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. [5] : 800
The Dorset Horn originated in Dorset in south-west England. Like the extinct Pink-nosed Somerset, to which it is related, it probably derived from cross-breeding of Merinos imported from Spain with local tan-faced sheep similar to the modern Portland. [4] [5] : 800 Unlike many British lowland breeds, Dorset sheep were not influenced by cross-breeding with the Leicester or Southdown breeds which were much used for this purpose in the latter eighteenth and early nineteenth centuries. [5] : 800 A breeders' society, the Dorset Horn Sheep Breeders' Association, was set up in 1891 [7] and the first flock book was published in the following year. [8] [3]
The Dorset Horn was exported to many countries, among them Australia, South Africa and the United States, where the first arrivals were in the 1860s, and where substantial numbers were imported from about 1880. [5] : 800 The Dorset Horn reached Australia in 1895, [9] and New Zealand in 1897. [10] In 2023 it was reported to DAD-IS by twenty countries in Africa, the Americas, Asia, Europe and Oceania; the largest population reported was that of Denmark, where there were 1191 head. [11]
A polled variant of the breed, the Poll Dorset, was bred in Australia through cross-breeding with the hornless Corriedale and Ryeland breeds. From about 1950, this was introduced to the United Kingdom, where it rapidly supplanted the horned variant; [5] : 800 the breed association changed its name in 1981 to the Dorset Horn and Poll Dorset Sheep Breeder's Association, and registers both breeds. [7] A different polled variant of the breed arose in the United States, derived from a polled sport in a flock kept by North Carolina State University. This Polled Dorset was registered with the breed association – the Continental Dorset Club – from 1956; as elsewhere, it soon became more widespread than the original horned type. [12]
The world-wide conservation status of the Dorset Horn was listed by the FAO as "not at risk" in 2007. [1] : 147 At country level, it is listed as "vulnerable" by the Rare Breeds Trust of Australia, [9] as "priority" by the Rare Breeds Conservation Society of New Zealand, [10] and as "threatened" by the Livestock Conservancy in the USA. [12] In the United Kingdom, where in the 1980s there were more than 100000 breeding ewes, [5] : 800 its status is listed by the Rare Breeds Survival Trust as "at risk", meaning that the total number is between 900 and 1500 head. [2]
The Dorset Horn has contributed to the development of several other breeds: the Dorper and Dormer breeds of South Africa, through cross-breeding with the Blackhead Persian and Merinos respectively; and the British Milksheep and Cadzow Improver in the United Kingdom. [5] : 800 [13]
The Dorset Horn is white-woolled and white-faced; the nostrils are a characteristic pink. It is horned in both sexes, with heavy spiral horns on rams. The fleece is thick, with a weight of 2.25 to 3 kg, a staple length of 80–100 mm, and a Bradford count of 54s–58s. [4]
The Longhorn or British Longhorn is a British breed of beef cattle characterised by long curving horns. It originated in northern England, in the counties of Lancashire, Westmorland and Yorkshire, and later spread to the English Midlands and to Ireland. It was originally a slow heavy draught animal; cows gave a little milk, although high in fat. In the eighteenth century Robert Bakewell applied his methods of selective breeding to these cattle, which for a short time became the predominant British breed. Both the numbers and the quality of the breed declined throughout the nineteenth century and for much of the twentieth. A breed society was formed in 1878, and a herd-book published in that year.
The Galloway is a Scottish breed of beef cattle, named after the Galloway region of Scotland, where it originated during the seventeenth century.
The Dairy Shorthorn is a British breed of dairy cattle. It derives from the Shorthorn cattle of Tees-side, in the North Riding of Yorkshire and in Northumbria in north-eastern England. The Shorthorn was for this reason at first known as the Durham or Teeswater.
The Blackface or Scottish Blackface is a British breed of sheep. It is the most common sheep breed of the United Kingdom. Despite the name, it did not originate in Scotland, but south of the border.
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 Belted Galloway is a traditional Scottish breed of beef cattle. It derives from the Galloway cattle of the Galloway region of south-western Scotland, and was established as a separate breed in 1921. It is adapted to living on the poor upland pastures and windswept moorlands of the region. The exact origin of the breed is unclear, although the white belt for which they are named, and which distinguishes the breed from black Galloway cattle, is often surmised to be the result of cross-breeding with the similarly-coloured Dutch Lakenvelder breed.
