitted through skin-to-skin contact. Cutaneous anthrax is also called woolsorter's disease, as the spores can be transmitted in unwashed wool. More seriously, the organisms that can cause spontaneous enzootic abortion in sheep are easily transmitted to pregnant women. Also of concern are the prion disease scrapie and the virus that causes foot-and-mouth disease (FMD), as both can devastate flocks. The latter poses a slight risk to humans. During the 2001 FMD pandemic in the UK, hundreds of sheep were culled and some rare British breeds were at risk of extinction due to this.
Of the 600,300 sheep lost to the US economy in 2004, 37.3% were lost to predators, while 26.5% were lost to some form of disease. Poisoning accounted for 1.7% of non-productive deaths.
Predators

Other than parasites and disease, predation is a threat to sheep and the profitability of sheep raising. Sheep have little ability to defend themselves, compared with other species kept as livestock. Even if sheep survive an attack, they may die from their injuries or simply from panic. However, the impact of predation varies dramatically with region. In Africa, Australia, the Americas, and parts of Europe and Asia predators are a serious problem. In the United States, for instance, over one third of sheep deaths in 2004 were caused by predation. In contrast, other nations are virtually devoid of sheep predators, particularly islands known for extensive sheep husbandry. Worldwide, canids—including the domestic dog—are responsible for most sheep deaths. Other animals that occasionally prey on sheep include: felines, bears, birds of prey, ravens and feral hogs.
Sheep producers have used a wide variety of measures to combat predation. Pre-modern shepherds used their own presence, livestock guardian dogs, and protective structures such as barns and fencing. Fencing (both regular and electric), penning sheep at night and lambing indoors all continue to be widely used. More modern shepherds used guns, traps, and poisons to kill predators, causing significant decreases in predator populations. In the wake of the environmental and conservation movements, the use of these methods now usually falls under the purview of specially designated government agencies in most developed countries.
The 1970s saw a resurgence in the use of livestock guardian dogs and the development of new methods of predator control by sheep producers, many of them non-lethal. Donkeys and guard llamas have been used since the 1980s in sheep operations, using the same basic principle as livestock guardian dogs. Interspecific pasturing, usually with larger livestock such as cattle or horses, may help to deter predators, even if such species do not actively guard sheep. In addition to animal guardians, contemporary sheep operations may use non-lethal predator deterrents such as motion-activated lights and noisy alarms.

Sheep are an important part of the global agricultural economy. However, their once vital status has been largely replaced by other livestock species, especially the pig, chicken, and cow. China, Australia, India, and Iran have the largest modern flocks, and serve both local and exportation needs for wool and mutton. Other countries such as New Zealand have smaller flocks but retain a large international economic impact due to their export of sheep products. Sheep also play a major role in many local economies, which may be niche markets focused on organic or sustainable agriculture and local food customers. Especially in developing countries, such flocks may be a part of subsistence agriculture rather than a system of trade. Sheep themselves may be a medium of trade in barter economies.
Domestic sheep provide a wide array of raw materials. Wool was one of the first textiles, although in the late 20th century wool prices began to fall dramatically as the result of the popularity and cheap prices for synthetic fabrics. For many sheep owners, the cost of shearing is greater than the possible profit from the fleece, making subsisting on wool production alone practically impossible without farm subsidies. Fleeces are used as material in making alternative products such as wool insulation. In the 21st century, the sale of meat is the most profitable enterprise in the sheep industry, even though far less sheep meat is consumed than chicken, pork or beef.
Sheepskin is likewise used for making clothes, footwear, rugs, and other products. Byproducts from the slaughter of sheep are also of value: sheep tallow can be used in candle and soap making, sheep bone and cartilage has been used to furnish carved items such as dice and buttons as well as rendered glue and gelatin. Sheep intestine can be formed into sausage casings, and lamb intestine has been formed into surgical sutures, as well as strings for musical instruments and tennis rackets. Sheep droppings, which are high in cellulose, have even been sterilized and mixed with traditional pulp materials to make paper. Of all sheep byproducts, perhaps the most valuable is lanolin: the waterproof, fatty substance found naturally in sheep's wool and used as a base for innumerable cosmetics and other products.
Some farmers who keep sheep also make a profit from live sheep. Providing lambs for youth programs such as 4-H and competition at agricultural shows is often a dependable avenue for the sale of sheep. Farmers may also choose to focus on a particular breed of sheep in order to sell registered purebred animals, as well as provide a ram rental service for breeding. A new option for deriving profit from live sheep is the rental of flocks for grazing; these "mowing services" are hired in order to keep unwanted vegetation down in public spaces and to lessen fire hazard.
Despite the falling demand and price for sheep products in many markets, sheep have distinct economic advantages when compared with other livestock. They do not require expensive housing, such as that used in the intensive farming of chickens or pigs. They are an efficient use of land; roughly six sheep can be kept on the amount that would suffice for a single cow or horse. Sheep can also consume plants, such as noxious weeds, that most other animals will not touch, and produce more young at a faster rate. Also, in contrast to most livestock species, the cost of raising sheep is not necessarily tied to the price of feed crops such as grain, soybeans and corn. Combined with the lower cost of quality sheep, all these factors combine to equal a lower overhead for sheep producers, thus entailing a higher profitability potential for the small farmer. Sheep are especially beneficial for independent producers, including family farms with limited resources, as the sheep industry is one of the few types of animal agriculture that has not been vertically integrated by agribusiness. However, small flocks, from 10 to 50 ewes, often are not profitable because they tend to be poorly managed. The primary reason is that mechanization is not feasible, so return per hour of labor is not maximized. Small farm flocks generally are used simply to control weeds on irrigation ditches or maintained as a hobby.
Shoulder of lamb
Sheep meat and milk were one of the earliest staple proteins consumed by human civilization after the transition from hunting and gathering to agriculture. Sheep meat prepared for food is known as either mutton or lamb, and approximately 540 million sheep are slaughtered each year for meat worldwide. "Mutton" is derived from the Old French moton, which was the word for sheep used by the Anglo-Norman rulers of much of the British Isles in the Middle Ages. This became the name for sheep meat in English, while the Old English word sceap was kept for the live animal. Throughout modern history, "mutton" has been limited to the meat of mature sheep usually at least two years of age; "lamb" is used for that of immature sheep less than a year.
In the 21st century, the nations with the highest consumption of sheep meat are the Arab states of the Persian Gulf, New Zealand, Australia, Greece, Uruguay, the United Kingdom and Ireland. These countries eat 14–40 lbs (3–18 kg) of sheep meat per capita, per annum. Sheep meat is also popular in France, Africa (especially the Arab world), the Caribbean, the rest of the Middle East, India, and parts of China. This often reflects a history of sheep production. In these countries in particular, dishes comprising alternative cuts and offal may be popular or traditional. Sheep testicles—called animelles or lamb fries—are considered a delicacy in many parts of the world. Perhaps the most unusual dish of sheep meat is the Scottish haggis, composed of various sheep innards cooked along with oatmeal and chopped onions inside its stomach. In comparison, countries such as the U.S. consume only a pound or less (under 0.5 kg), with Americans eating 50 pounds (22 kg) of pork and 65 pounds (29 kg) of beef. In addition, such countries rarely eat mutton, and may favor the more expensive cuts of lamb: mostly lamb chops and leg of lamb.
Though sheep's milk may be drunk rarely in fresh form, today it is used predominantly in cheese and yogurt making. Sheep have only two teats, and produce a far smaller volume of milk than cows. However, as sheep's milk contains far more fat, solids, and minerals than cow's milk, it is ideal for the cheese-making process. It also resists contamination during cooling better because of its much higher calcium content. Well-known cheeses made from sheep milk include the feta of Bulgaria and Greece, Roquefort of France, Manchego from Spain, the pecorino romano (the Italian word for "sheep" is pecore) and ricotta of Italy. Yogurts, especially some forms of strained yogurt, may also be made from sheep milk. Many of these products are now often made with cow's milk, especially when produced outside their country of origin. Sheep milk contains 4.8% lactose, which may affect those who are intolerant.
As with other domestic animals, the meat of uncastrated males is inferior in quality, especially as they grow. A "bucky" lamb is a lamb which was not castrated early enough, or which was castrated improperly (resulting in one testicle being retained). These lambs are worth less at market.
In science
Sheep are generally too large and reproduce too slowly to make ideal research subjects, and thus are not a common model organism. They have, however, played an influential role in some fields of science. In particular, the Roslin Institute of Edinburgh, Scotland used sheep for genetics research that produced groundbreaking results. In 1995, two ewes named Megan and Morag were the first mammals cloned from differentiated cells, also referred to as gynomerogony. A year later, a Finnish Dorset sheep named Dolly, dubbed "the world's most famous sheep" in Scientific American, was the first mammal to be cloned from an adult somatic cell. Following this, Polly and Molly were the first mammals to be simultaneously cloned and transgenic.
As of 2008, the sheep genome has not been fully sequenced, although a detailed genetic map has been published, and a draft version of the complete genome produced by assembling sheep DNA sequences using information given by the genomes of other mammals. In 2012, a transgenic sheep named "Peng Peng" was cloned by Chinese scientists, who spliced his genes with that of a roundworm (C. elegans) in order to increase production of fats healthier for human consumption.
In the study of natural selection, the population of Soay sheep that remain on the island of Hirta have been used to explore the relation of body size and coloration to reproductive success. Soay sheep come in several colors, and researchers investigated why the larger, darker sheep were in decline; this occurrence contradicted the rule of thumb that larger members of a population tend to be more successful reproductively. The feral Soays on Hirta are especially useful subjects because they are isolated.
Domestic sheep are sometimes used in medical research, particularly for researching cardiovascular physiology, in areas such as hypertension and heart failure. Pregnant sheep are also a useful model for human pregnancy, and have been used to investigate the effects on fetal development of malnutrition and hypoxia. In behavioral sciences, sheep have been used in isolated cases for the study of facial recognition, as their mental process of recognition is qualitatively similar to humans.
Cultural impact
Sheep have had a strong presence in many cultures, especially in areas where they form the most common type of livestock. In the English language, to call someone a sheep or ovine may allude that they are timid and easily led. In contradiction to this image, male sheep are often used as symbols of virility and power; the logos of the Los Angeles Rams football team and the Dodge Ram pickup truck allude to males of the bighorn sheep, Ovis canadensis.
Counting sheep is popularly said to be an aid to sleep, and some ancient systems of counting sheep persist today. Sheep also enter in colloquial sayings and idiom frequently with such phrases as "black sheep". To call an individual a black sheep implies that they are an odd or disreputable member of a group. This usage derives from the recessive trait that causes an occasional black lamb to be born into an entirely white flock. These black sheep were considered undesirable by shepherds, as black wool is not as commercially viable as white wool. Citizens who accept overbearing governments have been referred to by the Portmanteau neologism of sheeple. Somewhat differently, the adjective "sheepish" is also used to describe embarrassment.
In heraldry
In British heraldry, sheep appear in the form of rams, sheep proper and lambs. These are distinguished by the ram being depicted with horns and a tail, the sheep with neither and the lamb with its tail only. A further variant of the lamb, termed the Paschal lamb, is depicted as carrying a Christian cross and with a halo over its head. Rams' heads, portrayed without a neck and facing the viewer, are also found in British armories. The fleece, depicted as an entire sheepskin carried by a ring around its midsection, originally became known through its use in the arms of the Order of the Golden Fleece and was later adopted by towns and individuals with connections to the wool industry. A sheep on a blue field is depicted on the greater/royal arms of the king of Denmark to represent the Faroe Islands. In 2004 a modernized arms has been adopted by the Faroe Islands, which based on a 15th century coat of arms.
Religion and folklore
In antiquity, symbolism involving sheep cropped up in religions in the ancient Near East, the Mideast, and the Mediterranean area: Çatalhöyük, ancient Egyptian religion, the Cana'anite and Phoenician tradition, Judaism, Greek religion, and others. Religious symbolism and ritual involving sheep began with some of the first known faiths: Skulls of rams (along with bulls) occupied central placement in shrines at the Çatalhöyük settlement in 8,000 BCE. In Ancient Egyptian religion, the ram was the symbol of several gods: Khnum, Heryshaf and Amun (in his incarnation as a god of fertility). Other deities occasionally shown with ram features include the goddess Ishtar, the Phoenician god Baal-Hamon, and the Babylonian god Ea-Oannes. In Madagascar, sheep were not eaten as they were believed to be incarnations of the souls of ancestors.
