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".

The Jerusalem artichoke (Helianthus tuberosus), also called sunroot, sunchoke, wild sunflower, topinambur, or earth apple, is a species of sunflower native to central North America. It is cultivated widely across the temperate zone for its tuber, which is used as a root vegetable.

 

Description

Helianthus tuberosus is a herbaceous perennial plant growing to 1.5–3 m (4 ft 11 in – 9 ft 10 in) tall with opposite leaves on the lower part of the stem but alternate towards the top. The leaves have a rough, hairy texture. Larger leaves on the lower stem are broad ovoid-acute and can be up to 30 cm (12 in) long. Leaves higher on the stem are smaller and narrower.

 

The flowers are yellow and produced in capitate flowerheads, which are 5–10 cm (2–4 in) in diameter, with 10–20 ray florets and 60 or more small disc florets. The flowers are briefly fragrant, giving off a light, vanilla-chocolate perfume.

 

The tubers are often elongated and uneven, typically 7.5–10 cm (3–3+7⁄8 in) long and 3–5 cm (1–2 in) thick, and vaguely resembling a ginger root in appearance, with a crisp and crunchy texture when raw. They vary in color from pale brown to white, red, or purple.

 

Food use

Before the arrival of Europeans, indigenous peoples cultivated H. tuberosus as a food source. The tubers persist for years after being planted, so the species expanded its range from central North America to the eastern and western regions.[citation needed] Early European colonists learned of this and sent tubers back to Europe, where they became a popular crop and naturalized there. It later gradually fell into obscurity in North America, but attempts to market it commercially were successful in the late 1900s and early 2000s.

 

The tuber contains about 2% protein, no oil, and little starch. It is rich in the carbohydrate inulin (8 to 13%), which is a polymer of the monosaccharide fructose. Tubers stored for any length of time convert their inulin into its component, fructose. Jerusalem artichokes have an underlying sweet taste because of the fructose, which is about one and a half times as sweet as sucrose.

 

It has also been reported as a folk remedy for diabetes: since inulin is not assimilated in the intestine, it doesn't cause a glycemic spike as potatoes would. Temperature variances have been shown to affect the amount of inulin the Jerusalem artichoke can produce. It makes less inulin in a colder region than when it is in a warmer region.

 

Etymology

Despite one of its names, the Jerusalem artichoke has no relationship to Jerusalem, and it is not a type of artichoke. though the two are distantly related as members of the daisy family. Italian settlers in the United States called the plant girasole, the Italian word for sunflower, because of its familial relationship to the garden sunflower (both plants are members of the genus Helianthus). Over time, the name girasole (pronounced closer to in southern Italian dialects) was corrupted by English-speakers to Jerusalem. An alternative explanation for the name is that the Puritans, when they came to the New World, named the plant with regard to the "New Jerusalem" they believed they were creating in the wilderness. Various other names have been applied to the plant, such as the French or Canada potato, topinambour, and lambchoke. Sunchoke, a name by which it is still known today, was invented in the 1960s by Frieda Caplan, a produce wholesaler trying to revive the plant's appeal.

 

The artichoke part of the Jerusalem artichoke's name comes from the taste of its edible tuber. Samuel de Champlain, the French explorer, sent the first samples of the plant to France, noting its taste was similar to that of an artichoke.

 

The name topinambur, in one account, dates from 1615, when a member of the Brazilian coastal tribe called the Tupinambá visited the Vatican at the same time that a sample of the tuber from Canada was on display there, presented as a critical food source that helped French Canadian settlers survive the winter. The New World connection resulted in the name topinambur being applied to the tuber, the word now used in French, German, Italian, Polish, Romanian, Russian, and Spanish.

 

History

Jerusalem artichokes were first cultivated by the Indigenous peoples of the Americas, though the exact native range of the species is unknown. Genome analysis has ruled out the common sunflower (also originating in the Americas) as an ancestor, and instead points to hybridization between the hairy sunflower and the sawtooth sunflower.

 

The French explorer Samuel de Champlain discovered that the native people of Nauset Harbor in Massachusetts had cultivated roots that tasted like artichoke. The following year, Champlain returned to the same area to discover that the roots had a flavor similar to chard and was responsible for bringing the plant back to France. Sometime later, Petrus Hondius, a Dutch botanist, planted a shriveled Jerusalem artichoke tuber in his garden at Terneuzen and was surprised to see the plant proliferate. Jerusalem artichokes are so well-suited for the European climate and soil that the plant multiplies quickly. By the mid-1600s, the Jerusalem artichoke had become a very common vegetable for human consumption in Europe and the Americas and was also used for livestock feed in Europe and colonial America. The French were particularly fond of the vegetable, which reached its peak popularity at the turn of the 19th century. The Jerusalem artichoke was titled 'best soup vegetable' in the 2002 Nice Festival for the Heritage of French Cuisine.

 

The French explorer and Acadia's first historian Marc Lescarbot described Jerusalem artichokes as being "as big as turnips or truffles," suitable for eating and taste "like chards, but more pleasant." In 1629, the English herbalist and botanist John Parkinson wrote that the widely grown Jerusalem artichoke had become very common and cheap in London, so much so "that even the most vulgar begin to despise them." In contrast, when they had first arrived in England, the tubers had been "dainties for the Queen."

 

Biological characteristics

Its rapid growth and its ability to reproduce from buried rhizomes and tubers facilitates the Jerusalem artichoke's uncontrolled spread.The vegetative propagules can be transported via rivers and water streams and begin a new population on riverbanks. Dispersal by animal is also possible, as animals feed on tubers and rhizomes and excrete the propagules in new areas. With humans' cultivation, there is also a risk of the plant's unintended escape into the wild. It can also be propagated by seed. Its relatively long flower period enables the Jerusalem artichoke to increase its reproductive potential.

 

Origins and distribution

Originated in North America the Jerusalem artichoke can now be found in several countries in North and South America, Europe, Asia, and Australia. In Central Europe it is one of the most expanding invasive plant species. It can grow in many geo-climatic regions and different types of soils. However, Jerusalem artichoke prefers moist habitats and seems to be less tolerant of dry conditions.

 

Suppression of native plant species

Because of its ecological and biological attributes, the Jerusalem artichoke is highly competitive with other plant species. For instance, the carbohydrates in the tubers serve as an energy source for rapid growth in spring .The plant expands rapidly and creates shading, which has a suppressing effect on neighbouring plants. Therefore, the risk of outcompeting and repressing the growth of native plants is increased.

 

Cultivation and use

erusalem artichoke tuber collage

Unlike most tubers, but in common with many other members of the Asteraceae (including the artichoke), Jerusalem artichoke tubers store their carbohydrate as inulin (not to be confused with insulin) rather than as starch. This has made them an important source of inulin used as a dietary fiber in food manufacturing.

 

Jerusalem artichoke can propagate with seeds and tubers but the use of tubers leads to higher yields. For planting, the tubers are cut into pieces with three to five buds that are placed in 5–10 cm depth in the soil. Jerusalem artichoke has low nutrient requirements and needs less nitrogen than other energy crops. The competitiveness against weeds is high, making weed control easier but also making it harder to grow a different culture afterward, since usually small pieces of tubers remain in the ground after harvest. The plant's high competitiveness may be due to allelopathic effects, high plant size, and rapid growth rate.

 

Crop yields are high, typically 16–20 tonnes per hectare (7–9 short ton/acre) for tubers, and 18–28 tonnes per hectare (8–12 short ton/acre) green weight for foliage. Tubers remaining in the ground lie dormant over winter and can handle temperatures as low as −30 °C (−22 °F).[49] Jerusalem artichoke also has potential for production of ethanol fuel, using inulin-adapted strains of yeast for fermentation.

