Horned
A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct from antlers, which are not permanent. In mammals, true horns are found mainly among the ruminant artiodactyls, in the families Antilocapridae (pronghorn) and Bovidae (cattle, goats, antelope etc.). Cattle horns arise from subcutaneous connective tissue (under the scalp) and later fuse to the underlying frontal bone. One pair of horns is usual; however, two or more pairs occur in a few wild species and in some domesticated breeds of sheep. Polycerate (multi-horned) sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, and the Navajo-Churro. Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, which shed th ...

Jacob Sheep
The Jacob is a British breed of domestic sheep. It combines two characteristics unusual in sheep: it is piebald—dark-coloured with areas of white wool—and it is often polycerate or multi-horned. It most commonly has four horns. The origin of the breed is not known; broken-coloured polycerate sheep were present in England by the middle of the seventeenth century, and were widespread a century later. A breed society was formed in 1969, and a flock book was published from 1972. The Jacob was kept for centuries as a "park sheep", to ornament the large estates of landowners. In modern times it is reared mainly for wool, meat and skins. History The origins of the Jacob are not known. It has been bred in the British Isles for several hundred years. Sheep of this kind, little different from the modern breed, were shown in paintings from about 1760 at Tabley House in Cheshire, and – by George Stubbs – at Wentworth Woodhouse in Yorkshire. In the de Tabley family, the tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycerate
Polycerates (meaning "many-horned") are animals with more than two horn (anatomy), horns. Sheep Polyceraty has been observed in ancient sheep remains dating to 6000 BCE from Çatalhöyük in modern Turkey. Polycerate sheep breeds include the Hebridean sheep, Hebridean, Icelandic sheep, Icelandic, Jacob (sheep), Jacob, Manx Loaghtan, Boreray (sheep), Boreray and the Navajo-Churro sheep, Navajo-Churro. One example of a polycerate Shetland sheep was a ram kept by US President Thomas Jefferson for several years in the early 19th century in front of the White House. In the spring of 1808 this ram attacked several people who had taken shortcuts across the square, injuring some and actually killing a small boy. Because of selective breeding, polycerate sheep are increasingly rare in the British Isles and Spain, but some breeds can still be found in Asia. One example is the black-faced sheep of Tibet. Goats There have been incidents of polycerate goats (having as many as eight horns), a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hebridean Sheep
The Hebridean is a breed of small black sheep from Scotland, similar to other members of the Northern European short-tailed sheep group, having a short, triangular tail. They often have two pairs of horn (anatomy), horns. They were formerly known as "St Kilda" sheep, because they were exported from the St Kilda archipelago in the 19th century to serve as parkland livestock Characteristics 
Modern Hebrideans have black, rather coarse wool, which fades to brown in the sun and often becomes grey with age; there is no wool on the face or legs. If not shorn the wool may moulting, moult naturally in spring. Rams and ewes typically have one pair of H ...

Manx Loaghtan
The Manx Loaghtan ( ) is a rare breed of sheep (''Ovis aries'') native to the Isle of Man. It is sometimes spelled as ''Loaghtyn'' or ''Loghtan''. The sheep have dark brown wool and usually four or occasionally six horns. The Manx Loaghtan is one of the Northern European short-tailed sheep breeds, and descends from the primitive sheep once found throughout Scotland, the Hebrides, and Shetland Islands. The word Loaghtan comes from the Manx words ''lugh dhoan'', which mean mouse-brown and describe the colour of the sheep. This breed is primarily raised for its meat, which some consider a delicacy. In 2008, the meat received EU recognition and protection under the Protected Designation of Origin scheme, which requires products with a regional name to originate in the named region. The Rare Breeds Survival Trust has characterised the Loaghtan as "at risk". By the 1950s there were only 43 surviving specimens. Manx National Heritage developed two healthy flocks. These have given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scur
A scur is an incompletely developed horn growth. In cattle, scurs are not attached to the skull, whereas horns are attached and have blood vessels and nerves. Scurs may also occur in sheep and goats. Genetic Inheritance The gene for scurs is inherited separately from the polled gene in cattle. Not all polled animals lack the scur gene. Since horned is recessive to polled, no horned cattle carry the polled allele, but they may also carry scurs. In cattle, genetic expression of the scur gene is different from that of the dominant polled gene, in that the scur gene's expression depends on the sex of the animal. The scur gene is dominant in males and recessive in females.