There are many ancient Greek references to sheep: that of Chrysomallos, the golden-fleeced ram, continuing to be told through into the modern era. Astrologically, Aries, the ram, is the first sign of the classical Greek zodiac, and the sheep is the eighth of the twelve animals associated with the 12-year cycle of in the Chinese zodiac, related to the Chinese calendar. It is said in Chinese traditions that Hou ji sacrificed sheep. Mongolia, shagai are an ancient form of dice made from the cuboid bones of sheep that are often used for fortunetelling purposes.
Sheep play an important role in all the Abrahamic faiths; Abraham, Isaac, Jacob, Moses, and King David were all shepherds. According to the Biblical story of the Binding of Isaac, a ram is sacrificed as a substitute for Isaac after an angel stays Abraham's hand (in the Islamic tradition, Abraham was about to sacrifice Ishmael). Eid al-Adha is a major annual festival in Islam in which sheep (or other animals) are sacrificed in remembrance of this act. Sheep are occasionally sacrificed to commemorate important secular events in Islamic cultures. Greeks and Romans sacrificed sheep regularly in religious practice, and Judaism once sacrificed sheep as a Korban (sacrifice), such as the Passover lamb. Ovine symbols—such as the ceremonial blowing of a shofar—still find a presence in modern Judaic traditions.
Collectively, followers of Christianity are often referred to as a flock, with Christ as the Good Shepherd, and sheep are an element in the Christian iconography of the birth of Jesus. Some Christian saints are considered patrons of shepherds, and even of sheep themselves. Christ is also portrayed as the Sacrificial lamb of God (Agnus Dei) and Easter celebrations in Greece and Romania traditionally feature a meal of Paschal lamb. A church leader is often called the pastor, which is derived from the Latin word for shepherd. In many western Christian traditions bishops carry a staff, which also serves as a symbol of the episcopal office, known as a crosier, which is modeled on the shepherd's crook.
Sheep are key symbols in fables and nursery rhymes like The Wolf in Sheep's Clothing, Little Bo Peep, Baa, Baa, Black Sheep, and Mary Had a Little Lamb; novels such as George Orwell's Animal Farm and Haruki Murakami's A Wild Sheep Chase; songs such as Bach's Sheep may safely graze (Schafe können sicher weiden) and Pink Floyd's "Sheep", and poems like William Blake's "The Lamb".

Sheep (pl.: sheep) or domestic sheep (Ovis aries) are a domesticated, ruminant mammal typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (/juː/ yoo), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonwealth countries, ovine meat is called lamb when from younger animals and mutton when from older ones; in the United States, meat from both older and younger animals is usually called lamb. Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science.
Sheep husbandry is practised throughout the majority of the inhabited world, and has been fundamental to many civilizations. In the modern era, Australia, New Zealand, the southern and central South American nations, and the British Isles are most closely associated with sheep production.
There is a large lexicon of unique terms for sheep husbandry which vary considerably by region and dialect. Use of the word sheep began in Middle English as a derivation of the Old English word scēap. A group of sheep is called a flock. Many other specific terms for the various life stages of sheep exist, generally related to lambing, shearing, and age.
Being a key animal in the history of farming, sheep have a deeply entrenched place in human culture, and are represented in much modern language and symbolism. As livestock, sheep are most often associated with pastoral, Arcadian imagery. Sheep figure in many mythologies—such as the Golden Fleece—and major religions, especially the Abrahamic traditions. In both ancient and modern religious ritual, sheep are used as sacrificial animals.
History
Main article: History of the domestic sheep
The exact line of descent from wild ancestors to domestic sheep is unclear. The most common hypothesis states that Ovis aries is descended from the Asiatic (O. gmelini) species of mouflon; the European mouflon (Ovis aries musimon) is a direct descendant of this population. Sheep were among the first animals to be domesticated by humankind (although the domestication of dogs probably took place 10 to 20 thousand years earlier); the domestication date is estimated to fall between 11,000 and 9000 B.C in Mesopotamia and possibly around 7000 BC in Mehrgarh in the Indus Valley. The rearing of sheep for secondary products, and the resulting breed development, began in either southwest Asia or western Europe. Initially, sheep were kept solely for meat, milk and skins. Archaeological evidence from statuary found at sites in Iran suggests that selection for woolly sheep may have begun around 6000 BC, and the earliest woven wool garments have been dated to two to three thousand years later.
Sheep husbandry spread quickly in Europe. Excavations show that in about 6000 BC, during the Neolithic period of prehistory, the Castelnovien people, living around Châteauneuf-les-Martigues near present-day Marseille in the south of France, were among the first in Europe to keep domestic sheep. Practically from its inception, ancient Greek civilization relied on sheep as primary livestock, and were even said to name individual animals. Ancient Romans kept sheep on a wide scale, and were an important agent in the spread of sheep raising. Pliny the Elder, in his Natural History (Naturalis Historia), speaks at length about sheep and wool. European colonists spread the practice to the New World from 1493 onwards.
Characteristics
Domestic sheep are relatively small ruminants, usually with a crimped hair called wool and often with horns forming a lateral spiral. They differ from their wild relatives and ancestors in several respects, having become uniquely neotenic as a result of selective breeding by humans. A few primitive breeds of sheep retain some of the characteristics of their wild cousins, such as short tails. Depending on breed, domestic sheep may have no horns at all (i.e. polled), or horns in both sexes, or in males only. Most horned breeds have a single pair, but a few breeds may have several.

Another trait unique to domestic sheep as compared to wild ovines is their wide variation in color. Wild sheep are largely variations of brown hues, and variation within species is extremely limited. Colors of domestic sheep range from pure white to dark chocolate brown, and even spotted or piebald. Sheep keepers also sometimes artificially paint "smit marks" onto their sheep in any pattern or color for identification. Selection for easily dyeable white fleeces began early in sheep domestication, and as white wool is a dominant trait it spread quickly. However, colored sheep do appear in many modern breeds, and may even appear as a recessive trait in white flocks. While white wool is desirable for large commercial markets, there is a niche market for colored fleeces, mostly for handspinning. The nature of the fleece varies widely among the breeds, from dense and highly crimped, to long and hairlike. There is variation of wool type and quality even among members of the same flock, so wool classing is a step in the commercial processing of the fibre.
Suffolks are a medium wool, black-faced breed of meat sheep that make up 60% of the sheep population in the U.S.
Depending on breed, sheep show a range of heights and weights. Their rate of growth and mature weight is a heritable trait that is often selected for in breeding. Ewes typically weigh between 45 and 100 kilograms (100 and 220 lb), and rams between 45 and 160 kilograms (100 and 350 lb). When all deciduous teeth have erupted, the sheep has 20 teeth. Mature sheep have 32 teeth. As with other ruminants, the front teeth in the lower jaw bite against a hard, toothless pad in the upper jaw. These are used to pick off vegetation, then the rear teeth grind it before it is swallowed. There are eight lower front teeth in ruminants, but there is some disagreement as to whether these are eight incisors, or six incisors and two incisor-shaped canines. This means that the dental formula for sheep is either
0.0.3.3
4.0.3.3
or
0.0.3.3
3.1.3.3
There is a large diastema between the incisors and the molars.
In the first few years of life one can calculate the age of sheep from their front teeth, as a pair of milk teeth is replaced by larger adult teeth each year, the full set of eight adult front teeth being complete at about four years of age. The front teeth are then gradually lost as sheep age, making it harder for them to feed and hindering the health and productivity of the animal. For this reason, domestic sheep on normal pasture begin to slowly decline from four years on, and the life expectancy of a sheep is 10 to 12 years, though some sheep may live as long as 20 years.
Skull
Sheep have good hearing, and are sensitive to noise when being handled. Sheep have horizontal slit-shaped pupils, with excellent peripheral vision; with visual fields of about 270° to 320°, sheep can see behind themselves without turning their heads. Many breeds have only short hair on the face, and some have facial wool (if any) confined to the poll and or the area of the mandibular angle; the wide angles of peripheral vision apply to these breeds. A few breeds tend to have considerable wool on the face; for some individuals of these breeds, peripheral vision may be greatly reduced by "wool blindness", unless recently shorn about the face. Sheep have poor depth perception; shadows and dips in the ground may cause sheep to baulk. In general, sheep have a tendency to move out of the dark and into well-lit areas, and prefer to move uphill when disturbed. Sheep also have an excellent sense of smell, and, like all species of their genus, have scent glands just in front of the eyes, and interdigitally on the feet. The purpose of these glands is uncertain, but those on the face may be used in breeding behaviors. The foot glands might also be related to reproduction, but alternative functions, such as secretion of a waste product or a scent marker to help lost sheep find their flock, have also been proposed.
Comparison with goats
Sheep and goats are closely related: both are in the subfamily Caprinae. However, they are separate species, so hybrids rarely occur and are always infertile. A hybrid of a ewe and a buck (a male goat) is called a sheep-goat hybrid, known as geep. Visual differences between sheep and goats include the beard of goats and divided upper lip of sheep. Sheep tails also hang down, even when short or docked, while the short tails of goats are held upwards. Also, sheep breeds are often naturally polled (either in both sexes or just in the female), while naturally polled goats are rare (though many are polled artificially). Males of the two species differ in that buck goats acquire a unique and strong odor during the rut, whereas rams do not.
Breeds
The domestic sheep is a multi-purpose animal, and the more than 200 breeds now in existence were created to serve these diverse purposes. Some sources give a count of a thousand or more breeds, but these numbers cannot be verified, according to some sources. However, several hundred breeds of sheep have been identified by the Food and Agriculture Organization of the UN (FAO), with the estimated number varying somewhat from time to time: e.g. 863 breeds as of 1993, 1314 breeds as of 1995 and 1229 breeds as of 2006. (These numbers exclude extinct breeds, which are also tallied by the FAO.) For the purpose of such tallies, the FAO definition of a breed is "either a subspecific group of domestic livestock with definable and identifiable external characteristics that enable it to be separated by visual appraisal from other similarly defined groups within the same species or a group for which geographical and/or cultural separation from phenotypically similar groups has led to acceptance of its separate identity." Almost all sheep are classified as being best suited to furnishing a certain product: wool, meat, milk, hides, or a combination in a dual-purpose breed. Other features used when classifying sheep include face color (generally white or black), tail length, presence or lack of horns, and the topography for which the breed has been developed. This last point is especially stressed in the UK, where breeds are described as either upland (hill or mountain) or lowland breeds. A sheep may also be of a fat-tailed type, which is a dual-purpose sheep common in Africa and Asia with larger deposits of fat within and around its tail.
Breeds are often categorized by the type of their wool. Fine wool breeds are those that have wool of great crimp and density, which are preferred for textiles. Most of these were derived from Merino sheep, and the breed continues to dominate the world sheep industry. Downs breeds have wool between the extremes, and are typically fast-growing meat and ram breeds with dark faces. Some major medium wool breeds, such as the Corriedale, are dual-purpose crosses of long and fine-wooled breeds and were created for high-production commercial flocks. Long wool breeds are the largest of sheep, with long wool and a slow rate of growth. Long wool sheep are most valued for crossbreeding to improve the attributes of other sheep types. For example: the American Columbia breed was developed by crossing Lincoln rams (a long wool breed) with fine-wooled Rambouillet ewes.
Coarse or carpet wool sheep are those with a medium to long length wool of characteristic coarseness. Breeds traditionally used for carpet wool show great variability, but the chief requirement is a wool that will not break down under heavy use (as would that of the finer breeds). As the demand for carpet-quality wool declines, some breeders of this type of sheep are attempting to use a few of these traditional breeds for alternative purposes. Others have always been primarily meat-class sheep.
A minor class of sheep are the dairy breeds. Dual-purpose breeds that may primarily be meat or wool sheep are often used secondarily as milking animals, but there are a few breeds that are predominantly used for milking. These sheep produce a higher quantity of milk and have slightly longer lactation curves. In the quality of their milk, the fat and protein content percentages of dairy sheep vary from non-dairy breeds, but lactose content does not.
A last group of sheep breeds is that of fur or hair sheep, which do not grow wool at all. Hair sheep are similar to the early domesticated sheep kept before woolly breeds were developed, and are raised for meat and pelts. Some modern breeds of hair sheep, such as the Dorper, result from crosses between wool and hair breeds. For meat and hide producers, hair sheep are cheaper to keep, as they do not need shearing. Hair sheep are also more resistant to parasites and hot weather.
With the modern rise of corporate agribusiness and the decline of localized family farms, many breeds of sheep are in danger of extinction. The Rare Breeds Survival Trust of the UK lists 22 native breeds as having only 3,000 registered animals (each), and The Livestock Conservancy lists 14 as either "critical" or "threatened". Preferences for breeds with uniform characteristics and fast growth have pushed heritage (or heirloom) breeds to the margins of the sheep industry. Those that remain are maintained through the efforts of conservation organizations, breed registries, and individual farmers dedicated to their preservation.