 

The tubers are used for cooking and baking in the same ways as potatoes, but unlike the potato, they can also be eaten raw. They have a similar consistency and, in their raw form, have a similar texture but a sweeter, nuttier flavor. When raw and sliced thinly, they are fit for a salad. Their inulin form of carbohydrates give the tubers a tendency to become soft and mushy if boiled, but they retain their texture better when steamed. The inulin cannot be broken down by the human digestive system but bacteria metabolize it in the colon. This can cause flatulence and, in some cases, gastric pain. John Gerard's Herbal, printed in 1621, quotes the English botanist John Goodyer on Jerusalem artichokes:

 

which way soever they be dressed and eaten, they stir and cause a filthy loathsome stinking wind within the body, thereby causing the belly to be pained and tormented, and are a meat more fit for swine than men.

 

Jerusalem artichokes have 650 mg potassium per 1 cup (150 g) serving. They are also high in iron and contain 10–12% of the USRDA of fiber, niacin, thiamine, phosphorus, and copper.

 

Use as forage

In former times, Jerusalem artichoke was used as forage for domesticated cattle, horses, and pigs. The plant has valuable nutrient contents and various bioactive compounds, and so is used today as an animal feed source or for the health of several animal species. Pigs, for example, can eat the tuber either dried or directly from the ground or the green plant biomass (stalks and leaves) from the pasture. Washed Jerusalem artichoke tubers can be fed to many animals, and silage produced from the harvested stalks and leaves. The silage has high nutrient values and satisfactory digestion performance for ruminants. Its high inulin content beneficially affects the rumen metabolism and microflora. However, cutting the tops to produce silage greatly reduces the harvest of the tubers. There are also many other Jerusalem artichoke products on the market, such as supplementary feed for horses, dogs, and small animals.

Fermented products

In Baden-Württemberg, Germany, over 90% of the Jerusalem artichoke crop is used to produce a spirit called Topinambur, the German word for Jerusalem artichoke. By the end of the 19th century, the tubers were being used in Baden to make a spirit called "Topinambur-Branntwein" (Jerusalem artichoke brandy), "Topinambur" (Jerusalem artichoke), "Topi","Erdäpfler","Rossler", or "Borbel". Topinambur produced in the European Union and Switzerland must be made exclusively from Jerusalem artichokes, contain at least 38% alcohol by volume, and contain neither added alcohol nor flavorings. Caramel color is the only permitted additive.

 

Jerusalem artichoke brandy smells fruity and has a slight nutty-sweet flavor. An intense, pleasant, earthy note characterizes it. The tubers are washed and dried in an oven before being fermented and distilled. It can be further refined to make "Red Rossler" by adding the roots of the common tormentil, giving it a bitter and astringent taste and a red color. Red Rossler contains other ingredients such as currants, producing a schnapps with about 50% alcohol used as digestif and as a remedy for diarrhea or abdominal pain.

 

US marketing scheme

In the 1980s, the Jerusalem artichoke also gained some notoriety when its seeds were planted by Midwestern US farmers at the prodding of an agricultural attempt to save the family farm. This effort aimed to teach independent farmers to raise their own food, feed, and fuel. Little market existed for the tuber in that part of the US then, but contacts were made with sugar producers, oil and gas companies, and the fresh food market for markets to be developed. Fructose had not yet been established as a mainstay, nor was ethanol used as a main fuel additive as it is today. The only real profit in this effort was realized by a few first-year growers (who sold some of their seed to other farmers individually as well as with the help of the company attempting this venture). As a result, many of the farmers who had planted large quantities of the crop lost money.

 

Diseases and pests

Stem rot disease is caused by the fungus Agroathelia rolfsii (aka Sclerotium rolfsii or Athelia rolfsii), which is one of the most important pathogens causing tuber and stem rot and up to 60% loss in Jerusalem artichoke yield.[66] Growing resistant varieties is an important method of controlling Agroathelia rolfsii.

This is Sven who is just over a year old. I fenced in a rocky lot that I had to use a machete on to keep the weeds down.

I paired him up with Lil' Richard to see if having company inside an electric fence would convince the goat not to escape.

It worked but not until they played several games of 'Tag'.

Ring-necked Pheasant Habitat Focus Area

Ring-necked pheasant

Much of New York State's landscape no longer has the potential to produce wild ring-necked pheasants (Phasianus colchicus). Ring-necked pheasants are typically a product of agricultural lands that include small grains, fallow fields, and wetland areas that provide winter cover. The quantity of land in small grain agriculture is greatly diminished since the early 1900s, and the state is now mostly forested. Efforts such as the Breeding Bird Atlas and Spring and Summer Farmer Pheasant surveys indicate that New York's wild, self-sustaining pheasant population is largely restricted to the Great Lakes Plain in the western part of the state (see figure below). Because of this, efforts to protect, restore, and manage habitat for this species have the greatest chance of success if they are concentrated in this area.

 

Individually, DEC and its partners do not have the resources necessary to effectively manage for wild pheasants throughout the Lake Plains area. Therefore, we developed a focus area to concentrate current and future habitat management efforts. This will best utilize available resources to determine if maintaining or increasing wild pheasant populations is possible under current biological, social, and fiscal conditions. We feel that pooling resources, sharing information, and concentrating the efforts of government agencies, private organizations, and landowners is a more realistic and effective approach to sustaining a wild pheasant population in New York.

 

Using agricultural statistics, land use data, current information on pheasant distribution and abundance, and stakeholder input, we delineated a roughly 150,000-acre focus area in the Great Lakes Plain (see figure below). Based on the presence of wild pheasants and the composition of the agricultural landscape in this area, we feel that it has the greatest potential to maintain or increase wild pheasant numbers.

 

New York State Pheasant Habitat Focus Area

 

The goal of this effort is to sustain breeding populations of pheasants within the focus area. Our strategy is to: (1) work with our partners (e.g., USDA NRCS, FSA, Pheasants Forever) to provide information to landowners on ways to improve pheasant habitat and how best to use the funding available from government and non-government conservation programs to help implement some of those measures; (2) develop monitoring programs to measure the success of pheasant habitat improvements; and (3) develop guidelines for creation and enhancement of pheasant habitat and provide technical guidance (e.g., planting mixtures, mowing schedules) to promote interest among landowners to manage pheasant habitat within the focus area.

 

Monitoring Pheasant Populations

If you farm land in Livingston, Genesee, Wyoming, or Monroe counties, consider participating in the Farmer-Pheasant Inventory. If you do not farm, but you would like to contribute your pheasant observations, join the Summer Pheasant Sighting Survey (get survey form below).

 

Farmer-Pheasant Inventory

Farmers in the 13 counties that comprise the Lake Plains of New York have partnered with the department since 1945 to help survey wild pheasant populations. We are pleased to continue this effort in the Pheasant Habitat Focus Area in the Genesee Valley. Surveys like this one will help us monitor the response of pheasant populations to habitat management efforts. No special observations are required; just those made during your normal spring and summer farming activities.

 

If you are a farmer in Livingston, Genesee, Wyoming, or Monroe county and are interested in participating in the Spring Pheasant Inventory (April) or the Summer Pheasant Inventory (August), please contact us at (518) 402-8886, by e-mail, or by writing to "Farmer-Pheasant Inventory", NYSDEC, 625 Broadway, Albany, NY 12233-4754.

 

Summer Pheasant Sighting Survey

During the month of August, survey participants record the sex and age of all pheasants observed during normal travel in Livingston, Genesee, Wyoming, and Monroe counties. This survey will help estimate pheasant production (number of young per adult female pheasant), and over the long-term will help evaluate the success of habitat management efforts in the focus area.

 

If you would like to participate, you can print or download a Summer Pheasant Sighting Survey (PDF) (252 KB).

  

Completed surveys can be returned via mail (see address above) or e-mail (as a PDF attachment).