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 Tamworth is a British breed of domestic pig. It is the only red-coloured British pig. Its origins are unknown, but it appears to have developed near the town of Tamworth in south-eastern Staffordshire, close to Warwickshire border. It is one of seven British pig breeds listed by the Rare Breeds Survival Trust as 'priority', the highest level of concern of the trust.
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 Bourbon Red is an American breed of domestic turkey. It is named for its reddish-brown plumage and for its area of origin, Bourbon County, Kentucky, where it was developed in the last years of the nineteenth century. It was accepted into the Standard of Perfection of the American Poultry Association in 1909, and in the early twentieth century was an important commercial meat breed until the Broad Breasted White began to dominate industrial production. The Bourbon Red is considered a heritage turkey; it is an endangered breed, classified as 'watch' by the Livestock Conservancy. It was formerly known as the Bourbon Butternut or as the Kentucky Red.
The Berkshire is a British breed of pig. It originated in the English county of Berkshire, for which it is named. It is normally black, with some white on the snout, on the lower legs, and on the tip of the tail.
The Sussex is a British breed of red beef cattle from the Weald of Sussex, Surrey and Kent, in south-eastern England. Its traditional use as a draught ox on the Weald continued into the twentieth century. From the late nineteenth century it began to be selectively bred for beef production. It has been exported to many countries of the world; the largest population is in South Africa, where there may be half a million head.
The Wensleydale is a British breed of domestic sheep. It is named for the Wensleydale region of North Yorkshire, in the north of England, where it was bred in the early nineteenth century by cross-breeding a Dishley Leicester ram with local long-woolled sheep of a breed that is now extinct. It has a blue-grey face and long purled wool, and is among the heaviest of British sheep breeds. It is an endangered breed, and is categorised as "at risk" by the Rare Breeds Survival Trust. It is often used as a ram breed to cross with other breeds to obtain market lambs, and for its high-quality wool.
The Lincoln Red is a British breed of red-coated beef cattle. It originates in, and is named for, the county of Lincolnshire in the eastern Midlands of England. It was selectively bred in the late eighteenth and early nineteenth centuries by crossing large local draught cattle of the region with Teeswater Shorthorns of medium size. It was at first known as the Lincolnshire Red Shorthorn, and was a dual-purpose breed, reared both for milk and for beef. The polling gene was introduced in the early twentieth century, and the cattle are now usually polled; the word 'shorthorn' was dropped from the breed name in 1960. In the twenty-first century it is reared for beef.
The Boreray, also known as the Boreray Blackface or Hebridean Blackface, is a breed of sheep originating on the St Kilda archipelago off the west coast of Scotland and surviving as a feral animal on one of the islands, Boreray. The breed was once reared for meat and wool, but is now used mainly for conservation grazing. The Boreray is one of the Northern European short-tailed sheep group of breeds.
The Devon Closewool is a British breed of domestic sheep. It is distributed almost exclusively on Exmoor in North Devon, in south-west England. It is raised primarily for meat.
The Middle White is a British breed of domestic pig. It originated in Yorkshire, and derived from the Large White and the now-extinct Small White. It was recognised in 1852, and the first herd-book was published in 1884. It is a porker, reared for fresh pork, and is characterised by a short and sharply-upturned snout. After the Second World War it came close to extinction; although numbers have recovered somewhat, it is listed by the Rare Breeds Survival Trust as "priority" – the highest level of risk.
The Devon Longwool was a British breed of domestic sheep from south-west England. It was distributed in southern Somerset and northern Devon, and was – like the Greyface Dartmoor and the South Devon – a polled longwool sheep. It is now considered extinct, as in 1977 it was merged with the South Devon to form the Devon and Cornwall Longwool.
The Blue Albion was a British breed of cattle with an unusual blue roan coat. It originated in the English Midlands in the late nineteenth or early twentieth century, and was a dual-purpose breed, reared both for beef and for milk. It became extinct following the foot-and-mouth outbreak of 1967.