Diet
Sheep are herbivorous mammals. Most breeds prefer to graze on grass and other short roughage, avoiding the taller woody parts of plants that goats readily consume. Both sheep and goats use their lips and tongues to select parts of the plant that are easier to digest or higher in nutrition. Sheep, however, graze well in monoculture pastures where most goats fare poorly.
Ruminant system of a sheep
Like all ruminants, sheep have a complex digestive system composed of four chambers, allowing them to break down cellulose from stems, leaves, and seed hulls into simpler carbohydrates. When sheep graze, vegetation is chewed into a mass called a bolus, which is then passed into the rumen, via the reticulum. The rumen is a 19- to 38-liter (5 to 10 gallon) organ in which feed is fermented. The fermenting organisms include bacteria, fungi, and protozoa. (Other important rumen organisms include some archaea, which produce methane from carbon dioxide.) The bolus is periodically regurgitated back to the mouth as cud for additional chewing and salivation. After fermentation in the rumen, feed passes into the reticulum and the omasum; special feeds such as grains may bypass the rumen altogether. After the first three chambers, food moves into the abomasum for final digestion before processing by the intestines. The abomasum is the only one of the four chambers analogous to the human stomach, and is sometimes called the "true stomach".
Other than forage, the other staple feed for sheep is hay, often during the winter months. The ability to thrive solely on pasture (even without hay) varies with breed, but all sheep can survive on this diet. Also included in some sheep's diets are minerals, either in a trace mix or in licks. Feed provided to sheep must be specially formulated, as most cattle, poultry, pig, and even some goat feeds contain levels of copper that are lethal to sheep. The same danger applies to mineral supplements such as salt licks.
Grazing behavior
Sheep follow a diurnal pattern of activity, feeding from dawn to dusk, stopping sporadically to rest and chew their cud. Ideal pasture for sheep is not lawnlike grass, but an array of grasses, legumes and forbs. Types of land where sheep are raised vary widely, from pastures that are seeded and improved intentionally to rough, native lands. Common plants toxic to sheep are present in most of the world, and include (but are not limited to) cherry, some oaks and acorns, tomato, yew, rhubarb, potato, and rhododendron.
Effects on pasture
Sheep are largely grazing herbivores, unlike browsing animals such as goats and deer that prefer taller foliage. With a much narrower face, sheep crop plants very close to the ground and can overgraze a pasture much faster than cattle. For this reason, many shepherds use managed intensive rotational grazing, where a flock is rotated through multiple pastures, giving plants time to recover. Paradoxically, sheep can both cause and solve the spread of invasive plant species. By disturbing the natural state of pasture, sheep and other livestock can pave the way for invasive plants. However, sheep also prefer to eat invasives such as cheatgrass, leafy spurge, kudzu and spotted knapweed over native species such as sagebrush, making grazing sheep effective for conservation grazing. Research conducted in Imperial County, California compared lamb grazing with herbicides for weed control in seedling alfalfa fields. Three trials demonstrated that grazing lambs were just as effective as herbicides in controlling winter weeds. Entomologists also compared grazing lambs to insecticides for insect control in winter alfalfa. In this trial, lambs provided insect control as effectively as insecticides.
Behavior
Sheep are flock animals and strongly gregarious; much sheep behavior can be understood on the basis of these tendencies. The dominance hierarchy of sheep and their natural inclination to follow a leader to new pastures were the pivotal factors in sheep being one of the first domesticated livestock species. Furthermore, in contrast to the red deer and gazelle (two other ungulates of primary importance to meat production in prehistoric times), sheep do not defend territories although they do form home ranges. All sheep have a tendency to congregate close to other members of a flock, although this behavior varies with breed, and sheep can become stressed when separated from their flock members. During flocking, sheep have a strong tendency to follow, and a leader may simply be the first individual to move. Relationships in flocks tend to be closest among related sheep: in mixed-breed flocks, subgroups of the same breed tend to form, and a ewe and her direct descendants often move as a unit within large flocks. Sheep can become hefted to one particular local pasture (heft) so they do not roam freely in unfenced landscapes. Lambs learn the heft from ewes and if whole flocks are culled it must be retaught to the replacement animals.
Flock behaviour in sheep is generally only exhibited in groups of four or more sheep; fewer sheep may not react as expected when alone or with few other sheep. Being a prey species, the primary defense mechanism of sheep is to flee from danger when their flight zone is entered. Cornered sheep may charge and butt, or threaten by hoof stamping and adopting an aggressive posture. This is particularly true for ewes with newborn lambs.
In regions where sheep have no natural predators, none of the native breeds of sheep exhibit a strong flocking behavior.
Herding
Farmers exploit flocking behavior to keep sheep together on unfenced pastures such as hill farming, and to move them more easily. For this purpose shepherds may use herding dogs in this effort, with a highly bred herding ability. Sheep are food-oriented, and association of humans with regular feeding often results in sheep soliciting people for food. Those who are moving sheep may exploit this behavior by leading sheep with buckets of feed.
Dominance hierarchy
Sheep establish a dominance hierarchy through fighting, threats and competitiveness. Dominant animals are inclined to be more aggressive with other sheep, and usually feed first at troughs. Primarily among rams, horn size is a factor in the flock hierarchy. Rams with different size horns may be less inclined to fight to establish the dominance order, while rams with similarly sized horns are more so. Merinos have an almost linear hierarchy whereas there is a less rigid structure in Border Leicesters when a competitive feeding situation arises.
In sheep, position in a moving flock is highly correlated with social dominance, but there is no definitive study to show consistent voluntary leadership by an individual sheep.
Intelligence and learning ability
Sheep are frequently thought of as unintelligent animals. Their flocking behavior and quickness to flee and panic can make shepherding a difficult endeavor for the uninitiated. Despite these perceptions, a University of Illinois monograph on sheep reported their intelligence to be just below that of pigs and on par with that of cattle. Sheep can recognize individual human and ovine faces and remember them for years; they can remember 50 other different sheep faces for over two years; they can recognize and are attracted to individual sheep and humans by their faces, as they possess similar specialized neural systems in the temporal and frontal lobes of their brains to humans and have a greater involvement of the right brain hemisphere. In addition to long-term facial recognition of individuals, sheep can also differentiate emotional states through facial characteristics.[68][69] If worked with patiently, sheep may learn their names, and many sheep are trained to be led by halter for showing and other purposes. Sheep have also responded well to clicker training. Sheep have been used as pack animals; Tibetan nomads distribute baggage equally throughout a flock as it is herded between living sites.
It has been reported that some sheep have apparently shown problem-solving abilities; a flock in West Yorkshire, England allegedly found a way to get over cattle grids by rolling on their backs, although documentation of this has relied on anecdotal accounts.
Vocalisations
Sounds made by domestic sheep include bleats, grunts, rumbles and snorts. Bleating ("baaing") is used mostly for contact communication, especially between dam and lambs, but also at times between other flock members. The bleats of individual sheep are distinctive, enabling the ewe and her lambs to recognize each other's vocalizations. Vocal communication between lambs and their dam declines to a very low level within several weeks after parturition. A variety of bleats may be heard, depending on sheep age and circumstances. Apart from contact communication, bleating may signal distress, frustration or impatience; however, sheep are usually silent when in pain. Isolation commonly prompts bleating by sheep. Pregnant ewes may grunt when in labor. Rumbling sounds are made by the ram during courting; somewhat similar rumbling sounds may be made by the ewe, especially when with her neonate lambs. A snort (explosive exhalation through the nostrils) may signal aggression or a warning, and is often elicited from startled sheep.
Lamb
In sheep breeds lacking facial wool, the visual field is wide. In 10 sheep (Cambridge, Lleyn and Welsh Mountain breeds, which lack facial wool), the visual field ranged from 298° to 325°, averaging 313.1°, with binocular overlap ranging from 44.5° to 74°, averaging 61.7°. In some breeds, unshorn facial wool can limit the visual field; in some individuals, this may be enough to cause "wool blindness". In 60 Merinos, visual fields ranged from 219.1° to 303.0°, averaging 269.9°, and the binocular field ranged from 8.9° to 77.7°, averaging 47.5°; 36% of the measurements were limited by wool, although photographs of the experiments indicate that only limited facial wool regrowth had occurred since shearing. In addition to facial wool (in some breeds), visual field limitations can include ears and (in some breeds) horns, so the visual field can be extended by tilting the head. Sheep eyes exhibit very low hyperopia and little astigmatism. Such visual characteristics are likely to produce a well-focused retinal image of objects in both the middle and long distance. Because sheep eyes have no accommodation, one might expect the image of very near objects to be blurred, but a rather clear near image could be provided by the tapetum and large retinal image of the sheep's eye, and adequate close vision may occur at muzzle length. Good depth perception, inferred from the sheep's sure-footedness, was confirmed in "visual cliff" experiments; behavioral responses indicating depth perception are seen in lambs at one day old. Sheep are thought to have colour vision, and can distinguish between a variety of colours: black, red, brown, green, yellow and white. Sight is a vital part of sheep communication, and when grazing, they maintain visual contact with each other. Each sheep lifts its head upwards to check the position of other sheep in the flock. This constant monitoring is probably what keeps the sheep in a flock as they move along grazing. Sheep become stressed when isolated; this stress is reduced if they are provided with a mirror, indicating that the sight of other sheep reduces stress.
Taste is the most important sense in sheep, establishing forage preferences, with sweet and sour plants being preferred and bitter plants being more commonly rejected. Touch and sight are also important in relation to specific plant characteristics, such as succulence and growth form.
The ram uses his vomeronasal organ (sometimes called the Jacobson's organ) to sense the pheromones of ewes and detect when they are in estrus. The ewe uses her vomeronasal organ for early recognition of her neonate lamb.
Reproduction
Sheep follow a similar reproductive strategy to other herd animals. A group of ewes is generally mated by a single ram, who has either been chosen by a breeder or (in feral populations) has established dominance through physical contest with other rams. Most sheep are seasonal breeders, although some are able to breed year-round. Ewes generally reach sexual maturity at six to eight months old, and rams generally at four to six months. However, there are exceptions. For example, Finnsheep ewe lambs may reach puberty as early as 3 to 4 months, and Merino ewes sometimes reach puberty at 18 to 20 months. Ewes have estrus cycles about every 17 days, during which they emit a scent and indicate readiness through physical displays towards rams.
In feral sheep, rams may fight during the rut to determine which individuals may mate with ewes. Rams, especially unfamiliar ones, will also fight outside the breeding period to establish dominance; rams can kill one another if allowed to mix freely. During the rut, even usually friendly rams may become aggressive towards humans due to increases in their hormone levels.
After mating, sheep have a gestation period of about five months, and normal labor takes one to three hours. Although some breeds regularly throw larger litters of lambs, most produce single or twin lambs. During or soon after labor, ewes and lambs may be confined to small lambing jugs, small pens designed to aid both careful observation of ewes and to cement the bond between them and their lambs.
A lamb's first steps
Ovine obstetrics can be problematic. By selectively breeding ewes that produce multiple offspring with higher birth weights for generations, sheep producers have inadvertently caused some domestic sheep to have difficulty lambing; balancing ease of lambing with high productivity is one of the dilemmas of sheep breeding. In the case of any such problems, those present at lambing may assist the ewe by extracting or repositioning lambs. After the birth, ewes ideally break the amniotic sac (if it is not broken during labor), and begin licking clean the lamb. Most lambs will begin standing within an hour of birth. In normal situations, lambs nurse after standing, receiving vital colostrum milk. Lambs that either fail to nurse or are rejected by the ewe require help to survive, such as bottle-feeding or fostering by another ewe.
Most lambs begin life being born outdoors. After lambs are several weeks old, lamb marking (ear tagging, docking, mulesing, and castrating) is carried out. Vaccinations are usually carried out at this point as well. Ear tags with numbers are attached, or ear marks are applied, for ease of later identification of sheep. Docking and castration are commonly done after 24 hours (to avoid interference with maternal bonding and consumption of colostrum) and are often done not later than one week after birth, to minimize pain, stress, recovery time and complications. The first course of vaccinations (commonly anti-clostridial) is commonly given at an age of about 10 to 12 weeks; i.e. when the concentration of maternal antibodies passively acquired via colostrum is expected to have fallen low enough to permit development of active immunity. Ewes are often revaccinated annually about 3 weeks before lambing, to provide high antibody concentrations in colostrum during the first several hours after lambing. Ram lambs that will either be slaughtered or separated from ewes before sexual maturity are not usually castrated. Objections to all these procedures have been raised by animal rights groups, but farmers defend them by saying they save money, and inflict only temporary pain.