 

Habitat Conservation Assistance Program

If you are interested in learning more about this program, read the following summary or e-mail us:

 

Grasslands for Wildlife (GFW) - The goal of this DEC program is to establish grassland habitat demonstration areas within the Pheasant Habitat Focus Area. Activities include purchasing $10,000 of warm- and cool-season grass seed annually and distributing it to private landowners to establish grasslands; establishing grasslands 5-40 acres in size; forming partnerships with organizations interested in pheasants and other grassland wildlife; and increasing public awareness of the value of grasslands for pheasants and other grassland wildlife. Site selection is based on public access to the site, public viewing, length of contract (5 or 10 years), potential to increase pheasants, and proximity to other cover or food sources. The site must have at least a one-year history of weed control. Once the best sites are selected, the landowner works with DEC to create a maintenance plan and signs a cooperative agreement.

Minnamurra Rainforest Centre

Budderoo National Park

Jamberoo, NSW, Australia.

  

The Minnamurra Rainforest Area is found in the Budderoo N.P 15km west of Kiama & about 1hr south of Sydney.

It’s a 400 Hectare pocket of tropical & warm temperate rainforest.

The walk to Minnamurra Falls is approx. 4.2km return & the first 500m is wheelchair-friendly.

Allow about 2hrs for the walk to the falls - the top section is quite steep.

 

Boardwalks & raised platforms have been erected to minimise damage to the environment from the thousands of visitors the area receives every year.

Walkers are required to keep to the boardwalks so it does reduce the range of possible photography locations & compositions.

Photography of the river is difficult as the main vantage points are on swing-bridges & there is movement for a couple of minutes every time someone crosses them.

The Minnamurra Rainforest is beautiful but certainly not a wilderness experience due to the man-made infrastructure & constructions.

The lower section of the rainforest is quite pristine however there is still ongoing weed control & bush regeneration in the upper sections with lantana being an issue.

 

Minnamurra Falls consists of two levels, the upper falls which are 25m, and the lower falls which are 50m high.

Only the upper falls can be reached as rockslides have washed away the track that led to the lower falls.

The lower falls were originally the main attraction until the 1989 landslide & there is a an area of canyon there.

There is a lookout that gives you a vantage point to view the lower falls and a glimpse of the slot canyon.

Here’s hoping that one day the track is restored to provide access to an impressive & wild part of Minnamurra.

Bringing the weedkiller train sequence more up to date the days of pre nationalisation coaches converted to private owner departmental stock by the weedkiller companies to spray the weeds have long gone.

As part of the five year Network Rail haulage tender process what are known as "Treatment Trains" are offered out to the Railfreight sector to bid and cover the work using Network Rail owned MPV's (Multi Purpose Vehicles). These power twin or power+trailer units can carry various deck mounted options so prove very versatile their only draw back is the amount of product they can carry when it comes to spraying so they tend to operate single shift diagrams where the unit returns to a depot for crew change and replenishment.

When Motherwell TMD was owned by EWS there were several autumn railhead treatment trains usng MPV's but during the summer months one unit sufficed for weed control operations.

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".

Canna indica, commonly known as Indian shot, African arrowroot, edible canna, purple arrowroot, Sierra Leone arrowroot, is a plant species in the family Cannaceae. It is native to much of South America, Central America, the West Indies, and Mexico. It is also naturalized in the southeastern United States (Florida, Texas, Louisiana, and South Carolina), and much of Europe, sub-Saharan Africa, Southeast Asia, and Oceania.

 

It (achira in Hispanic America, cana-da-índia in Brazil) has been a minor food crop cultivated by indigenous peoples of the Americas for thousands of years.

 

Canna indica is a perennial growing to between 0.5 and 2.5 metres (1+1⁄2 and 8 feet), depending on the variety. It is hardy to zone 10 and is frost tender.

 

It forms branched rhizomes 60 centimetres (24 inches) long that are divided into bulbous segments and covered in two lines by pale green or purple flaky leaves. The very large grains of starch stored there can supposedly be seen with the naked eye. The plants form an upright, unbranched stem or the overlapping leaf sheaths form a pseudo trunk.

 

The alternate and spiral or two-line arranged, very large, simple leaves are divided into leaf sheaths, short petioles and leaf blades. The leaf blade has a length of 30 to 60 cm (12 to 24 in) and a width of 10 to 20 cm (4 to 8 in). The parallel leaf veins arise from the midrib (not typical of monocots). The leaves are broad, green or violet green, with elliptical sheets, which can measure 30 to 60 cm long and 10 to 25 cm wide, with the base obtuse or narrowly cuneate and the apex is shortly acuminate or sharp. The surface of the rhizome is carved by transverse grooves, which mark the base of scales that cover it; from the lower part white and apex rootlets emerge, where there are numerous buds, the leaves sprout, the floral stem and the stems.

 

The flowers are hermaphrodite. The mostly large flowers are zygomorphic and threefold. On pedicels, they are 0.2–1 cm (1⁄8–3⁄8 in) long, red or yellow-orange, except in some cultivars, 4.5–7.5 cm (2–3 in) long, with the sepals being closely triangular, 1–1.7 cm (1⁄2–3⁄4 in) long and the petals erect, 4–6.5 cm long. The tube is 1.5–2 cm long. 

 

The bracts are designed differently. The three free sepals are usually green. The three petals are green or have depending on the variety shades of yellow about orange and red to pink. The base of the petals is fused with the staminodien to a stamen column. There are two circles, each with originally three stamens present. The petals and staminodes are usually yellow to red. The three carpels are at a constant under (syncarp) ovary adherent which has a soft-spiky surface and many central-angle-constant ovules. The pollen is deposited on the abaxial (off-axis) surface of the stylus.

 

The pollination mechanism is very specialised and the pollination is done by insects. The insects pick up the pollen from the flattened style. In their natural habitat, blooming occurs in the months of August to October. The fruits are ellipsoid capsules to globose, warty, 1.5 to 3 cm long, chestnut coloured, with a large amount of black and very hard seeds.[

 

The seeds are small, globular, black pellets, hard and dense enough to sink in water. They resemble shotgun pellets giving rise to the plant's common name of Indian shot. The seeds are hard enough to shoot through wood and still survive and later germinate. According to the BBC, "The story goes that during the Indian Mutiny of the 19th century, soldiers used the seeds of a Canna indica when they ran out of bullets."

In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. Maas regards C. coccinea, C. compacta, C. discolor, C. patens and C. speciosa as synonyms or varieties of C. indica, while Tanaka recognises several additional varieties of C. indica.

 

A medium sized species; green foliage, oblong shaped, spreading habit; triangular flower stems, coloured green; spikes of flowers are erect, self-coloured red, staminodes are long and narrow, edges regular, petals red, partial self-cleaning; fertile both ways, self-pollinating and also true to type, capsules globose; rhizomes are thick, up to 3 cm in diameter, coloured purple; tillering is prolific. Introduced by Linnaeus.

Canna indica var. flava (Roscoe ex Baker) Nb. Tanaka

Yellow bloom. Many plants previously offered as C. lutea fall into this subspecies.

Canna indica var. maculata (Hook) Nb. Tanaka

A medium sized species; green foliage, ovoid shaped, branching habit; spikes of flowers are erect, yellow with red spots, staminodes are long and narrow, edges regular, petals green, fully self-cleaning, low bloomer; fertile both ways, self-pollinating and also true to type, capsules globose; rhizomes are thick, up to 3 cm in diameter, coloured white and pink; tillering is average. Introduced by Hook.. Many plants previously offered as C. lutea fall into this subspecies.

Canna indica var. sanctae rosea (Kraenzl) Nb. Tanaka

A small species; green foliage, oval shaped, white margin, branching habit; spikes of flowers are erect, self-coloured pink, staminodes are long and narrow, edges regular, labellum is pink, stamen is pink, style is pink, petals red with farina, fully self-cleaning; fertile both ways, self-pollinating and also true to type, capsules ellipsoid; rhizomes are thick, up to 3 cm in diameter, coloured white and pink; tillering is prolific.

