Polycerates (meaning "many-horned") are animals with more than two horns.
Polycerates (meaning "many-horned") are animals with more than two horns.
Polyceraty has been observed in ancient sheep remains dating to c. 6000 BCE from Çatalhöyük in modern Turkey. [1]
Polycerate sheep breeds include the Hebridean, Icelandic, [2] Jacob, [3] Manx Loaghtan, Boreray and the 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. [4] Because of selective breeding, polycerate sheep are increasingly rare in the British Isles [5] and Spain, [6] but some breeds can still be found in Asia. [7] One example is the black-faced sheep of Tibet. [8]
There have been incidents of polycerate goats (having as many as eight horns), [9] although this is a genetic rarity thought to be inherited. The horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats.
4 horns are the norm for the Austrian goat breed Vierhornziege (four-horned goat). [10]
Antelopes can also be polycerate, for example, the blue wildebeest (Connochaetes taurinus). Both sexes normally possess one pair of large curved horns. [11]
Cerastes, a legendary Greek horned serpent, is sometimes described with two horns or with four small ones.
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, yaks, bison, buffalo, antelopes, sheep and goats. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene.
The Manx Loaghtan is a rare breed of sheep 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.
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 horns arise from subcutaneous connective tissue and later fuse to the underlying frontal bone.
The Valais Blacknose is a breed of domestic sheep originating in the Valais region of Switzerland. It is a dual-purpose breed, raised both for meat and for wool. The Valais Blacknose has been dubbed as "cutest sheep in the world."
The Navajo-Churro, or Churro for short, is a breed of domestic sheep originating with the Spanish Churra sheep obtained by the Diné around the 16th century during the Spanish Conquest. Its wool consists of a protective topcoat and soft undercoat. Some rams have four fully developed horns, a trait shared with few other breeds in the world. The breed is highly resistant to disease. Ewes often birth twins, and they have good mothering instincts. This breed is raised primarily for wool, although some also eat their meat.
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 Shropshire breed of domestic sheep originated from the hills of Shropshire, and North Staffordshire, England, during the 1840s. The breeders in the area used the local horned black-faced sheep and crossed them with a few breeds of white-faced sheep. This produced a medium-sized polled (hornless) sheep that produced good wool and meat. In 1855 the first Shropshires were imported into the United States (Virginia). This breed is raised primarily for meat.
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 horns. They were often formerly known as "St Kilda" sheep, although unlike Soay and Boreray sheep they are probably not in fact from the St Kilda archipelago.
The Awassi is a local fat-tailed sheep breed in South-West Asia originated in the Syro-Arabian desert. Other local names can also be Arab, Baladi, Deiri, Syrian, Ausi, Nuami, Gezirieh, or Ivesi (Turkish). It is multi coloured: white with brown head and legs. The ears are long and drooping.
Polled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC.
The Dorset Horn is an endangered British breed of domestic sheep. It is documented from the seventeenth century, and is highly prolific, sometimes producing two lambing seasons per year. Among British sheep, it is the only breed capable of breeding throughout the winter.
Dehorning is the process of removing the horns of livestock. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons. Disbudding is a different process with similar results; it cauterizes and thus destroys horn buds before they have grown into horns. Disbudding is commonly performed early in an animal's life, as are other procedures such as docking and castration. In some cases, it can be unnecessary.
The Shetland is a small, wool-producing breed of sheep originating in the Shetland Isles, Scotland, but is now also kept in many other parts of the world. It is part of the Northern European short-tailed sheep group, and it is closely related to the extinct Scottish Dunface. Shetlands are classified as a landrace or "unimproved" breed. This breed is kept for its very fine wool, for meat, and for conservation grazing.
The Norfolk Horn is one of the British black-faced sheep breeds. It differs from other black-faced breeds, which are mainly found in high-rainfall, upland areas, and from most other modern, lowland British sheep breeds in being lightly built and very hardy. This breed is raised primarily for meat.
The Golden Guernsey is a rare breed of dairy goat from Guernsey in the Channel Islands, where it has been known for more than two hundred years.
The Whitefaced Woodland is a sheep breed from the Woodlands of Hope an area in the South Pennines in England. It is a combination of two breeds, the Woodland and the Penistone sheep after the Yorkshire town where sheep sales have been held since 1699. It is thought to be closely related to the Swaledale and the Lonk. Substantial commercial flocks of the Whitefaced Woodland are kept in its region of origin, but it is listed as a vulnerable breed by the Rare Breeds Survival Trust, since there are fewer than 900 registered breeding females in Great Britain.
The goat or domestic goat is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago.
The Northern European short-tailed sheep are a group of traditional sheep breeds or types found in Northern Europe, mainly in the British Isles, Scandinavia, Iceland, Greenland, and the area around the Baltic. They are thought to be derived from the first sheep brought to Europe by early farmers, and for thousands of years they were the only type of sheep kept in Northern Europe. They are hardy sheep, adapted to harsh environments, but they are small and have been replaced in most areas with later types of larger, long-tailed sheep.
The Newfoundland, also called the Newfoundland Local, is a breed of sheep native to Newfoundland.
The Polled Dorset is an American breed of domestic sheep. It is a polled (hornless) variant of the British Dorset Horn. It was developed at the North Carolina State University Small Ruminant Unit in the 1950s after a genetic mutation led to the birth of a polled ram. After some years of breeding work, a true-breeding polled strain was established.