Homosexuality
Sheep are the only species of mammal except for humans which exhibits exclusive homosexual behavior. About 10% of rams refuse to mate with ewes but readily mate with other rams, and thirty percent of all rams demonstrate at least some homosexual behavior. Additionally, a small number of females that were accompanied by a male fetus in utero (i.e. as fraternal twins) are freemartins (female animals that are behaviorally masculine and lack functioning ovaries).
Health
Sheep may fall victim to poisons, infectious diseases, and physical injuries. As a prey species, a sheep's system is adapted to hide the obvious signs of illness, to prevent being targeted by predators. However, some signs of ill health are obvious, with sick sheep eating little, vocalizing excessively, and being generally listless. Throughout history, much of the money and labor of sheep husbandry has aimed to prevent sheep ailments. Historically, shepherds often created remedies by experimentation on the farm. In some developed countries, including the United States, sheep lack the economic importance for drug companies to perform expensive clinical trials required to approve more than a relatively limited number of drugs for ovine use. However, extra-label drug use in sheep production is permitted in many jurisdictions, subject to certain restrictions. In the US, for example, regulations governing extra-label drug use in animals are found in 21 CFR (Code of Federal Regulations) Part 530. In the 20th and 21st centuries, a minority of sheep owners have turned to alternative treatments such as homeopathy, herbalism and even traditional Chinese medicine to treat sheep veterinary problems. Despite some favorable anecdotal evidence, the effectiveness of alternative veterinary medicine has been met with skepticism in scientific journals. The need for traditional anti-parasite drugs and antibiotics is widespread, and is the main impediment to certified organic farming with sheep.
Many breeders take a variety of preventive measures to ward off problems. The first is to ensure all sheep are healthy when purchased. Many buyers avoid outlets known to be clearing houses for animals culled from healthy flocks as either sick or simply inferior. This can also mean maintaining a closed flock, and quarantining new sheep for a month. Two fundamental preventive programs are maintaining good nutrition and reducing stress in the sheep. Restraint, isolation, loud noises, novel situations, pain, heat, extreme cold, fatigue and other stressors can lead to secretion of cortisol, a stress hormone, in amounts that may indicate welfare problems. Excessive stress can compromise the immune system. "Shipping fever" (pneumonic mannheimiosis, formerly called pasteurellosis) is a disease of particular concern, that can occur as a result of stress, notably during transport and (or) handling. Pain, fear and several other stressors can cause secretion of epinephrine (adrenaline). Considerable epinephrine secretion in the final days before slaughter can adversely affect meat quality (by causing glycogenolysis, removing the substrate for normal post-slaughter acidification of meat) and result in meat becoming more susceptible to colonization by spoilage bacteria. Because of such issues, low-stress handling is essential in sheep management. Avoiding poisoning is also important; common poisons are pesticide sprays, inorganic fertilizer, motor oil, as well as radiator coolant containing ethylene glycol.
Common forms of preventive medication for sheep are vaccinations and treatments for parasites. Both external and internal parasites are the most prevalent malady in sheep, and are either fatal, or reduce the productivity of flocks. Worms are the most common internal parasites. They are ingested during grazing, incubate within the sheep, and are expelled through the digestive system (beginning the cycle again). Oral anti-parasitic medicines, known as drenches, are given to a flock to treat worms, sometimes after worm eggs in the feces has been counted to assess infestation levels. Afterwards, sheep may be moved to a new pasture to avoid ingesting the same parasites. External sheep parasites include: lice (for different parts of the body), sheep keds, nose bots, sheep itch mites, and maggots. Keds are blood-sucking parasites that cause general malnutrition and decreased productivity, but are not fatal. Maggots are those of the bot fly and the blow-fly, commonly Lucilia sericata or its relative L. cuprina. Fly maggots cause the extremely destructive condition of flystrike. Flies lay their eggs in wounds or wet, manure-soiled wool; when the maggots hatch they burrow into a sheep's flesh, eventually causing death if untreated. In addition to other treatments, crutching (shearing wool from a sheep's rump) is a common preventive method. Some countries allow mulesing, a practice that involves stripping away the skin on the rump to prevent fly-strike, normally performed when the sheep is a lamb. Nose bots are fly larvae that inhabit a sheep's sinuses, causing breathing difficulties and discomfort. Common signs are a discharge from the nasal passage, sneezing, and frantic movement such as head shaking. External parasites may be controlled through the use of backliners, sprays or immersive sheep dips.
A wide array of bacterial and viral diseases affect sheep. Diseases of the hoof, such as foot rot and foot scald may occur, and are treated with footbaths and other remedies. Foot rot is present in over 97% of flocks in the UK. These painful conditions cause lameness and hinder feeding. Ovine Johne's disease is a wasting disease that affects young sheep. Bluetongue disease is an insect-borne illness causing fever and inflammation of the mucous membranes. Ovine rinderpest (or peste des petits ruminants) is a highly contagious and often fatal viral disease affecting sheep and goats. Sheep may also be affected by primary or secondary photosensitization. Tetanus can also afflict sheep through wounds from shearing, docking, castration, or vaccination. The organism also can be introduced into the reproductive tract by unsanitary humans who assist ewes during lambing.
A few sheep conditions are transmissible to humans. Orf (also known as scabby mouth, contagious ecthyma or soremouth) is a skin disease leaving lesions that is transmitted through skin-to-skin contact. Cutaneous anthrax is also called woolsorter's disease, as the spores can be transmitted in unwashed wool. More seriously, the organisms that can cause spontaneous enzootic abortion in sheep are easily transmitted to pregnant women. Also of concern are the prion disease scrapie and the virus that causes foot-and-mouth disease (FMD), as both can devastate flocks. The latter poses a slight risk to humans. During the 2001 FMD pandemic in the UK, hundreds of sheep were culled and some rare British breeds were at risk of extinction due to this.
Of the 600,300 sheep lost to the US economy in 2004, 37.3% were lost to predators, while 26.5% were lost to some form of disease. Poisoning accounted for 1.7% of non-productive deaths.
Predators

Other than parasites and disease, predation is a threat to sheep and the profitability of sheep raising. Sheep have little ability to defend themselves, compared with other species kept as livestock. Even if sheep survive an attack, they may die from their injuries or simply from panic. However, the impact of predation varies dramatically with region. In Africa, Australia, the Americas, and parts of Europe and Asia predators are a serious problem. In the United States, for instance, over one third of sheep deaths in 2004 were caused by predation. In contrast, other nations are virtually devoid of sheep predators, particularly islands known for extensive sheep husbandry. Worldwide, canids—including the domestic dog—are responsible for most sheep deaths. Other animals that occasionally prey on sheep include: felines, bears, birds of prey, ravens and feral hogs.
Sheep producers have used a wide variety of measures to combat predation. Pre-modern shepherds used their own presence, livestock guardian dogs, and protective structures such as barns and fencing. Fencing (both regular and electric), penning sheep at night and lambing indoors all continue to be widely used. More modern shepherds used guns, traps, and poisons to kill predators, causing significant decreases in predator populations. In the wake of the environmental and conservation movements, the use of these methods now usually falls under the purview of specially designated government agencies in most developed countries.
The 1970s saw a resurgence in the use of livestock guardian dogs and the development of new methods of predator control by sheep producers, many of them non-lethal. Donkeys and guard llamas have been used since the 1980s in sheep operations, using the same basic principle as livestock guardian dogs. Interspecific pasturing, usually with larger livestock such as cattle or horses, may help to deter predators, even if such species do not actively guard sheep. In addition to animal guardians, contemporary sheep operations may use non-lethal predator deterrents such as motion-activated lights and noisy alarms.

Sheep are an important part of the global agricultural economy. However, their once vital status has been largely replaced by other livestock species, especially the pig, chicken, and cow. China, Australia, India, and Iran have the largest modern flocks, and serve both local and exportation needs for wool and mutton. Other countries such as New Zealand have smaller flocks but retain a large international economic impact due to their export of sheep products. Sheep also play a major role in many local economies, which may be niche markets focused on organic or sustainable agriculture and local food customers. Especially in developing countries, such flocks may be a part of subsistence agriculture rather than a system of trade. Sheep themselves may be a medium of trade in barter economies.
Domestic sheep provide a wide array of raw materials. Wool was one of the first textiles, although in the late 20th century wool prices began to fall dramatically as the result of the popularity and cheap prices for synthetic fabrics. For many sheep owners, the cost of shearing is greater than the possible profit from the fleece, making subsisting on wool production alone practically impossible without farm subsidies. Fleeces are used as material in making alternative products such as wool insulation. In the 21st century, the sale of meat is the most profitable enterprise in the sheep industry, even though far less sheep meat is consumed than chicken, pork or beef.
Sheepskin is likewise used for making clothes, footwear, rugs, and other products. Byproducts from the slaughter of sheep are also of value: sheep tallow can be used in candle and soap making, sheep bone and cartilage has been used to furnish carved items such as dice and buttons as well as rendered glue and gelatin. Sheep intestine can be formed into sausage casings, and lamb intestine has been formed into surgical sutures, as well as strings for musical instruments and tennis rackets. Sheep droppings, which are high in cellulose, have even been sterilized and mixed with traditional pulp materials to make paper. Of all sheep byproducts, perhaps the most valuable is lanolin: the waterproof, fatty substance found naturally in sheep's wool and used as a base for innumerable cosmetics and other products.
Some farmers who keep sheep also make a profit from live sheep. Providing lambs for youth programs such as 4-H and competition at agricultural shows is often a dependable avenue for the sale of sheep. Farmers may also choose to focus on a particular breed of sheep in order to sell registered purebred animals, as well as provide a ram rental service for breeding. A new option for deriving profit from live sheep is the rental of flocks for grazing; these "mowing services" are hired in order to keep unwanted vegetation down in public spaces and to lessen fire hazard.
Despite the falling demand and price for sheep products in many markets, sheep have distinct economic advantages when compared with other livestock. They do not require expensive housing, such as that used in the intensive farming of chickens or pigs. They are an efficient use of land; roughly six sheep can be kept on the amount that would suffice for a single cow or horse. Sheep can also consume plants, such as noxious weeds, that most other animals will not touch, and produce more young at a faster rate. Also, in contrast to most livestock species, the cost of raising sheep is not necessarily tied to the price of feed crops such as grain, soybeans and corn. Combined with the lower cost of quality sheep, all these factors combine to equal a lower overhead for sheep producers, thus entailing a higher profitability potential for the small farmer. Sheep are especially beneficial for independent producers, including family farms with limited resources, as the sheep industry is one of the few types of animal agriculture that has not been vertically integrated by agribusiness. However, small flocks, from 10 to 50 ewes, often are not profitable because they tend to be poorly managed. The primary reason is that mechanization is not feasible, so return per hour of labor is not maximized. Small farm flocks generally are used simply to control weeds on irrigation ditches or maintained as a hobby.
Shoulder of lamb
Sheep meat and milk were one of the earliest staple proteins consumed by human civilization after the transition from hunting and gathering to agriculture. Sheep meat prepared for food is known as either mutton or lamb, and approximately 540 million sheep are slaughtered each year for meat worldwide. "Mutton" is derived from the Old French moton, which was the word for sheep used by the Anglo-Norman rulers of much of the British Isles in the Middle Ages. This became the name for sheep meat in English, while the Old English word sceap was kept for the live animal. Throughout modern history, "mutton" has been limited to the meat of mature sheep usually at least two years of age; "lamb" is used for that of immature sheep less than a year.
In the 21st century, the nations with the highest consumption of sheep meat are the Arab states of the Persian Gulf, New Zealand, Australia, Greece, Uruguay, the United Kingdom and Ireland. These countries eat 14–40 lbs (3–18 kg) of sheep meat per capita, per annum. Sheep meat is also popular in France, Africa (especially the Arab world), the Caribbean, the rest of the Middle East, India, and parts of China. This often reflects a history of sheep production. In these countries in particular, dishes comprising alternative cuts and offal may be popular or traditional. Sheep testicles—called animelles or lamb fries—are considered a delicacy in many parts of the world. Perhaps the most unusual dish of sheep meat is the Scottish haggis, composed of various sheep innards cooked along with oatmeal and chopped onions inside its stomach. In comparison, countries such as the U.S. consume only a pound or less (under 0.5 kg), with Americans eating 50 pounds (22 kg) of pork and 65 pounds (29 kg) of beef. In addition, such countries rarely eat mutton, and may favor the more expensive cuts of lamb: mostly lamb chops and leg of lamb.