Canna indica var. warszewiczii (A.Dietr.) Nb.Tanaka

This variety is distinguishable from C. indica var. indica by having purple-red-margined leaves, purple-red fruits and slightly corm-like thickened terrestrial stem at the base. Additionally to this, there are normally two staminodes, recurved backwards, and the stamen is often strongly reflexed at the apex. These characteristics are fairly stable in this taxon. Sometimes, this variety is confused with C. discolor Lindl., from which it differs in much smaller, deep-red coloured flowers, short and slender rhizomes and chromosome numbers (2n=27 in C. discolor and 2n=18 in C. indica var. warszewiczii)

John Gilbert Baker recognizes 2 varieties: Canna indica var. napalensis (Wall. ex Bouché) and Canna indica var. orientalis (Roscoe), William Aiton recognizes 2 varieties of Canna indica var. lutea (Mill.) and Canna indica var. rubra, and Eduard August von Regel recognizes one variety of Canna indica var. edwardsii.

 

Canna indica is native to South America: Colombia, Venezuela, Ecuador, Peru, Brazil, Uruguay and Argentina as well as the West Indies and Central America.

 

In modern times, C. indica is reportedly naturalized in Austria, Portugal, Spain, Azores, Canary Islands, Cape Verde, Madeira, most of tropical Africa, Ascension Island, St. Helena, Madagascar, China, Japan, Taiwan, the Bonin Islands, India, Nepal, Sri Lanka, Cambodia, Laos, Thailand, Vietnam, Burma, Java, Malaysia, the Philippines, Christmas Island, the Bismarck Archipelago, Norfolk Island, New South Wales, Queensland, Fiji, Tonga, Vanuatu, Kiribati, the Cook Islands, the Society Islands, the Caroline Islands and Hawaii.

 

Canna can be cultivated from sea level to 2,700 m (8,900 ft) above sea level, but thrives in temperate, tropical or subtropical mountain climates, between 1,000 and 2,000 m (3,300 and 6,600 ft) above sea level (in humid tropical climates for higher elevations) at a mean temperature of 14 to 27 °C. The plant prefers a mean annual rainfall between 1,000–4,500 millimetres (3+1⁄2–15 ft), but it can tolerate 500–5,000 mm per year. Canna prefers light sandy-loamy soils, but can also grow on heavy soils, as far as they are not wet. It is indifferent to soil pH. For seeds to germinate, they must soak in water for two to three days.

 

Cannas suffer from relatively few diseases compared to other species. Nevertheless, some diseases have been recorded to affect C. indica. One of them is Canna rust (Puccinia thaliae), a fungus that causes orange spots on the leaves. In addition, plant viruses occur: Hippeastrum mosaic virus, Tomato aspermy virus, Canna yellow mottle virus and Canna yellow streak virus which can cause mild or strong symptoms from streaked leaves, stunted growth to distorted blooms. Furthermore, there is Botrytis (fungus), a mold that affects the flowers.

 

Many different Canna varieties exist, and some of them are resistant to a certain type of disease. To prevent mold, the soil should be well-drained without too much soil moisture or stagnating water. To diminish the risk of spreading diseases, dead and infected leaves should be removed.

 

The canna leaf roller butterfly (Calpodes ethlius) has been seen on Canna plants in the US. It is a caterpillar known as the worst pest for this plant and primarily found in the Southern United States. This pest causes damages by laying its eggs in the bud of developing stalks. To protect the eggs from predators and insecticide, caterpillars use sticky webs to keep the leaves from unfurling. The pupate then feed on the leaves which can lead to losses of yield due to reduced photosynthesis.

 

The Japanese beetle (Popillia japonica) is another leaf ragging pest with mainly small consequences for Canna plants. This beetle feeds on the part of the leaves between the veins. In its originating region in Japan, it does not cause a lot of damages. However, in the US it has no natural predator and can cause serious damages on Cannas and other plants.

 

The bird cherry-oat aphid (Rhopalosiphum padi) has been recorded to affect stored rhizomes. Although this pest has not been causing severe damages yet, it can particularly affect plants grown in greenhouses and can be combatted with parasitical wasps. It is a more common pest on cereals.

 

C. indica has been included in the Global Invasive Species Database and has been declared as invasive in the following places:

 

South Africa where it is categorised as a category 1b Invader in terms of the National Environmental Management: Biodiversity Act (10/2004) list of Alien and Invasive Species which prohibits their cultivation, propagation, translocation and trade, and requires them to be removed and destroyed when found. This is because it competes with and replaces indigenous species, often in waterways and marshy areas.

Australia, regarded as a weed in New South Wales and South Eastern Queensland

Pacific Islands, where it has been included in the list of plant threats to Pacific ecosystems as a high-risk species

Tanzania, where although it was included in a list of 41 'problem' plants in the Serengeti-Mara ecosystem, it has been assessed to be naturalised in tourist areas, but not invasive (using roadside surveys)

Ghana, where it was noted to compete with and invade natural shrub and tree woodland vegetation in the Boabeng-Fiema Monkey Sanctuary and Kakum National Park

Cultivation

 

Canna indica (achira) has been cultivated by indigenous peoples of the Americas in tropical America for thousands of years. The place of the first domestication may have been the northern Andes, as may be true of other similar root crops such as Calathea allouia and M. arundinacea. The Cauca river valley of Colombia was a center of early domestication. Archaeological evidence has been found of the cultivation of achira in 3000 BCE by people of the Las Vegas culture of coastal Ecuador. As the Las Vegas region is arid and semiarid, achira was not likely a native plant, but imported from more humid climates. Achira was also being cultivated by 2000 BCE by the people of the Casma/Sechin culture in the extremely arid region of coastal Peru, also an area in which achira was probably not native.

 

To cultivate Canna indica, the substrate should be rich, humiferous, and light. The optimal substrate consists of a deep, rich and well-drained soil in a sunny place with a pH between 5.5 and 7.5. The rhizomes should be planted at 10 cm deep, after the last frost. Although it can tolerate dry periods, occasional irrigation will be beneficial for the yield. C. indica is a plant that can withstand low temperatures (down to -10 °C in regions with a mild climate). Nevertheless, the foliage can already be affected at 0 °C.

 

Canna indica is usually propagated by putting either the rhizome tips or the whole rhizomes in the ground. Because the rhizomes are quickly perishable, storing them properly between the harvest and the next planting time is essential. The large rhizomes can be divided in spring before the new shoots appear. Additionally, Canna indica can also be propagated by seeds. Seedlings growing early in spring are able to flower the same year they are sown.

 

The amount of rhizomes used for sowing is normally about 3,000–4,500 kg/ha, and the planting density should not exceed 22,500 plants/ha. When putting the rhizomes in the ground, the sprouts should point upwards. The ideal spacing between plants in a row is 60–70 cm, and the spacing between rows is 70–80 cm. Because Canna indica grows quite tall, it should be cultivated at locations with relatively low wind speed to prevent bending over. Germination begins when the soil temperature is above 16 °C, while the optimal temperature is 20–25 °C. 20–30 days after sowing, seedlings emerge.

 

Canna indica is reliant on fertilizer to achieve a good yield. In the early stages, seedling fertilizer should be applied during the first tillage and spread according to seedling conditions. Up to 750 kg/ha of ternary compound fertilizer (N, P, K) can be applied. When applying fertilizer, direct contact with the base and leaves should be avoided. Before flowering, the second tillage can be combined with the second fertilizer application to promote the growth of underground stems and roots. Applying fertilizer evenly on both sides of the roots helps them to absorb water and grow uniformly.

 

Fast growing weeds can have a negative impact on C. indica, especially before the fourth leaf appears. Two weed control methods are usually practiced: firstly, applying herbicides to eradicate weeds and secondly, carrying out mechanical operations depending on the weed growth.

