The Icelandic [a] 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 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 Kleifa. 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 Þoka (Thoka) gene is carried by some ewes, which may give birth to large litters of lambs. A unique strain within the population is the Leader sheep, which carries a hereditary ability or predisposition to lead other sheep safely over dangerous ground. [4] : 827
It is thought that the sheep were introduced to Iceland by Vikings in the late ninth or early tenth century. [4] : 826
Breed numbers reached a peak in 1978, when there were approximately 891 000, or about four sheep for every inhabitant of Iceland. By 2007 the total number had fallen to about 450 000. [5] In 2018 a population of just over 432 000 was reported to DAD-IS. [2]
The colors of Icelandic sheep are inherited in a similar way to those of other sheep, but they display more variety in color and pattern than most other breeds, and some variations are seen which are not seen in other sheep. Each sheep carries three genes that affect the color of the sheep, and each gene has dominant and recessive alleles.[ citation needed ]
Until the 1940s the Icelandic sheep was the predominant milk-producing animal in Iceland. [6] : 32 In the twenty-first century this sheep is reared principally for meat, which accounts for more than 80% of the total income derived from sheep farming. [5]
The fleece is double-coated, with a long outer coat (tog) which gives protection from snow and rain, and a fine inner coat (þel) which insulates the animal against the cold. [4] : 827 The wool of the outer coat has a diameter of about 28–40 microns or sometimes more, and a staple length of some 150–200 mm; the inner coat has a diameter of 19–22 μm or sometimes less, with a staple length in the range 50–100 mm. The two types may be used separately, or spun into a single yarn, lopi , a soft wool which provides good insulation. [4] : 827
The Coopworth is a modern New Zealand breed of sheep. It was developed by researchers at Lincoln College in the Canterbury region of the South Island between about 1956 and 1968, the result of cross-breeding of New Zealand Romney ewes and Border Leicester rams. It has become the second-most numerous sheep breed in New Zealand, and has been exported to Australia, some European countries, and the United States.
The Drysdale is a New Zealand breed of sheep. It was developed from 1931 by Francis Dry, and derives from sheep of the New Zealand Romney breed in which a mutation caused the coat to be particularly hairy, and thus suitable for carpet-making. It is a specialised carpet wool breed, but also a useful meat breed.
The Valais Blacknose, German: Walliser Schwarznasenschaf, 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 Cotswold is a British breed of domestic sheep. It originates in, and is named for, the Cotswold hills of the southern midlands of England. It is a large long-woollen sheep, and is kept as a dual-purpose breed, providing both meat and wool.
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 Ryeland is one of the oldest English sheep breeds going back seven centuries when the monks of Leominster in Herefordshire bred sheep and grazed them on the rye pastures, giving them their name. It was introduced into Australia in 1919 and are classified as an endangered breed by the Rare Breeds Trust of Australia and also are one of the nine heritage breeds that were the foundation of the sheep and wool industry in Australia. The Ryeland was one of the breeds used to introduce the poll gene to the Dorset breed in the development of the Poll Dorset. This breed is raised primarily for meat.
The Lonk is a British breed of domestic sheep. It belongs to the group of black-faced hill breeds of northern England, and is found in the hills of the central and southern Pennines of Lancashire and Yorkshire. It is documented from the mid-eighteenth century; a flock book was started in 1905.
The Oxford Down is a British breed of domestic sheep. It was developed in the 1830s by cross-breeding of Hampshire Down and Southdown ewes with Cotswold rams. It is reared primarily for meat.
The Southdown is a British breed of domestic sheep, the smallest of the British breeds. It is a shortwool breed, and the basis of the whole Down group of breeds. It was originally bred by John Ellman of Glynde, near Lewes in East Sussex, in about 1800. It has been exported to many countries; it has been of particular importance in New Zealand, where it was used in the breeding of Canterbury lamb. In the twenty-first century it is kept principally as a terminal sire.
The Katahdin is a modern American breed of sheep. It is an easy-care sheep: it grows a hair coat with little wool which moults naturally in the spring, and so does not need to be shorn. It is reared for meat only.
The Texel is a Dutch breed of domestic sheep originally from the island of Texel. It is a heavy and muscular sheep, and produces a lean meat carcass. It is polled, clean-faced and clean-legged, with white face and wool. The fibre diameter of the wool averages about 32 μ, with a staple length of 8–15 cm; it is used mainly for knitting and hosiery wools.
The Fries Melkschaap is a Dutch and German breed of dairy sheep. It originates in the Frisia region, which includes parts of both northern Holland and north-western Germany. It has many names: the German stock is known as the Ostfriesisches Milchschaf, or in English as the East Friesian, the East Friesland Milch or the German Milksheep, while the Dutch equivalent is known as the Friesian Milk or Friesian Milksheep, or less often as the Friesian or West Friesian. Under suitable management conditions, it is among the highest-yielding of dairy sheep breeds.
Romanov is a breed of domestic sheep originating from the Upper Volga region in Russia. These domestic sheep got the name Romanov from the town of the same name. In the 18th century, these sheep were first noticed outside of Russia. Soon after, they were imported to Germany and then to France. In 1980, 14 ewes and 4 rams were bought by the Canadian government and were quarantined for 5 years. After the testing, some of the Romanov breed was brought into the United States. The distribution of this unique breed is worldwide. This breed is raised primarily for meat.
The Clun Forest is a breed of domestic sheep originating from the area surrounding the Clun Forest in Shropshire, England. Similar to many of the British breeds of upland sheep, Clun Forest are hardy, adaptable, good foragers, and are long–lived. With sleek heads and wide pelvic structures, Clun Forest ewes lamb easily. The breed has a short to medium–length wool and dark brown faces. They are a multi–purpose animal, kept for meat, wool, and milk. Like other dark faced sheep, Clun produce quality lamb and mutton. However, in contrast to more common meat breeds such as Suffolks, their wool is free of undesirable black fibres and kemp, and is suitable for handspinning. The breed's alert and stylish appearance, together with its reputation for hardiness and fecundity have made it popular with hobby farmers and large commercial flock owners alike. The Official Clun Sheep Breeders Society Show & Sale for males and females is held annually in early September at Ludlow livestock market by McCartneys.