Though sheep's milk may be drunk rarely in fresh form, today it is used predominantly in cheese and yogurt making. Sheep have only two teats, and produce a far smaller volume of milk than cows. However, as sheep's milk contains far more fat, solids, and minerals than cow's milk, it is ideal for the cheese-making process. It also resists contamination during cooling better because of its much higher calcium content. Well-known cheeses made from sheep milk include the feta of Bulgaria and Greece, Roquefort of France, Manchego from Spain, the pecorino romano (the Italian word for "sheep" is pecore) and ricotta of Italy. Yogurts, especially some forms of strained yogurt, may also be made from sheep milk. Many of these products are now often made with cow's milk, especially when produced outside their country of origin. Sheep milk contains 4.8% lactose, which may affect those who are intolerant.
As with other domestic animals, the meat of uncastrated males is inferior in quality, especially as they grow. A "bucky" lamb is a lamb which was not castrated early enough, or which was castrated improperly (resulting in one testicle being retained). These lambs are worth less at market.
In science
Sheep are generally too large and reproduce too slowly to make ideal research subjects, and thus are not a common model organism. They have, however, played an influential role in some fields of science. In particular, the Roslin Institute of Edinburgh, Scotland used sheep for genetics research that produced groundbreaking results. In 1995, two ewes named Megan and Morag were the first mammals cloned from differentiated cells, also referred to as gynomerogony. A year later, a Finnish Dorset sheep named Dolly, dubbed "the world's most famous sheep" in Scientific American, was the first mammal to be cloned from an adult somatic cell. Following this, Polly and Molly were the first mammals to be simultaneously cloned and transgenic.
As of 2008, the sheep genome has not been fully sequenced, although a detailed genetic map has been published, and a draft version of the complete genome produced by assembling sheep DNA sequences using information given by the genomes of other mammals. In 2012, a transgenic sheep named "Peng Peng" was cloned by Chinese scientists, who spliced his genes with that of a roundworm (C. elegans) in order to increase production of fats healthier for human consumption.
In the study of natural selection, the population of Soay sheep that remain on the island of Hirta have been used to explore the relation of body size and coloration to reproductive success. Soay sheep come in several colors, and researchers investigated why the larger, darker sheep were in decline; this occurrence contradicted the rule of thumb that larger members of a population tend to be more successful reproductively. The feral Soays on Hirta are especially useful subjects because they are isolated.
Domestic sheep are sometimes used in medical research, particularly for researching cardiovascular physiology, in areas such as hypertension and heart failure. Pregnant sheep are also a useful model for human pregnancy, and have been used to investigate the effects on fetal development of malnutrition and hypoxia. In behavioral sciences, sheep have been used in isolated cases for the study of facial recognition, as their mental process of recognition is qualitatively similar to humans.
Cultural impact
Sheep have had a strong presence in many cultures, especially in areas where they form the most common type of livestock. In the English language, to call someone a sheep or ovine may allude that they are timid and easily led. In contradiction to this image, male sheep are often used as symbols of virility and power; the logos of the Los Angeles Rams football team and the Dodge Ram pickup truck allude to males of the bighorn sheep, Ovis canadensis.
Counting sheep is popularly said to be an aid to sleep, and some ancient systems of counting sheep persist today. Sheep also enter in colloquial sayings and idiom frequently with such phrases as "black sheep". To call an individual a black sheep implies that they are an odd or disreputable member of a group. This usage derives from the recessive trait that causes an occasional black lamb to be born into an entirely white flock. These black sheep were considered undesirable by shepherds, as black wool is not as commercially viable as white wool. Citizens who accept overbearing governments have been referred to by the Portmanteau neologism of sheeple. Somewhat differently, the adjective "sheepish" is also used to describe embarrassment.
In heraldry
In British heraldry, sheep appear in the form of rams, sheep proper and lambs. These are distinguished by the ram being depicted with horns and a tail, the sheep with neither and the lamb with its tail only. A further variant of the lamb, termed the Paschal lamb, is depicted as carrying a Christian cross and with a halo over its head. Rams' heads, portrayed without a neck and facing the viewer, are also found in British armories. The fleece, depicted as an entire sheepskin carried by a ring around its midsection, originally became known through its use in the arms of the Order of the Golden Fleece and was later adopted by towns and individuals with connections to the wool industry. A sheep on a blue field is depicted on the greater/royal arms of the king of Denmark to represent the Faroe Islands. In 2004 a modernized arms has been adopted by the Faroe Islands, which based on a 15th century coat of arms.
Religion and folklore
In antiquity, symbolism involving sheep cropped up in religions in the ancient Near East, the Mideast, and the Mediterranean area: Çatalhöyük, ancient Egyptian religion, the Cana'anite and Phoenician tradition, Judaism, Greek religion, and others. Religious symbolism and ritual involving sheep began with some of the first known faiths: Skulls of rams (along with bulls) occupied central placement in shrines at the Çatalhöyük settlement in 8,000 BCE. In Ancient Egyptian religion, the ram was the symbol of several gods: Khnum, Heryshaf and Amun (in his incarnation as a god of fertility). Other deities occasionally shown with ram features include the goddess Ishtar, the Phoenician god Baal-Hamon, and the Babylonian god Ea-Oannes. In Madagascar, sheep were not eaten as they were believed to be incarnations of the souls of ancestors.
There are many ancient Greek references to sheep: that of Chrysomallos, the golden-fleeced ram, continuing to be told through into the modern era. Astrologically, Aries, the ram, is the first sign of the classical Greek zodiac, and the sheep is the eighth of the twelve animals associated with the 12-year cycle of in the Chinese zodiac, related to the Chinese calendar. It is said in Chinese traditions that Hou ji sacrificed sheep. Mongolia, shagai are an ancient form of dice made from the cuboid bones of sheep that are often used for fortunetelling purposes.
Sheep play an important role in all the Abrahamic faiths; Abraham, Isaac, Jacob, Moses, and King David were all shepherds. According to the Biblical story of the Binding of Isaac, a ram is sacrificed as a substitute for Isaac after an angel stays Abraham's hand (in the Islamic tradition, Abraham was about to sacrifice Ishmael). Eid al-Adha is a major annual festival in Islam in which sheep (or other animals) are sacrificed in remembrance of this act. Sheep are occasionally sacrificed to commemorate important secular events in Islamic cultures. Greeks and Romans sacrificed sheep regularly in religious practice, and Judaism once sacrificed sheep as a Korban (sacrifice), such as the Passover lamb. Ovine symbols—such as the ceremonial blowing of a shofar—still find a presence in modern Judaic traditions.
Collectively, followers of Christianity are often referred to as a flock, with Christ as the Good Shepherd, and sheep are an element in the Christian iconography of the birth of Jesus. Some Christian saints are considered patrons of shepherds, and even of sheep themselves. Christ is also portrayed as the Sacrificial lamb of God (Agnus Dei) and Easter celebrations in Greece and Romania traditionally feature a meal of Paschal lamb. A church leader is often called the pastor, which is derived from the Latin word for shepherd. In many western Christian traditions bishops carry a staff, which also serves as a symbol of the episcopal office, known as a crosier, which is modeled on the shepherd's crook.
Sheep are key symbols in fables and nursery rhymes like The Wolf in Sheep's Clothing, Little Bo Peep, Baa, Baa, Black Sheep, and Mary Had a Little Lamb; novels such as George Orwell's Animal Farm and Haruki Murakami's A Wild Sheep Chase; songs such as Bach's Sheep may safely graze (Schafe können sicher weiden) and Pink Floyd's "Sheep", and poems like William Blake's "The Lamb".

Hyderabad (Listeni/ˈhaɪdərəˌbæd/ HY-dər-ə-bad; often /ˈhaɪdrəˌbæd/) is the capital of the southern Indian state of Telangana and de jure capital of Andhra Pradesh. Occupying 625 square kilometres along the banks of the Musi River, it has a population of about 6.8 million and a metropolitan population of about 7.75 million, making it the fourth most populous city and sixth most populous urban agglomeration in India. At an average altitude of 542 metres, much of Hyderabad is situated on hilly terrain around artificial lakes, including Hussain Sagar - predating the city's founding - north of the city centre.
Established in 1591 by Muhammad Quli Qutb Shah, Hyderabad remained under the rule of the Qutb Shahi dynasty for nearly a century before the Mughals captured the region. In 1724, Mughal viceroy Asif Jah I declared his sovereignty and created his own dynasty, known as the Nizams of Hyderabad. The Nizam's dominions became a princely state during the British Raj, and remained so for 150 years, with the city serving as its capital. The city continued as the capital of Hyderabad State after it was brought into the Indian Union in 1948, and became the capital of Andhra Pradesh after the States Reorganisation Act, 1956. Since 1956, Rashtrapati Nilayam in the city has been the winter office of the President of India. In 2014, the newly formed state of Telangana split from Andhra Pradesh and the city became joint capital of the two states, a transitional arrangement scheduled to end by 2025.
Relics of Qutb Shahi and Nizam rule remain visible today, with the Charminar - commissioned by Muhammad Quli Qutb Shah - coming to symbolise Hyderabad. Golconda fort is another major landmark. The influence of Mughlai culture is also evident in the city's distinctive cuisine, which includes Hyderabadi biryani and Hyderabadi haleem. The Qutb Shahis and Nizams established Hyderabad as a cultural hub, attracting men of letters from different parts of the world. Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire in the mid-19th century, with artists migrating to the city from the rest of the Indian subcontinent. While Hyderabad is losing its cultural pre-eminence, it is today, due to the Telugu film industry, the country's second-largest producer of motion pictures.
Hyderabad was historically known as a pearl and diamond trading centre, and it continues to be known as the City of Pearls. Many of the city's traditional bazaars, including Laad Bazaar, Begum Bazaar and Sultan Bazaar, have remained open for centuries. However, industrialisation throughout the 20th century attracted major Indian manufacturing, research and financial institutions, including Bharat Heavy Electricals Limited, the National Geophysical Research Institute and the Centre for Cellular and Molecular Biology. Special economic zones dedicated to information technology have encouraged companies from across India and around the world to set up operations and the emergence of pharmaceutical and biotechnology industries in the 1990s led to the area's naming as India's "Genome Valley". With an output of US$74 billion, Hyderabad is the fifth-largest contributor to India's overall gross domestic product.
HISTORY
TOPONYMY
According to John Everett-Heath, the author of Oxford Concise Dictionary of World Place Names, Hyderabad means "Haydar's city" or "lion city", from haydar (lion) and ābād (city). It was named to honour the Caliph Ali Ibn Abi Talib, who was also known as Haydar because of his lion-like valour in battles. Andrew Petersen, a scholar of Islamic architecture, says the city was originally called Baghnagar (city of gardens). One popular theory suggests that Muhammad Quli Qutb Shah, the founder of the city, named it "Bhaganagar" or "Bhāgnagar" after Bhagmati, a local nautch (dancing) girl with whom he had fallen in love. She converted to Islam and adopted the title Hyder Mahal. The city was renamed Hyderabad in her honour. According to another source, the city was named after Haidar, the son of Quli Qutb Shah.
EARLY AND MEDIEVAL HISTORY
Archaeologists excavating near the city have unearthed Iron Age sites that may date from 500 BCE. The region comprising modern Hyderabad and its surroundings was known as Golkonda ("shepherd's hill"), and was ruled by the Chalukya dynasty from 624 CE to 1075 CE. Following the dissolution of the Chalukya empire into four parts in the 11th century, Golkonda came under the control of the Kakatiya dynasty from 1158, whose seat of power was at Warangal, 148 km northeast of modern Hyderabad.
The Kakatiya dynasty was reduced to a vassal of the Khilji dynasty in 1310 after its defeat by Sultan Alauddin Khilji of the Delhi Sultanate. This lasted until 1321, when the Kakatiya dynasty was annexed by Malik Kafur, Allaudin Khilji's general. During this period, Alauddin Khilji took the Koh-i-Noor diamond, which is said to have been mined from the Kollur Mines of Golkonda, to Delhi. Muhammad bin Tughluq succeeded to the Delhi sultanate in 1325, bringing Warangal under the rule of the Tughlaq dynasty until 1347 when Ala-ud-Din Bahman Shah, a governor under bin Tughluq, rebelled against Delhi and established the Bahmani Sultanate in the Deccan Plateau, with Gulbarga, 200 km west of Hyderabad, as its capital. The Bahmani kings ruled the region until 1518 and were the first independent Muslim rulers of the Deccan.