 

About six months after planting, the crop can be harvested. At this time, the rhizomes are tender and succulent. However, the rhizomes are mainly harvested later, after 8–10 months, when they reach their maximum size. C. indica is suitable as an emergency crop in case of shortfalls due to its long durability in the ground. It can be harvested during times when the cultivation of other crops is not successful.

 

Harvesting is done manually by pulling out the crop with a shovel or another digging tool, shaking off the soil, and then cutting the stems to separate the rhizomes.

 

The yield varies depending on the region of cultivation and its climate and soil conditions. In certain locations, the yield of Canna indica can be higher than other starchy crops like cassava and arrowroot. The average rhizome yield is believed to be around 22–50 tons per hectare, whereas the starch yield is about 2–5 tons per hectare and can reach up to 10 tons per ha. Observations show that the highest yield in rhizomes does not necessarily correspond to the highest yield in starch.

 

Rhizomes for starch extraction should be processed within days after the harvest due to their perishability. The following steps of traditional starch production in Colombia show that the process is dependent on a significant supply of fresh water.

 

In rural areas in Colombia, the recently harvested rhizomes are packed up in sacks and transported to the processing site. The first step is cleaning the rhizomes by washing them in tanks. The second step is grating the rhizomes mechanically to disrupt the cell walls to release the starch. The third step is sieving to separate the starch from the rest of the rhizome pulp: The grated rhizomes and additional water are passed manually or mechanically through a sieve. The fourth step is separating the starch from the sieving water by letting the starch granules sink to the bottom of a tank. The fifth step is washing the starch multiple times with clean water. The last step is drying the starch by exposing it to the sun. The starch is now ready to be stored or transported.

 

Canna indica sps. can be used for the treatment of industrial waste waters through constructed wetlands. It is effective for the removal of high organic load, colour and chlorinated organic compounds from paper mill wastewater.

 

The seeds are widely used for jewellery. The seeds are also used as the mobile elements of the kayamb, a musical instrument from Réunion, as well as the hosho, a gourd rattle from Zimbabwe, where the seeds are known as "hota" seeds.

 

The starch is easily digestible and therefore well suited as a health and baby food. The tubers can be eaten raw or cooked. The starch is also suitable for baking. In South America, the leaves are used to wrap pastries (tamales, humitas, quimbolitos, juanes, etc.), similar to banana leaves or maize leaves. In some areas, the leaves are fed to livestock. The round seeds are pierced in some areas and used as pearls. They are also used as a filling of rattles. From the Indians, the seeds were previously used as gold weights, similar to the seeds of carob (Ceratonia siliqua), as they have a constant weight.

 

The large rhizomes are edible. They can be eaten raw, but are usually baked. Cooked, the rhizomes become translucent, mucilaginous, and sweet. Starch is produced by grinding or pounding the roots and soaking them in water, separating the starch granules from fibers in the roots. The starch granules of C. indica are also translucent and the largest known from any plant. The starch is occasionally marketed commercially as "arrowroot", a name also applied to the starch of other similar roots crops such as Maranta arundinacea. It was an ingredient in mid-nineteenth century recipes such as cakes and was called tous-les-mois.

 

The Spanish took notice of achira in 1549 when it was mentioned as one of four root crops being grown for food by the people of the Chuquimayo valley (Jaén province) of Peru. The other three were sweet potato (Ipomoea batatas), cassava (Manihot esculenta), and racacha (Arracacia xanthorrhiza). In 1609, achira was described by a Spanish visitor to Cusco, Peru. In modern times, achira is rarely grown for food, although in the 1960s it was still an important crop in Paruro Province on the upper Apurimac River near Cusco. There, at elevations of up to 2,600 metres (8,500 ft), achira is cultivated and harvested, especially to be eaten during the Festival of Corpus Christi in May or June. The achira rhizomes are wrapped with achira leaves and placed in a pit with heated rocks. The pit is then filled with dirt and the achira is slowly baked underground.

 

In the 1950s, Canna indica was introduced to China as a perennial ornamental crop. It was mainly planted in parks and home gardens in Guizhou for ornamental purposes. From the late 1950s to the early 1960s, China suffered from a severe food shortage, known as the Great Chinese Famine. During this time, weeds, tree roots, tubers, etc., became an important food source. Canna indica was also part of this famine food. As a consequence, the plant became known as a food crop. Today, the rhizomes are processed to starch, vermicelli, white wine, and ethanol. Due to the use as a food crop and relatively low diseases and pests pressure, Canna indica has become a characteristic crop for large-scale cultivation in China. The research in China mainly focuses on processing methods, and additionally, there are few studies on varieties and cultivation techniques.

 

The Achira rhizomes consist of 73% water. In addition to 24% starch, they still contain 1% protein, 0.6% crude fiber and 1.4% minerals.

 

In China, Canna indica starch and polyethylene are used as raw materials to produce biodegradable plastics. This type of plastics is affordable and can degrade completely into fertilizer for crop production in just a few months. The method for producing C. indica plastics consists of fusing 60–80% of C. indica starch and 20–40% of polyethylene uniformly at 240 °C.

I drove past this field yesterday in the blazing sunshine and as the sun reflected off of the plastic strips it was really striking. I wanted to get a photo then but it was hard to pull over.

 

I decided to drive back out early this morning in the hope there would be some mist. It had been raining in the night and a slight mist added to the beautiful dawn glow.As the sun shone through the mist it created an amazing halo effect. I took about 10 shots and as I had finished the mist had already gone.

 

Good timing.

 

Incidentally, the field is covered in lines of plastic. I'm guessing this is some kind of weed control, but if anyone knows the name of the process or more details please post below. Thanks

That colorful splendor outside does not require any extra effort from bee colonies for pollination. However, quite a bit of human work is required. A major bottleneck is weed control. This can partly be solved with herbicides, but hoeing and weeding are also necessary. Together with harvesting (cutting, putting on horsemen to dry and then threshing) that is a lot of manual work, so very heavy. Incidentally, drying also takes place in drying rooms at contractors.

I thought this train (U-NSMTND) got parked in La Crosse but when I received word that he was passed Trevino, I bolted out the door. I made it to Prescott in plenty of time as evidenced by the shot. These units are slowly being rebuilt into AC44C6M's and losing their standard cab so now is the time to shoot them. C Vision Productions even made an appearence here. It would be appreciated if BNSF did some weed control here. If not, I would gladly do it for them.

Flowers on a kakabeak shrub (Clianthus maximus), an endemic New Zealand legume. This specimen has been cultivated from one of the exceptionally rare wild plants growing in Maungataniwha Forest, northern Hawke's Bay.

 

Kakabeak is at a very serious risk of extinction. Their red flowers resemble the beak of the kākā, an endemic New Zealand forest parrot. Only 153 mature plants are known from the wild, all occurring in remote parts of eastern North Island where they are threatened by introduced browsing animals (goats, deer, rabbits, and hares), diseases, and natural senescence. Many populations are also threatened by fire, weed control operations, natural succession, and the unstable, erosion prone nature of the habitats in which they remain.

 

Native honeyeaters (tui and bellbird) love to drink from the flowers. Although the species is widely grown as a garden plant in New Zealand, the cultivated lines are descended from only a few plants and therefore lack genetic diversity. This specimen was cultivated by members of the Forest Lifeforce Restoration Trust from seed collected from a wild plant in Hawke's Bay's remote Waiau River valley, Maungataniwha Forest. This gives it genetics different to most cultivated specimens. We were lucky enough to be given a few specimens whilst staying in the area for a geological field trip, looking for dinosaur fossils in the area. It's a colourful reminder of a great field trip to a lovely and remote part of New Zealand.