Bovidae
The Bovidae comprise the family (biology), biological family of cloven-hoofed, ruminant mammals that includes Bos, cattle, bison, Bubalina, buffalo, antelopes (including Caprinae, goat-antelopes), Ovis, sheep and Capra (genus), goats. A member of this family is called a bovid. With 143 Extant taxon, extant species and 300 known Extinction, extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and Fur, pelage colouration. Except some Polled livestock, domesticated forms, all male bovids have two or more horn (anatomy), horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artiodactyl
Artiodactyls are placental mammals belonging to the order Artiodactyla ( , ). Typically, they are ungulates which bear weight equally on two (an even number) of their five toes (the third and fourth, often in the form of a hoof). The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, most perissodactyls bear weight on an odd number of the five toes. Another difference between the two orders is that many artiodactyls (except for Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine (as perissodactyls do). Molecular biology, along with new fossil discoveries, has found that cetaceans (whales, dolphins, and porpoises) fall within this taxonomic branch, being most closely related to hippopotamuses. Some modern taxonomists thus apply the name Cetartiodactyla () to this group, while others opt to include cetaceans within the existing name of Artiodactyla. Some researchers use "even-toed ungulates" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antelope
The term antelope refers to numerous extant or recently extinct species of the ruminant artiodactyl family Bovidae that are indigenous to most of Africa, India, the Middle East, Central Asia, and a small area of Eastern Europe. Antelopes do not form a monophyletic group, as some antelopes are more closely related to other bovid groups, such as bovines, goats, and sheep, than to other antelopes. A stricter grouping, known as the true antelopes, includes only the genera '' Gazella'', '' Nanger'', '' Eudorcas'', and '' Antilope''. One North American mammal, the pronghorn or "pronghorn antelope", is colloquially referred to as the "American antelope", despite the fact that it belongs to a completely different family ( Antilocapridae) than the true Old-World antelopes; pronghorn are the sole extant member of an extinct prehistoric lineage that once included many unique species. Although antelope are sometimes referred to, and easily misidentified as, "deer" ( cervids), true ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spur (zoology)
A spur is an outgrowth of bone covered in a sheath of horn found in various anatomical locations in some animals. Unlike claws or nails, which grow from the tip of the toes, spurs form from other parts of the foot, usually in connection with joints where the toes meet the foot or the foot meets the long bones. Spurs are most commonly found on the hindfeet, though some birds possess spurs at the leading edge of the wings. Anatomy A spur is much like a true horn; it is a bony core attached to the skeleton and has an outer horny layer. Like horns, the spur grows from the base outwards, so the tip is older than the base. Some spurs form as an outgrowth of an existing bone, though most are secondarily formed as dermal bone hinged to the skeleton through a semi-rigid joint. Spurs on the hind-feet do not appear to molt, but the wing spurs of birds are molted once a year along with the wing feathers. Unlike claws, spurs are normally straight or only slightly curved, making them s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icelandic Sheep
The Icelandic is the Icelandic breed of domestic sheep. It belongs to the Northern European Short-tailed group of sheep, and is larger than most breeds in that group. It is thought to have been introduced to Iceland by Vikings in the late ninth or early tenth century. It is generally short-legged and stocky, slender and light-boned, and usually horned, although polled and polycerate animals can occur; there is a polled strain, the . The fleece is double-coated and may be white or a variety of other colors; the face and legs are without wool. The sheep are highly resistant to cold, and are generally left unshorn for the winter. Icelandic ewes are highly prolific, with a lambing percentage of 175–220%. The (Thoka) gene is carried by some ewes, which may give birth to large litters of lambs. A unique strain within the population is the Leadersheep, which carries a hereditary ability or predisposition to lead other sheep safely over dangerous ground. History It is thoug ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, bovid ungulates widely kept as livestock. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus '' Bos''. Mature female cattle are called cows and mature male cattle are bulls. Young female cattle are called heifers, young male cattle are oxen or bullocks, and castrated male cattle are known as steers. Cattle are commonly raised for meat, for dairy products, and for leather. As draft animals, they pull carts and farm implements. Cattle are considered sacred animals within Hinduism, and it is illegal to kill them in some Indian states. Small breeds such as the miniature Zebu are kept as pets. Taurine cattle are widely distributed across Europe and temperate areas of Asia, the Americas, and Australia. Zebus are found mainly in India and tropical areas of Asia, America, and Australia. Sanga cattle are found primarily in sub-Saharan Africa. These types, sometime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goat
The goat or domestic goat (''Capra hircus'') is a species of Caprinae, goat-antelope that is mostly kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the family Bovidae, meaning it is closely related to the sheep. It was one of the first animals to be domesticated, in Iran around 10,000 years ago. Goats have been used for milk, Goat meat, meat, Animal fur, wool, and Animal skin, skins across much of the world. Milk from goats is often turned into goat cheese, cheese. In 2022, there were more than 1.1 billion goats living in the world, of which 150 million were in India. Goats feature in mythology, folklore, and religion in many parts of the world, including in the classical myth of Amalthea (mythology), Amalthea, in Tanngrisnir and Tanngnjóstr, the goats that pulled the chariot of the Norse god Thor, in the Scandinavian Yule goat, and in Hinduism's goat-headed Daksha.