Sultan Quli, a governor of Golkonda, revolted against the Bahmani Sultanate and established the Qutb Shahi dynasty in 1518; he rebuilt the mud-fort of Golconda and named the city "Muhammad nagar". The fifth sultan, Muhammad Quli Qutb Shah, established Hyderabad on the banks of the Musi River in 1591, to avoid the water shortages experienced at Golkonda. During his rule, he had the Charminar and Mecca Masjid built in the city. On 21 September 1687, the Golkonda Sultanate came under the rule of the Mughal emperor Aurangzeb after a year-long siege of the Golkonda fort. The annexed area was renamed Deccan Suba (Deccan province) and the capital was moved from Golkonda to Aurangabad, about 550 km northwest of Hyderabad.
MODERN HISTORY
In 1713 Farrukhsiyar, the Mughal emperor, appointed Asif Jah I to be Viceroy of the Deccan, with the title Nizam-ul-Mulk (Administrator of the Realm). In 1724, Asif Jah I defeated Mubariz Khan to establish autonomy over the Deccan Suba, named the region Hyderabad Deccan, and started what came to be known as the Asif Jahi dynasty. Subsequent rulers retained the title Nizam ul-Mulk and were referred to as Asif Jahi Nizams, or Nizams of Hyderabad. The death of Asif Jah I in 1748 resulted in a period of political unrest as his sons, backed by opportunistic neighbouring states and colonial foreign forces, contended for the throne. The accession of Asif Jah II, who reigned from 1762 to 1803, ended the instability. In 1768 he signed the treaty of Masulipatnam, surrendering the coastal region to the East India Company in return for a fixed annual rent.
In 1769 Hyderabad city became the formal capital of the Nizams. In response to regular threats from Hyder Ali (Dalwai of Mysore), Baji Rao I (Peshwa of the Maratha Empire), and Basalath Jung (Asif Jah II's elder brother, who was supported by the Marquis de Bussy-Castelnau), the Nizam signed a subsidiary alliance with the East India Company in 1798, allowing the British Indian Army to occupy Bolarum (modern Secunderabad) to protect the state's borders, for which the Nizams paid an annual maintenance to the British.
Until 1874 there were no modern industries in Hyderabad. With the introduction of railways in the 1880s, four factories were built to the south and east of Hussain Sagar lake, and during the early 20th century, Hyderabad was transformed into a modern city with the establishment of transport services, underground drainage, running water, electricity, telecommunications, universities, industries, and Begumpet Airport. The Nizams ruled their princely state from Hyderabad during the British Raj.
After India gained independence, the Nizam declared his intention to remain independent rather than become part of the Indian Union. The Hyderabad State Congress, with the support of the Indian National Congress and the Communist Party of India, began agitating against Nizam VII in 1948. On 17 September that year, the Indian Army took control of Hyderabad State after an invasion codenamed Operation Polo. With the defeat of his forces, Nizam VII capitulated to the Indian Union by signing an Instrument of Accession, which made him the Rajpramukh (Princely Governor) of the state until 31 October 1956. Between 1946 and 1951, the Communist Party of India fomented the Telangana uprising against the feudal lords of the Telangana region. The Constitution of India, which became effective on 26 January 1950, made Hyderabad State one of the part B states of India, with Hyderabad city continuing to be the capital. In his 1955 report Thoughts on Linguistic States, B. R. Ambedkar, then chairman of the Drafting Committee of the Indian Constitution, proposed designating the city of Hyderabad as the second capital of India because of its amenities and strategic central location. Since 1956, the Rashtrapati Nilayam in Hyderabad has been the second official residence and business office of the President of India; the President stays once a year in winter and conducts official business particularly relating to Southern India.
On 1 November 1956 the states of India were reorganised by language. Hyderabad state was split into three parts, which were merged with neighbouring states to form the modern states of Maharashtra, Karnataka and Andhra Pradesh. The nine Telugu- and Urdu-speaking districts of Hyderabad State in the Telangana region were merged with the Telugu-speaking Andhra State to create Andhra Pradesh,with Hyderabad as its capital. Several protests, known collectively as the Telangana movement, attempted to invalidate the merger and demanded the creation of a new Telangana state. Major actions took place in 1969 and 1972, and a third began in 2010. The city suffered several explosions: one at Dilsukhnagar in 2002 claimed two lives; terrorist bombs in May and August 2007 caused communal tension and riots; and two bombs exploded in February 2013. On 30 July 2013 the United Progressive Alliance (UPA) government of India declared that part of Andhra Pradesh would be split off to form a new Telangana state, and that Hyderabad city would be the capital city and part of Telangana, while the city would also remain the capital of Andhra Pradesh for no more than ten years. On 3 October 2013 the Union Cabinet approved the proposal, and in February 2014 both houses of Parliament passed the Telangana Bill. With the final assent of the President of India in June 2014, Telangana state was formed.
GEOGRAPHY
TOPOGRAPHY
Situated in the southern part of Telangana in southeastern India, Hyderabad is 1,566 kilometres south of Delhi, 699 kilometres southeast of Mumbai, and 570 kilometres north of Bangalore by road. It lies on the banks of the Musi River, in the northern part of the Deccan Plateau. Greater Hyderabad covers 625 km2, making it one of the largest metropolitan areas in India. With an average altitude of 542 metres, Hyderabad lies on predominantly sloping terrain of grey and pink granite, dotted with small hills, the highest being Banjara Hills at 672 metres. The city has numerous lakes referred to as sagar, meaning "sea". Examples include artificial lakes created by dams on the Musi, such as Hussain Sagar (built in 1562 near the city centre), Osman Sagar and Himayat Sagar. As of 1996, the city had 140 lakes and 834 water tanks (ponds).
CLIMATE
Hyderabad has a tropical wet and dry climate (Köppen Aw) bordering on a hot semi-arid climate (Köppen BSh). The annual mean temperature is 26.6 °C; monthly mean temperatures are 21–33 °C. Summers (March–June) are hot and humid, with average highs in the mid-to-high 30s Celsius; maximum temperatures often exceed 40 °C between April and June. The coolest temperatures occur in December and January, when the lowest temperature occasionally dips to 10 °C. May is the hottest month, when daily temperatures range from 26 to 39 °C; December, the coldest, has temperatures varying from 14.5 to 28 °C.
Heavy rain from the south-west summer monsoon falls between June and September, supplying Hyderabad with most of its mean annual rainfall. Since records began in November 1891, the heaviest rainfall recorded in a 24-hour period was 241.5 mm on 24 August 2000. The highest temperature ever recorded was 45.5 °C on 2 June 1966, and the lowest was 6.1 °C on 8 January 1946. The city receives 2,731 hours of sunshine per year; maximum daily sunlight exposure occurs in February.
CONSERVATION
Hyderabad's lakes and the sloping terrain of its low-lying hills provide habitat for an assortment of flora and fauna. The forest region in and around the city encompasses areas of ecological and biological importance, which are preserved in the form of national parks, zoos, mini-zoos and a wildlife sanctuary. Nehru Zoological Park, the city's one large zoo, is the first in India to have a lion and tiger safari park. Hyderabad has three national parks (Mrugavani National Park, Mahavir Harina Vanasthali National Park and Kasu Brahmananda Reddy National Park), and the Manjira Wildlife Sanctuary is about 50 km from the city. Hyderabad's other environmental reserves are: Kotla Vijayabhaskara Reddy Botanical Gardens, Shamirpet Lake, Hussain Sagar, Fox Sagar Lake, Mir Alam Tank and Patancheru Lake, which is home to regional birds and attracts seasonal migratory birds from different parts of the world. Organisations engaged in environmental and wildlife preservation include the Telangana Forest Department, Indian Council of Forestry Research and Education, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the Animal Welfare Board of India, the Blue Cross of Hyderabad and the University of Hyderabad.
ADMINISTRATION
COMMON CAPITAL OF TELANGANA AND ANDHRA PRADESH
According to the Andhra Pradesh Reorganisation Act, 2014 part 2 Section 5: "On and from the appointed day, Hyderabad in the existing State of Andhra Pradesh, shall be the common capital of the State of Telangana and the State of Andhra Pradesh for such period not exceeding ten years. After expiry of the period referred to in sub-section, Hyderabad shall be the capital of the State of Telangana and there shall be a new capital for the State of Andhra Pradesh."
The same sections also define that the common capital includes the existing area designated as the Greater Hyderabad Municipal Corporation under the Hyderabad Municipal Corporation Act, 1955. As stipulated in sections 3 and 18 of the Reorganisation Act, city MLAs are members of Telangana state assembly.
LOCAL GOVERNMENT
The Greater Hyderabad Municipal Corporation (GHMC) oversees the civic infrastructure of the city's 18 "circles", which together encompass 150 municipal wards. Each ward is represented by a corporator, elected by popular vote. The corporators elect the Mayor, who is the titular head of GHMC; executive powers rest with the Municipal Commissioner, appointed by the state government. The GHMC carries out the city's infrastructural work such as building and maintenance of roads and drains, town planning including construction regulation, maintenance of municipal markets and parks, solid waste management, the issuing of birth and death certificates, the issuing of trade licences, collection of property tax, and community welfare services such as mother and child healthcare, and pre-school and non-formal education. The GHMC was formed in April 2007 by merging the Municipal Corporation of Hyderabad (MCH) with 12 municipalities of the Hyderabad, Ranga Reddy and Medak districts covering a total area of 625 km2. In the 2009 municipal election, an alliance of the Indian National Congress and Majlis-e-Ittehadul Muslimeen formed the majority. The Secunderabad Cantonment Board is a civic administration agency overseeing an area of 40.1 km2, where there are several military camps. The Osmania University campus is administered independently by the university authority.
Law and order in Hyderabad city is supervised by the governor of Telangana. The jurisdiction is divided into two police commissionerates: Hyderabad and Cyberabad, which are again divided into four and five police zones respectively. Each zone is headed by a deputy commissioner.
The jurisdictions of the city's administrative agencies are, in ascending order of size: the Hyderabad Police area, Hyderabad district, the GHMC area ("Hyderabad city") and the area under the Hyderabad Metropolitan Development Authority (HMDA). The HMDA is an apolitical urban planning agency that covers the GHMC and its suburbs, extending to 54 mandals in five districts encircling the city. It coordinates the development activities of GHMC and suburban municipalities and manages the administration of bodies such as the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB).
As the seat of the government of Telangana, Hyderabad is home to the state's legislature, secretariat and high court, as well as various local government agencies. The Lower City Civil Court and the Metropolitan Criminal Court are under the jurisdiction of the High Court. The GHMC area contains 24 State Legislative Assembly constituencies, which form five constituencies of the Lok Sabha (the lower house of the Parliament of India).
UTILITY SERVICES
The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.
POLLUTION CONTROL
Hyderabad produces around 4,500 tonnes of solid waste daily, which is transported from collection units in Imlibun, Yousufguda and Lower Tank Bund to the dumpsite in Jawaharnagar. Disposal is managed by the Integrated Solid Waste Management project which was started by the GHMC in 2010. Rapid urbanisation and increased economic activity has also led to increased industrial waste, air, noise and water pollution, which is regulated by the Telangana Pollution Control Board (TPCB). The contribution of different sources to air pollution in 2006 was: 20–50% from vehicles, 40–70% from a combination of vehicle discharge and road dust, 10–30% from industrial discharges and 3–10% from the burning of household rubbish. Deaths resulting from atmospheric particulate matter are estimated at 1,700–3,000 each year. Ground water around Hyderabad, which has a hardness of up to 1000 ppm, around three times higher than is desirable, is the main source of drinking water but the increasing population and consequent increase in demand has led to a decline in not only ground water but also river and lake levels. This shortage is further exacerbated by inadequately treated effluent discharged from industrial treatment plants polluting the water sources of the city.
HEALTHCARE
The Commissionerate of Health and Family Welfare is responsible for planning, implementation and monitoring of all facilities related to health and preventive services. As of 2010–11, the city had 50 government hospitals, 300 private and charity hospitals and 194 nursing homes providing around 12,000 hospital beds, fewer than half the required 25,000. For every 10,000 people in the city, there are 17.6 hospital beds, 9 specialist doctors, 14 nurses and 6 physicians. The city also has about 4,000 individual clinics and 500 medical diagnostic centres. Private clinics are preferred by many residents because of the distance to, poor quality of care at and long waiting times in government facilities, despite the high proportion of the city's residents being covered by government health insurance: 24% according to a National Family Health Survey in 2005. As of 2012, many new private hospitals of various sizes were opened or being built. Hyderabad also has outpatient and inpatient facilities that use Unani, homeopathic and Ayurvedic treatments.