CAPTION: "The food sovereignty movement has gained significant momentum throughout the country in recent years and is largely being led by indigenous communities."

 

NRCS ARTICLE 4/2020: There’s a sense of pride that comes with doing something for yourself, and growing food is a major part of being self-sustaining, healthy and whole.

 

A one-acre community garden on the Rosebud Indian Reservation in south-central South Dakota is connecting tribal members with the land, with food, and with their past.

 

“It’s about food sovereignty. It’s about having the choice of where and how you get your food, knowing how to feed yourself,” said Matte Wilson. “If that grocery store wasn’t here, would you know how to feed yourself and your family?”

 

Born and raised on the Rosebud Indian Reservation, Wilson is now director of the recently re-branded Sicangu Community Development Corporation (CDC) Food Sovereignty Initiative. One of its major projects is the Keya Wakpala Garden. Since moving back home in 2018, food sovereignty has played a major part of Wilson’s life.

 

“It is something that really excites me, something I could see myself doing for the rest of my life,” he said.

 

Vegetable Harvest on table

The food sovereignty movement has gained significant momentum throughout the country in recent years and is largely being led by indigenous communities. According to Wilson, you don’t have to be indigenous to appreciate delicious, locally grown foods.

 

“Food has the power to bring people together – it’s always been an essential part of all of our social interactions, whether or not you are Lakota,” he said.

 

For Keya Wakpala garden manager Ed Her Many Horses, the garden and learning how to grow food has been nothing short of trans formative.

 

“It’s impacted me in a lot of different ways,” he said. “It helped give me a reason to get up in the morning – it still does. There is so much to appreciate in the garden.”

 

But it’s more than food, he’s found. Caring for a garden fosters community. The Keya Wakpala Garden is a place where interns, volunteers, community members and children come together to work, and they take pride in the outcome.

 

“It’s a beacon of hope, I think,” Her Many Horses said.

The Boys and Girls Club brings kids to the garden where they can plant, pick vegetables and even harvest indigenous foods such as ceyaka, wild mint, in the nearby wetlands. They learn to identify foods as they’re grown and harvested, and follow up field work with cooking sessions. Starting with young kids, the project aims to make gardening and producing food something that’s second nature – something they’re able to pass on to future generations.

 

Learning by doing is key, according to Wilson.

 

“When they are able to see it in person and participate in the process, it is really powerful. It makes people appreciate food and agriculture more,” he said.

 

Foster Cournoyer-Hogan is a student at Stanford University from the Rosebud Indian Reservation who interned for the summer at the Keya Wakpala Garden. His additions to the garden plot included the signs that identified the plants with Lakota words. There was wagmu (squash), tinpsilazizi (carrots), phangi sasa (beets) and mastincatawote (lettuce).

 

Using the Lakota language is a way to stay connected to traditional culture. That’s especially important when children and elders visit the garden, he said.

 

Along with strengthening connections to culture and community, the garden is helping solve another issue on the reservation – addressing health challenges. Diabetes and diet related illness is high on the Rosebud Indian Reservation, but the produce from the garden gives people access to nourishing food.

 

“Our food is everything,” Cournoyer-Hogan said.

 

“Food is medicine,” added Wilson: “The way we treat our garden, the way we treat the land is how we treat ourselves … we take care of the land, and it takes care of us.”

 

The group has some expert resources when it comes to taking care of the land and the plants. Master Gardeners and university extension experts have volunteered their time and advice, and the Natural Resources Conservation Service (NRCS) provides support and funding through soil health programs.

 

The mission of NRCS is “helping people help the land.” That land usually refers to range land and farm acres, but the same programs and principles can apply to community gardens.

 

“We're trying to get people together to go back to some of the things that were important years ago to our people for self-sustainability,” said Mary Scott, a Rosebud Indian Reservation member and tribal liaison with NRCS.

The reservation’s growing environment presents some significant challenges. The garden site had been a conventional field, growing sunflowers, corn, soybeans and wheat. The heavy clay soils made it difficult to hold enough water for the garden, especially given the sloping hillside where it sits. Long, hot days would burn up the plants one day, and they next they’d be hit by torrential downpours, hail and wind.

 

“There are a lot of things outside of our control,” said Her Many Horses, “and that can be tough in such an extreme weather environment”

 

Rather than give up, however, the team has simply learned to adapt and make the most of what they have.

 

“We have to be really strategic about how we plan out our year to make the most of this short window,” Wilson said. “We have branched into utilizing some year-round growing structures to expand our season.”

 

The garden is tended with organic methods, using fish emulsion and compost for fertilizer. Local ranchers have donated hay bales – the more beaten-up and weather-worn the better. As ground cover, they help with weed control. Adding mulch or organic matter has helped break up the hard, clay soil and has been a huge asset for moisture retention as well.

 

We’re using a regenerative approach to agriculture,” said Her Many Horses. “We’re always trying to give back to our soil.

The garden also incorporates time-honored growing techniques of the tribal community. Produce is grown with the three sister’s method – beans, corn and squash grow in rows and benefit from one another.

 

“Beans help fertilize the soil by providing nitrogen,” Wilson explained. “The corn, when it grows up the stalk, the beans are able to wrap around the stalk, and the squash actually helps keep out pests and other weeds.”

 

7 workers talking in the garden

It’s one of many ways the garden is bringing the community back to its roots. It also brings youth and elders together, sharing a positive outlook while producing something for the whole community. It connects people with land and community, giving them knowledge to pass along wherever they go.

 

Sharing knowledge is a big part of the project, Scott said, because it’s how cultures and traditions are kept alive.

 

“Growing our own produce is very important, so that this community can become self-sustaining, not only as a people, but as a tribe,” she said.

 

The ultimate goal is to completely change the food system on the Rosebud Indian Reservation.

 

“My vision is that our community becomes a food center where we have restaurants and food trucks sourcing their foods locally,” Wilson said, “and the garden is the first step to helping change our community mindset about food.”

 

But it goes even deeper than that.

 

“I hope that our community can be healthy and happy, that we can be sovereign,” said Her Many Horses. “And for us, that starts with everyone knowing where their food comes from.”

NIR's somewhat home-made weed control train passes through Ballinderry on the Antrim - Knockmore line. For some reason now forgotten, the CIÉ sprayer was unavailable in 1975 (or NIR had no money to hire it) and this contraption was cobbled together, probably at York Road, in order to keep the weeds down!

 

As far as I am aware, 1975 was its only year of use.

BISA is a non-profit research institute dedicated to the improvement of food security and reduction of hunger in South Asia. It is a collaborative effort between the International Maize and Wheat Improvement Center (CIMMYT), The Indian Council for Agricultural Research (ICAR), and the Government of India. BISA’s objective is to harness the latest technology in agriculture to improve farming productivity and sustainably meet the demands of the future. More than just a bricks-and-mortar institute, BISA is a commitment to the people of India. It is co-located in three Indian states—Punjab, Bihar, and Madhya Pradesh—each of which contains varied agro-ecological zones, representing many of the environments of South Asia.

 

In Bihar, the current major constraints to maize production are low seed replacement rates, late sowing, and low levels of farm mechanization. Foliar blight disease is also a growing concern among Bihar’s farmers. Both hybrids and traditional maize varieties are grown throughout Bihar and maize productivity is currently 2.5 tons per hectare, higher than the national average of 1.9.

 

Areas of future development for BISA Pusa include the development of climate-resilient cultivars, innovative maize genotypes, diverse wheat cultivars, disease resistance, farmer information technologies, and new irrigation technologies. Initial trials have indicated that the implementation of zero tillage on 1.5 million hectares has the potential to increase soil moisture and enhance wheat production by 0.45 million tons. The promotion of quality protein maize to address malnutrition rates as well as long-term conservation agricultural trials is also a priority for the site.