In the 2005 National Family Health Survey, it was reported that the city's total fertility rate is 1.8, which is below the replacement rate. Only 61% of children had been provided with all basic vaccines (BCG, measles and full courses of polio and DPT), fewer than in all other surveyed cities except Meerut. The infant mortality rate was 35 per 1,000 live births, and the mortality rate for children under five was 41 per 1,000 live births. The survey also reported that a third of women and a quarter of men are overweight or obese, 49% of children below 5 years are anaemic, and up to 20% of children are underweight, while more than 2% of women and 3% of men suffer from diabetes.
DEMOGRAPHICS
When the GHMC was created in 2007, the area occupied by the municipality increased from 175 km2 to 625 km2. Consequently, the population increased by 87%, from 3,637,483 in the 2001 census to 6,809,970 in the 2011 census, 24% of which are migrants from elsewhere in India, making Hyderabad the nation's fourth most populous city. As of 2011, the population density is 18,480/km2. At the same 2011 census, the Hyderabad Urban Agglomeration had a population of 7,749,334, making it the sixth most populous urban agglomeration in the country. The population of the Hyderabad urban agglomeration has since been estimated by electoral officials to be 9.1 million as of early 2013 but is expected to exceed 10 million by the end of the year. There are 3,500,802 male and 3,309,168 female citizens - a sex ratio of 945 females per 1000 males, higher than the national average of 926 per 1000. Among children aged 0–6 years, 373,794 are boys and 352,022 are girls - a ratio of 942 per 1000. Literacy stands at 82.96% (male 85.96%; female 79.79%), higher than the national average of 74.04%. The socio-economic strata consist of 20% upper class, 50% middle class and 30% working class.
ETHNIC GROUPS, LANGUAGE AND RELIGION
Referred to as "Hyderabadi", residents of Hyderabad are predominantly Telugu and Urdu speaking people, with minority Bengali, Gujarati (including Memon), Kannada (including Nawayathi), Malayalam, Marathi, Marwari, Odia, Punjabi, Tamil and Uttar Pradeshi communities. Hadhrami Arabs, African Arabs, Armenians, Abyssinians, Iranians, Pathans and Turkish people are also present; these communities, of which the Hadhrami are the largest, declined after Hyderabad State became part of the Indian Union, as they lost the patronage of the Nizams.
Telugu is the official language of Hyderabad and Urdu is its second language. The Telugu dialect spoken in Hyderabad is called Telangana, and the Urdu spoken is called Dakhani. English is also used. A significant minority speak other languages, including Hindi, Marathi, Odia, Tamil, Bengali and Kannada.
Hindus are in the majority. Muslims are present throughout the city and predominate in and around the Old City. There are also Christian, Sikh, Jain, Buddhist and Parsi communities and iconic temples, mosques and churches can be seen. According to the 2001 census, Hyderabad district's religious make-up was: Hindus (55.41%), Muslims (41.17%), Christians (2.43%), Jains (0.43%), Sikhs (0.29%) and Buddhists (0.02%); 0.23% did not state any religion.
SLUMS
In the greater metropolitan area, 13% of the population live below the poverty line. According to a 2012 report submitted by GHMC to the World Bank, Hyderabad has 1,476 slums with a total population of 1.7 million, of whom 66% live in 985 slums in the "core" of the city (the part that formed Hyderabad before the April 2007 expansion) and the remaining 34% live in 491 suburban tenements. About 22% of the slum-dwelling households had migrated from different parts of India in the last decade of the 20th century, and 63% claimed to have lived in the slums for more than 10 years. Overall literacy in the slums is 60–80% and female literacy is 52–73%. A third of the slums have basic service connections, and the remainder depend on general public services provided by the government. There are 405 government schools, 267 government aided schools, 175 private schools and 528 community halls in the slum areas. According to a 2008 survey by the Centre for Good Governance, 87.6% of the slum-dwelling households are nuclear families, 18% are very poor, with an income up to ₹20000 (US$300) per annum, 73% live below the poverty line (a standard poverty line recognised by the Andhra Pradesh Government is ₹24000 (US$360) per annum), 27% of the chief wage earners (CWE) are casual labour and 38% of the CWE are illiterate. About 3.72% of the slum children aged 5–14 do not go to school and 3.17% work as child labour, of whom 64% are boys and 36% are girls. The largest employers of child labour are street shops and construction sites. Among the working children, 35% are engaged in hazardous jobs.
NEIGHBOURHOODS
The historic city established by Muhammad Quli Qutb Shah on the southern side of the Musi River forms the "Old City", while the "New City" encompasses the urbanised area on the northern banks. The two are connected by many bridges across the river, the oldest of which is Purana Pul ("old bridge"). Hyderabad is twinned with neighbouring Secunderabad, to which it is connected by Hussain Sagar.
Many historic and tourist sites lie in south central Hyderabad, such as the Charminar, the Mecca Masjid, the Salar Jung Museum, the Nizam's Museum, the Falaknuma Palace, and the traditional retail corridor comprising the Pearl Market, Laad Bazaar and Madina Circle. North of the river are hospitals, colleges, major railway stations and business areas such as Begum Bazaar, Koti, Abids, Sultan Bazaar and Moazzam Jahi Market, along with administrative and recreational establishments such as the Reserve Bank of India, the Telangana Secretariat, the Hyderabad Mint, the Telangana Legislature, the Public Gardens, the Nizam Club, the Ravindra Bharathi, the State Museum, the Birla Temple and the Birla Planetarium.
North of central Hyderabad lie Hussain Sagar, Tank Bund Road, Rani Gunj and the Secunderabad Railway Station. Most of the city's parks and recreational centres, such as Sanjeevaiah Park, Indira Park, Lumbini Park, NTR Gardens, the Buddha statue and Tankbund Park are located here. In the northwest part of the city there are upscale residential and commercial areas such as Banjara Hills, Jubilee Hills, Begumpet, Khairatabad and Miyapur. The northern end contains industrial areas such as Sanathnagar, Moosapet, Balanagar, Patancheru and Chanda Nagar. The northeast end is dotted with residential areas. In the eastern part of the city lie many defence research centres and Ramoji Film City. The "Cyberabad" area in the southwest and west of the city has grown rapidly since the 1990s. It is home to information technology and bio-pharmaceutical companies and to landmarks such as Hyderabad Airport, Osman Sagar, Himayath Sagar and Kasu Brahmananda Reddy National Park.
LANDMARKS
Heritage buildings constructed during the Qutb Shahi and Nizam eras showcase Indo-Islamic architecture influenced by Medieval, Mughal and European styles. After the 1908 flooding of the Musi River, the city was expanded and civic monuments constructed, particularly during the rule of Mir Osman Ali Khan (the VIIth Nizam), whose patronage of architecture led to him being referred to as the maker of modern Hyderabad. In 2012, the government of India declared Hyderabad the first "Best heritage city of India".
Qutb Shahi architecture of the 16th and early 17th centuries followed classical Persian architecture featuring domes and colossal arches. The oldest surviving Qutb Shahi structure in Hyderabad is the ruins of Golconda fort built in the 16th century. The Charminar, Mecca Masjid, Charkaman and Qutb Shahi tombs are other existing structures of this period. Among these the Charminar has become an icon of the city; located in the centre of old Hyderabad, it is a square structure with sides 20 m long and four grand arches each facing a road. At each corner stands a 56 m-high minaret. Most of the historical bazaars that still exist were constructed on the street north of Charminar towards Golconda fort. The Charminar, Qutb Shahi tombs and Golconda fort are considered to be monuments of national importance in India; in 2010 the Indian government proposed that the sites be listed for UNESCO World Heritage status.
Among the oldest surviving examples of Nizam architecture in Hyderabad is the Chowmahalla Palace, which was the seat of royal power. It showcases a diverse array of architectural styles, from the Baroque Harem to its Neoclassical royal court. The other palaces include Falaknuma Palace (inspired by the style of Andrea Palladio), Purani Haveli, King Kothi and Bella Vista Palace all of which were built at the peak of Nizam rule in the 19th century. During Mir Osman Ali Khan's rule, European styles, along with Indo-Islamic, became prominent. These styles are reflected in the Falaknuma Palace and many civic monuments such as the Hyderabad High Court, Osmania Hospital, Osmania University, the State Central Library, City College, the Telangana Legislature, the State Archaeology Museum, Jubilee Hall, and Hyderabad and Kachiguda railway stations. Other landmarks of note are Paigah Palace, Asman Garh Palace, Basheer Bagh Palace, Errum Manzil and the Spanish Mosque, all constructed by the Paigah family.
ECONOMY
Hyderabad is the largest contributor to the gross domestic product (GDP), tax and other revenues, of Telangana, and the sixth largest deposit centre and fourth largest credit centre nationwide, as ranked by the Reserve Bank of India (RBI) in June 2012. Its US$74 billion GDP made it the fifth-largest contributor city to India's overall GDP in 2011–12. Its per capita annual income in 2011 was ₹44300 (US$670). As of 2006, the largest employers in the city were the governments of Andhra Pradesh (113,098 employees) and India (85,155). According to a 2005 survey, 77% of males and 19% of females in the city were employed. The service industry remains dominant in the city, and 90% of the employed workforce is engaged in this sector.
Hyderabad's role in the pearl trade has given it the name "City of Pearls" and up until the 18th century, the city was also the only global trading centre for large diamonds. Industrialisation began under the Nizams in the late 19th century, helped by railway expansion that connected the city with major ports. From the 1950s to the 1970s, Indian enterprises, such as Bharat Heavy Electricals Limited (BHEL), Nuclear Fuel Complex (NFC), National Mineral Development Corporation (NMDC), Bharat Electronics (BEL), Electronics Corporation of India Limited (ECIL), Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL), Centre for Cellular and Molecular Biology (CCMB), Centre for DNA Fingerprinting and Diagnostics (CDFD), State Bank of Hyderabad (SBH) and Andhra Bank (AB) were established in the city. The city is home to Hyderabad Securities formerly known as Hyderabad Stock Exchange (HSE), and houses the regional office of the Securities and Exchange Board of India (SEBI). In 2013, the Bombay Stock Exchange (BSE) facility in Hyderabad was forecasted to provide operations and transactions services to BSE-Mumbai by the end of 2014. The growth of the financial services sector has helped Hyderabad evolve from a traditional manufacturing city to a cosmopolitan industrial service centre. Since the 1990s, the growth of information technology (IT), IT-enabled services (ITES), insurance and financial institutions has expanded the service sector, and these primary economic activities have boosted the ancillary sectors of trade and commerce, transport, storage, communication, real estate and retail.
Hyderabad's commercial markets are divided into four sectors: central business districts, sub-central business centres, neighbourhood business centres and local business centres. Many traditional and historic bazaars are located throughout the city, Laad Bazaar being the prominent among all is popular for selling a variety of traditional and cultural antique wares, along with gems and pearls.
The establishment of Indian Drugs and Pharmaceuticals Limited (IDPL), a public sector undertaking, in 1961 was followed over the decades by many national and global companies opening manufacturing and research facilities in the city. As of 2010, the city manufactured one third of India's bulk drugs and 16% of biotechnology products, contributing to its reputation as "India's pharmaceutical capital" and the "Genome Valley of India". Hyderabad is a global centre of information technology, for which it is known as Cyberabad (Cyber City). As of 2013, it contributed 15% of India's and 98% of Andhra Pradesh's exports in IT and ITES sectors and 22% of NASSCOM's total membership is from the city. The development of HITEC City, a township with extensive technological infrastructure, prompted multinational companies to establish facilities in Hyderabad. The city is home to more than 1300 IT and ITES firms, including global conglomerates such as Microsoft (operating its largest R&D campus outside the US), Google, IBM, Yahoo!, Dell, Facebook, and major Indian firms including Tech Mahindra, Infosys, Tata Consultancy Services (TCS), Polaris and Wipro. In 2009 the World Bank Group ranked the city as the second best Indian city for doing business. The city and its suburbs contain the highest number of special economic zones of any Indian city.
Like the rest of India, Hyderabad has a large informal economy that employs 30% of the labour force. According to a survey published in 2007, it had 40–50,000 street vendors, and their numbers were increasing. Among the street vendors, 84% are male and 16% female, and four fifths are "stationary vendors" operating from a fixed pitch, often with their own stall. Most are financed through personal savings; only 8% borrow from moneylenders. Vendor earnings vary from ₹50 (75¢ US) to ₹800 (US$12) per day. Other unorganised economic sectors include dairy, poultry farming, brick manufacturing, casual labour and domestic help. Those involved in the informal economy constitute a major portion of urban poor.