SF Bay RR, 21 June 2018

 

The San Francisco Bay RR operates on the southeast side of San Francisco on and near the port. It uses two Alco S2 switchers that were built for the State Belt RR, later the San Francisco Belt RR, the line that served the piers of the Port of San Francisco for many years.

 

As shipping companies moved to containerization, the Port of Oakland became the big northern California container terminal and most of the piers of the Port of San Francisco were abandoned or converted to uses other than marine freight, so the SF Belt RR found itself out of a job. After 1989 Loma Prieta earthquake damaged the Embarcadero Freeway, which had run over the SF Belt for most of its length, the freeway was removed, opening up San Francisco's waterfront and much of the Belt's trackage as converted for use by the Muni F line, which runs historic streetcars to Fishermen's Wharf, and the Muni lines that now server the Caltrain station.

 

Meanwhile, Pier 96, near Hunter's Point was converted to a container facility and the railroad's operations survived there. The line was renamed the San Francisco Bay RR and continued to use Alco S2s 23 and 25 to switch its customers.

 

Today, the railroad's main business is transloading dirty dirt from constructions and clean up sites in the Bay Area from trucks to railcars. It is owned by Waste Solutions Group, which also owns a fleet of hopper cars. The SF Bay and UP interchange on an as needed basis, with UP's South City job running into the SF Bay's yard on Cargo Way with empties and taking away loads.

 

A couple of railfans, Ryan and Ben, work for the railroad and Ryan invited me to come by for a visit. I had stopped by one afternoon a couple of years ago, and lucked out to see an S2 running around the yard a bit, but the railrroad usually goes on duty betweeen 4 and 5 am, switches cars for a few hours and then is done for the day. So, a visit to the SF Bay from Sacramento entailed a night in a hotel. It took a few tries for me to get time off from work scheduled on the same day the railroad was running.

 

Eventually, it all lined up and my alarm went off at 0315 at a hotel in Daly City, just south of the SF city limit.

 

I was at the yard by 4 and met Ben, who went out and started Alco 23. 25 is out of service with a bad bearing on the radiator fan drive shaft. Ryan explained that the SF Belt had done a jerry rigged repair of the shaft at some point and it was never documented, so nobody knew about the bearing until it failed. As a new low emission unit will be delivered in the next few months, there is no reason to repair 25. 25 will be put on display somewhere, perhaps near the Ferry Building, while 23 will be held as backup for the new unit.

 

But for now, an S2 built in 1944 is doing the job it was built to do. If you think about it, that is as though the Virginia and Truckee had still been using the Reno and Genoa during WW2.

 

Shorty after I got there, Ben went out and fired up the 23. It has a block heater, so it started easily with a puff of white smoke. He did an inspection of the engine, including checking the journal boxes. We then went back into the office and waited for Ryan, brakeman Johnny, and engineer Nick to arrive. The crew plotted their switching moves for the day. Ryan, who is yard operations manager, suggested that I get some blue hour photos from the ground as empties were switched and then we rode 23 while they switched loads.

 

Each car has dirt from one particular construction site and the dirt from sites cannot be mixed as different sites will have different contamination. UP ships it to a dump site in Nevada, where it is processed. Ryan explained that sometimes they can use dividers in a car to separate dirt from different projects if there is not that much.

 

Right now transshipping dirty dirt is the SF Bay's only business, but there a couple of other industries are interested in bringing new business. The line that crosses the Illinois St. bridge has been out of service for a couple of years as there currently no customers north of Islais Creek.

 

We rode the S2 for a while after the day brightened, then got down and Ryan drove me around in a company car to get some more angles as they switched. He then had other work to do and I shot the end of 23's work day as well as 25, some spare Alco parts and another project of Waste Solutions, goats that are leased out for natural weed control. Ryan said that since Waste Solutions got more cars, they can't use their goats as much for weed control in the yard as most of the yard tracks are occupied.

 

The crew called it a day for switching about 0800 and then would be doing other work in the yard for the rest of their work day.

 

All of these photos were taken with permission after signing a release and while wearing required PPE.

 

I want to than Ryan, Ben, Johnny and Nick for their hospitality. I had a great time.

The driver is looking-back to see if he still has a train as 101 "Eagle" heads out of Portadown, taking the weed control train back to Dundalk.

 

Chasing it on could have been difficult, given the state of the road in 1989. Besides, it was probably late and I may have fancied lunch in "The Bodega", or coffee and a snack in the little cafe in the shopping centre (which did a mean fruit scone, but is probably long gone). Was this the last time all three 101s worked on the same day? Only time will tell during this wander through the collection.

Photographed in the Eden Valley, South Australia (75 km north-east of Adelaide, one valley over from the better known Barossa Valley)

 

The most famous vineyard in Australia - indeed, in the southern hemisphere - is undoubtedly Hill of Grace, owned by the Henschke family for more than a century. The wines from this vineyard, the first portion of which was planted in the 1860s, are some of the most expensive in the world - about $600 a bottle on release. Helen and I are lucky to have a few precious bottles in our cellar, dating back to the 1986 vintage.

 

Wine-lovers from around the world regularly make a pilgrimage to see this great piece of property. We first visited proprietor Stephen Henschke in 1989, and we returned for a visit in November 2014. In September 2015 we had dinner with the Henschkes in the Barossa Valley.

 

From the Henschke web site:

 

"Hill of Grace is surely one of the most evocative phrases in the world of wine. It is a translation from the German ‘Gnadenberg’, a region in Silesia, and the name given to the lovely Lutheran Church across the road. For Henschke, it is the name of both the vineyard and the wine that has so beguiled lovers of red wine. The 8ha single vineyard on the original 32ha block sits at an altitude of 400m and has an average rainfall of 520mm. It is situated near the family property at Parrot Hill, an isolated spot that was once an active village.

 

The land was originally granted to Charles Flaxman by land grant in 1842 for £1 per acre. It was then sold by George Fife Angas to Nicolaus Stanitzki in 1873, for £480. Following his death the property was transferred in 1879 to his son Carl August Stanitzki, who later sold the vineyard and moved from the district. Paul Gotthard Henschke purchased the vineyard in 1891. After his death, his sons and executors Paul Alfred and Julius Philip Henschke arranged the transfer to Julius Philip, who had married Ida Maria Magdalena Stanitzki, a granddaughter of Nicolaus Stanitzki. On Julius Philip’s death in 1928, the property transferred to his wife. In 1951 the property was purchased by Louis Edmund Henschke, a son of Paul Alfred Henschke and brother of Cyril, who worked the vineyard and property for nearly 40 years. The Henschke family continue to maintain the tradition and develop new ways of preserving the precious genetic heritage for future generations.

 

As with the winery, each generation has added to the vineyard, which is now home to eight blocks of shiraz of various ages, as well as semillon, riesling and mataro (mourvèdre). The whites are used in Eden Valley varietals while the mataro, with its rich colour and complex flavour, often complements blends such as Henry’s Seven.

 

The Grandfathers, as the oldest block is called, was planted by Nicolaus Stanitzki around the 1860s. These vines are planted on their own roots from pre-phylloxera material brought from Europe by the early settlers. The sturdy, gnarled vines are dry grown and yield an average of 2.5t/ha (1t/acre). The shiraz vines are planted on a wide spacing of 3.1m between vines and 3.4m between rows. The 1m trellis consists of two wires which carry two or three arched canes with a bud number of around 40 to 50. The foliage is allowed to hang down to form a drooping canopy, which helps to reduce shoot vigour. The more vigorous blocks have been converted to VSP (Vertical Shoot Positioning) and Scott Henry to open up the canopy.

 

The mataro is grown as bush vines, which suits the upright growth of this variety. The whites are planted closer together than the reds, down to 2.2m, and have the regular 3.4m between rows to suit the old tractor widths.