CULTURE
Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted. A further consequence of this north–south mix is that both Telugu and Urdu are official languages of Telangana.[164] The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims.
Traditional Hyderabadi garb also reveals a mix of Muslim and South Asian influences with men wearing sherwani and kurta - paijama and women wearing khara dupatta and salwar kameez. Muslim women also commonly wear burqas and hijabs in public. In addition to the traditional Indian and Muslim garments, increasing exposure to western cultures has led to a rise in the wearing of western style clothing among youths.
LITERATURE
In the past, Qutb Shahi rulers and Nizams attracted artists, architects and men of letters from different parts of the world through patronage. The resulting ethnic mix popularised cultural events such as mushairas (poetic symposia). The Qutb Shahi dynasty particularly encouraged the growth of Deccani Urdu literature leading to works such as the Deccani Masnavi and Diwan poetry, which are among the earliest available manuscripts in Urdu. Lazzat Un Nisa, a book compiled in the 15th century at Qutb Shahi courts, contains erotic paintings with diagrams for secret medicines and stimulants in the eastern form of ancient sexual arts. The reign of the Nizams saw many literary reforms and the introduction of Urdu as a language of court, administration and education. In 1824, a collection of Urdu Ghazal poetry, named Gulzar-e-Mahlaqa, authored by Mah Laqa Bai - the first female Urdu poet to produce a Diwan - was published in Hyderabad.
Hyderabad has continued with these traditions in its annual Hyderabad Literary Festival, held since 2010, showcasing the city's literary and cultural creativity. Organisations engaged in the advancement of literature include the Sahitya Akademi, the Urdu Academy, the Telugu Academy, the National Council for Promotion of Urdu Language, the Comparative Literature Association of India, and the Andhra Saraswata Parishad. Literary development is further aided by state institutions such as the State Central Library, the largest public library in the state which was established in 1891, and other major libraries including the Sri Krishna Devaraya Andhra Bhasha Nilayam, the British Library and the Sundarayya Vignana Kendram.
MUSIC AND FILMS
South Indian music and dances such as the Kuchipudi and Kathakali styles are popular in the Deccan region. As a result of their culture policies, North Indian music and dance gained popularity during the rule of the Mughals and Nizams, and it was also during their reign that it became a tradition among the nobility to associate themselves with tawaif (courtesans). These courtesans were revered as the epitome of etiquette and culture, and were appointed to teach singing, poetry and classical dance to many children of the aristocracy. This gave rise to certain styles of court music, dance and poetry. Besides western and Indian popular music genres such as filmi music, the residents of Hyderabad play city-based marfa music, dholak ke geet (household songs based on local Folklore), and qawwali, especially at weddings, festivals and other celebratory events. The state government organises the Golconda Music and Dance Festival, the Taramati Music Festival and the Premavathi Dance Festival to further encourage the development of music.
Although the city is not particularly noted for theatre and drama, the state government promotes theatre with multiple programmes and festivals in such venues as the Ravindra Bharati, Shilpakala Vedika and Lalithakala Thoranam. Although not a purely music oriented event, Numaish, a popular annual exhibition of local and national consumer products, does feature some musical performances. The city is home to the Telugu film industry, popularly known as Tollywood and as of 2012, produces the second largest number of films in India with the largest number being produced by Bollywood. Films in the local Hyderabadi dialect are also produced and have been gaining popularity since 2005. The city has also hosted international film festivals such as the International Children's Film Festival and the Hyderabad International Film Festival. In 2005, Guinness World Records declared Ramoji Film City to be the world's largest film studio.
ART AND HANDICRAFTS
The region is well known for its Golconda and Hyderabad painting styles which are branches of Deccani painting. Developed during the 16th century, the Golconda style is a native style blending foreign techniques and bears some similarity to the Vijayanagara paintings of neighbouring Mysore. A significant use of luminous gold and white colours is generally found in the Golconda style. The Hyderabad style originated in the 17th century under the Nizams. Highly influenced by Mughal painting, this style makes use of bright colours and mostly depicts regional landscape, culture, costumes and jewellery.
Although not a centre for handicrafts itself, the patronage of the arts by the Mughals and Nizams attracted artisans from the region to Hyderabad. Such crafts include: Bidriware, a metalwork handicraft from neighbouring Karnataka, which was popularised during the 18th century and has since been granted a Geographical Indication (GI) tag under the auspices of the WTO act; and Zari and Zardozi, embroidery works on textile that involve making elaborate designs using gold, silver and other metal threads. Another example of a handicraft drawn to Hyderabad is Kalamkari, a hand-painted or block-printed cotton textile that comes from cities in Andhra Pradesh. This craft is distinguished in having both a Hindu style, known as Srikalahasti and entirely done by hand, and an Islamic style, known as Machilipatnam that uses both hand and block techniques. Examples of Hyderabad's arts and crafts are housed in various museums including the Salar Jung Museum (housing "one of the largest one-man-collections in the world"), the AP State Archaeology Museum, the Nizam Museum, the City Museum and the Birla Science Museum.
CUISINE
Hyderabadi cuisine comprises a broad repertoire of rice, wheat and meat dishes and the skilled use of various spices. Hyderabadi biryani and Hyderabadi haleem, with their blend of Mughlai and Arab cuisines, have become iconic dishes of India. Hyderabadi cuisine is highly influenced by Mughlai and to some extent by French, Arabic, Turkish, Iranian and native Telugu and Marathwada cuisines. Other popular native dishes include nihari, chakna, baghara baingan and the desserts qubani ka meetha, double ka meetha and kaddu ki kheer (a sweet porridge made with sweet gourd).
MEDIA
One of Hyderabad's earliest newspapers, The Deccan Times, was established in the 1780s. In modern times, the major Telugu dailies published in Hyderabad are Eenadu, Andhra Jyothy, Sakshi and Namaste Telangana, while the major English papers are The Times of India, The Hindu and The Deccan Chronicle, and the major Urdu papers include The Siasat Daily, The Munsif Daily and Etemaad. Many coffee table magazines, professional magazines and research journals are also regularly published. The Secunderabad Cantonment Board established the first radio station in Hyderabad State around 1919. Deccan Radio was the first radio public broadcast station in the city starting on 3 February 1935, with FM broadcasting beginning in 2000. The available channels in Hyderabad include All India Radio, Radio Mirchi, Radio City, Red FM and Big FM.
Television broadcasting in Hyderabad began in 1974 with the launch of Doordarshan, the Government of India's public service broadcaster, which transmits two free-to-air terrestrial television channels and one satellite channel. Private satellite channels started in July 1992 with the launch of Star TV. Satellite TV channels are accessible via cable subscription, direct-broadcast satellite services or internet-based television. Hyderabad's first dial-up internet access became available in the early 1990s and was limited to software development companies. The first public internet access service began in 1995, with the first private sector internet service provider (ISP) starting operations in 1998. In 2015, high-speed public WiFi was introduced in parts of the city.
EDUCATION
Public and private schools in Hyderabad are governed by the Central Board of Secondary Education and follow a "10+2+3" plan. About two-thirds of pupils attend privately run institutions. Languages of instruction include English, Hindi, Telugu and Urdu. Depending on the institution, students are required to sit the Secondary School Certificate or the Indian Certificate of Secondary Education. After completing secondary education, students enroll in schools or junior colleges with a higher secondary facility. Admission to professional graduation colleges in Hyderabad, many of which are affiliated with either Jawaharlal Nehru Technological University Hyderabad (JNTUH) or Osmania University (OU), is through the Engineering Agricultural and Medical Common Entrance Test (EAM-CET).There are 13 universities in Hyderabad: two private universities, two deemed universities, six state universities and three central universities. The central universities are the University of Hyderabad, Maulana Azad National Urdu University and the English and Foreign Languages University. Osmania University, established in 1918, was the first university in Hyderabad and as of 2012 is India's second most popular institution for international students. The Dr. B. R. Ambedkar Open University, established in 1982, is the first distance learning open university in India.
Hyderabad is also home to a number of centres specialising in particular fields such as biomedical sciences, biotechnology and pharmaceuticals, such as the National Institute of Pharmaceutical Education and Research (NIPER) and National Institute of Nutrition (NIN). Hyderabad has five major medical schools - Osmania Medical College, Gandhi Medical College, Nizam's Institute of Medical Sciences, Deccan College of Medical Sciences and Shadan Institute of Medical Sciences - and many affiliated teaching hospitals.

Hyderabad has hosted many international cricket matches, including matches in the 1987 and the 1996 ICC Cricket World Cups. The Hyderabad cricket team represents the city in the Ranji Trophy - a first-class cricket tournament among India's states and cities. Hyderabad is also home to the Indian Premier League franchise Sunrisers Hyderabad. A previous franchise was the Deccan Chargers, which won the 2009 Indian Premier League held in South Africa.
During British rule, Secunderabad became a well-known sporting centre and many race courses, parade grounds and polo fields were built. Many elite clubs formed by the Nizams and the British such as the Secunderabad Club, the Nizam Club and the Hyderabad Race Club, which is known for its horse racing especially the annual Deccan derby, still exist. In more recent times, motorsports has become popular with the Andhra Pradesh Motor Sports Club organising popular events such as the Deccan 1/4 Mile Drag, TSD Rallies and 4x4 off-road rallying.

TRANSPORT
The most commonly used forms of medium distance transport in Hyderabad include government owned services such as light railways and buses, as well as privately operated taxis and auto rickshaws. Bus services operate from the Mahatma Gandhi Bus Station in the city centre and carry over 130 million passengers daily across the entire network. Hyderabad's light rail transportation system, the Multi-Modal Transport System (MMTS), is a three line suburban rail service used by over 160,000 passengers daily. Complementing these government services are minibus routes operated by Setwin (Society for Employment Promotion & Training in Twin Cities). Intercity rail services also operate from Hyderabad; the main, and largest, station is Secunderabad Railway Station, which serves as Indian Railways' South Central Railway zone headquarters and a hub for both buses and MMTS light rail services connecting Secunderabad and Hyderabad. Other major railway stations in Hyderabad are Hyderabad Deccan Station, Kachiguda Railway Station, Begumpet Railway Station, Malkajgiri Railway Station and Lingampally Railway Station. The Hyderabad Metro, a new rapid transit system, is to be added to the existing public transport infrastructure and is scheduled to operate three lines by 2015. As of 2012, there are over 3.5 million vehicles operating in the city, of which 74% are two-wheelers, 15% cars and 3% three-wheelers. The remaining 8% include buses, goods vehicles and taxis. The large number of vehicles coupled with relatively low road coverage - roads occupy only 9.5% of the total city area - has led to widespread traffic congestion especially since 80% of passengers and 60% of freight are transported by road. The Inner Ring Road, the Outer Ring Road, the Hyderabad Elevated Expressway, the longest flyover in India, and various interchanges, overpasses and underpasses were built to ease the congestion. Maximum speed limits within the city are 50 km/h for two-wheelers and cars, 35 km/h for auto rickshaws and 40 km/h for light commercial vehicles and buses.
Hyderabad sits at the junction of three National Highways linking it to six other states: NH-7 runs 2,369 km from Varanasi, Uttar Pradesh, in the north to Kanyakumari, Tamil Nadu, in the south; NH-9, runs 841 km east-west between Machilipatnam, Andhra Pradesh, and Pune, Maharashtra; and the 280 km NH-163 links Hyderabad to Bhopalpatnam, Chhattisgarh. Five state highways, SH-1, SH-2, SH-4, SH-5 and SH-6, either start from, or pass through, Hyderabad.
Air traffic was previously handled via Begumpet Airport, but this was replaced by Rajiv Gandhi International Airport (RGIA) (IATA: HYD, ICAO: VOHS) in 2008, with the capacity of handling 12 million passengers and 100,000 tonnes of cargo per annum. In 2011, Airports Council International, an autonomous body representing the world's airports, judged RGIA the world's best airport in the 5–15 million passenger category and the world's fifth best airport for service quality.

I dug this out on the day that I was set a personal programme at the gym by Kimble, the senior instructor. He makes no concessions for age, and it was very hard work.
I don't need cardiovascular exercises as I swim and walk a great deal, so it was all weights and resistance equipment.
I had hoped to lose my bar mitzvah flaps, and various other revolting loose bits.
This doodle was done during a boring meeting of some sort.
Compared to now, I look GORGEOUS in this scribble.
I am reposting this now to mark my return to the gym after a gap of some years, with the same aim in mind ! The new senior instructor is better qualified to assist older folk, and I hope to keep going for longer.