 

Originally the ground was cultivated and the vines were ‘dodged off’ in spring and ‘hilled on’ again in early summer for weed control. Nowadays, under the guidance of viticulturist Prue Henschke, the vineyard has a permanent sod culture of early-maturing perennial rye grass in the row, which is mowed down low. The vines are no longer dodged and a mulch of wheat straw is used under the vines to retain soil moisture, build up organic matter, and inhibit weed growth. Prediction of disease pressure through an integrated pest management program is a strong part of Henschke’s viticultural management, resulting in minimal chemical input in the vineyard. The vineyard is currently run incorporating organic and biodynamic practices. Yield estimates are carried out in early summer, and cropping levels are kept in check by bunch thinning at veraison. The grapes are picked early to mid-April at a sugar level of around 24°Bé. There is always a good acid/pH balance from this vineyard. The anthocyanins (colour pigments) in the berries are also very high, which perhaps offers a clue to the very high quality of the Hill of Grace shiraz.

 

While much work is being done in the vineyard with biodynamics and organincs, Prue is also focused on protecting the vines for future generations, and in 1986 began a clonal selection program to identify the best vines to propagate, and where else to look but to the Grandfathers block which she has often referred to as old soldiers.

 

Prue and her assistant Uschi (Ursula Linssen), who had studied together at Geisenheim, literally walked the rows together, earmarking potential vines. They took a scientific approach, using criteria such as even budburst and the absence of Eutypa, a wood-rotting fungus that wasn’t the problem they had imagined. Then they moved through to flowering to look at bunch numbers per shoot, the evenness of flowering and veraison, virus, and finally the fruit itself. What was the bunch composition and bunch structure? How was the balance of sugar, pH and acid? And all this was after they had already eliminated vines they didn’t deem suitable. It was painstaking work, slotted in with the Mount Edelstone selection and the first of four selections planned extending over at least a 20-year program."

Gardening in Raised beds, a common practice before colonial times, is enjoying a resurgence of popularity among home vegetable growers. In parts of the world with greater population densities or less tillable land, gardening in raised beds is still the norm.

"Raised" means that the soil level in the bed is higher than the surrounding soil, and "bed" implies a size small enough to work without actually stepping onto the area used. A bed should be no wider than 4 feet, but length can be whatever suits the site or gardener's needs. Wider beds can be subdivided into sections accessible from wooden grids. The raised gardening bed does not have to be enclosed or framed. The use of power tillers is feasible, for example, in unframed beds, although a properly maintained bed should not need power-cultivation.

Higher Yields:

There are many reasons for the raised vegetable bed revival, but probably the most important is more production per square foot of garden. In a traditional home garden, good management may yield about 0.6 pounds of vegetables per square foot. Raised beds do not require the usual space between rows, as no walking is done in the bed to cultivate or harvest. Hence, vegetables are planted in beds at higher densities - ideally spaced just far enough apart to avoid crowding but close enough to shade weeds.

Improved Soil Conditions:

Another reason for greater production in a given space is the improvement of soil conditions. Soil compaction can reduce crop yields up to 50 percent. Water, air and roots all have difficulty moving through soil compressed by tractors, tillers or human feet. Plows, tillers or spades have been the usual answer to this problem, but gardeners can avoid the problem completely by creating beds narrow enough to work from the sides. Soil organic matter content can be increased greatly without getting bogged down.

Raised vegetable beds also help in problem soil situations where compaction is not the only culprit. Homeowners may have low spots unsuited for conventional gardens because of ponding or excessive erosion from runoff. Raised beds rise above these, with frames as a foundation. Soil acidity can thus be more easily maintained in the 5.8 to 6.8 pH range, which is preferable for most vegetable culture.

Ease of Working:

The first, and most important, benefit of gardening with raised beds is the increased ease of timely planting and harvesting. Many people avoid working traditional gardens in rainy weather to avoid compaction and muddy feet. Because raised planting beds are designed for walking around, not in, there is no reason for mud to delay operation. Spaces between beds may be mulched or even paved with stone or brick.

 

Ease of Pest Control:

Pest control also becomes less difficult in raised beds. If burrowing rodents are abundant, the bottom of the bed can be lined with poultry wire or hardware cloth. Rabbits and groundhogs can be discouraged simply by placing their favorite foods in a framed bed with a low fence. The narrow dimensions of vegetable raised beds even make bird netting suspended on flexible conduit frames practical. Weed control with plastic mulch can be achieved economically, as the width of the bed can be spanned by one roll.

Water Conservation:

The narrow dimensions of planter beds are advantageous for water conservation. Canvas soaker hoses, perforated plastic sprinkle hoses and drip-type irrigation disperse water in a long, narrow pattern well-suited to beds. Directing water to the soil helps to reduce disease problems which can result from wetting the foliage with overhead sprinklers.

Construction Tips:

There are only a few guidelines to remember in raised gardening bed construction:

1. Keep the beds narrow and match their length to the site and the watering system. A north-south orientation is best for low-growing crops, allowing direct sunlight to both sides of the bed. Beds that will contain taller crops such as pole beans, trellised peas or caged tomatoes might do better on an east-west axis--lower-growing crops could be planted on the south side of the bed and still get full sun.

2. Avoid the use of creosote or pentachlorophenol-treated lumber for gardening raised bed frames, as these chemicals can leach out and injure plants. Use pressure-treated lumber, redwood, cement block or brick, and be aware that the cement in block will raise soil pH over time. Framing materials can also be large stones, untreated lumber, sapling trees or straight logs. Obviously, colonial farmers did not have all these materials available. You could just hill up the bed and maintain it regularly. In recent years, recycled plastic lumber has become readily available to build a more permanent bed. Depending on the product, it may have 50% sawdust and plastic. Some are nearly 100% plastic. They never need staining or painting and come in lengths similar to lumber.

3. At least one-third of the volume of the bed's root zone should consist of existing soil. Add one-third compost or peat and one-third coarse sand to create a well drained soil. Add a little garden fertilizer and test the soil after the first crop year.

Raised planting bed and vegetable planting beds possibilities are endless. Beds elevated 2 feet or more offer the promise of gardening without bending and can have benches built on the sides for even more convenience. Because a bed warms up quicker than the ground, it can easily double as a cold frame by covering it with a lightweight clear plastic cover. Imagine being able to start plants early in beds with covers and never having to transplant them! Supports for poles, cages and trellises can be mounted to the frame for longer life and ease of installation and removal.

Many of the same principles used in gardening raised beds are being adopted on a larger scale in field crops. Ridge tillage, solid seeding and controlled traffic are all new techniques designed to deal with drainage, weed or compaction problems and to increase productivity. Traditional gardens with orderly rows on wide intervals have mimicked their larger farm counterparts for years. Maybe it is time for them to change their role model to the new farm or the ancient garden.

Gorse (Ulex europaeus) is a spiny, perennial evergreen shrub, considered noxious under the BC Weed Control Act, and thrives on sunny clearings with dry, infertile soil such as sandy or rocky areas, roadsides, fields and pastures, bluffs, cutblocks, and cutbanks. It is currently distributed in Vancouver Island, West Vancouver, some of the Gulf Islands, and Skidegate on the Queen Charlotte Islands.

 

Gorse is a dense evergreen shrub with a single upright stem, spine-like leaves, and fragrant yellow, pea-like flowers. Seedpods are hairy and black. Gorse can grow 1-3 metres in height at maturity.

 

Growing rapidly for the first 15 years, gorse can live up to 45 years. Maturing seedpods explode and disperse up to 18,000 seeds per mature plant. Gorse seeds are easily distributed by ants, animals, birds, and machinery. Since gorse grows mainly by the ocean, water is a common carrier for seeds. Dense patches can hinder re-vegetation of harvested areas and recreational use of land. Gorse can also increase fire hazard as plants contain volatile oils and produce large amounts of litter. Gorse displaces native vegetation, thereby decreasing forage for wildlife and local plant biodiversity.
