The North Ronaldsay or Orkney is a breed of sheep from North Ronaldsay, the northernmost island of Orkney, off the north coast of Scotland. It belongs to the Northern European short-tailed sheep group of breeds, and has evolved without much cross-breeding with modern breeds. It is a smaller sheep than most, with the rams (males) horned and ewes (females) mostly hornless. It was formerly kept primarily for wool, but now the two largest flocks are feral, one on North Ronaldsay and another on the Orkney island of Auskerry. The Rare Breeds Survival Trust lists the breed as a priority on its 2021–2022 watchlist, and they are in danger of extinction, with fewer than 600 registered breeding females in the United Kingdom.
The Randall Lineback or Randall is an American breed of cattle. It originated in Bennington County, Vermont, and is critically endangered.
The Dominique is an American breed of chicken, characterized by black-and-white barred plumage and a rose comb. It is considered to be the oldest American chicken breed, and is thought to derive from birds brought to America by colonists from southern England. It was well known by about 1750, and by the mid-nineteenth century was widely distributed in the eastern United States. It is a dual-purpose breed, but is kept principally for its brown eggs. It became an endangered breed in the twentieth century, but numbers have since recovered.
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 San Clemente Island goat is a type of domestic goat derived from feral goats isolated on San Clemente Island, one of the Channel Islands of California.
The Livestock Conservancy, formerly known as the American Livestock Breeds Conservancy (ALBC) and prior to that, the American Minor Breeds Conservancy, is a nonprofit organization focused on preserving and promoting rare breeds, also known as "heritage breeds" of livestock. Founded in 1977, through the efforts of livestock breed enthusiasts concerned about the disappearance of many of the US's heritage livestock breeds, The Livestock Conservancy was the pioneer livestock preservation organization in the United States, and remains a leading organization in that field. It has initiated programs that have saved multiple breeds from extinction, and works closely with similar organizations in other countries, including Rare Breeds Canada. With 3,000 members, a staff of eleven and a 19-member board of directors, the organization has an operating budget of over a million dollars.
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 Portland is a sheep breed that takes its name from the Isle of Portland in Dorset, England. This breed is raised primarily for meat.
Santa Cruz sheep are an extremely rare breed of domestic sheep that once existed as a feral population on the Santa Cruz Island of the Channel Islands of California. Small and hardy, the sheep were all killed or removed from the island to prevent destruction of natural habitats. Today, they number fewer than 200 animals. This breed is primarily raised for wool.
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 Choctaw Hog is a breed of domestic pig historically used by Native Americans. They are now reduced in population to some hundred animals, most of them in the Choctaw Nation of Oklahoma. The American Livestock Breeds Conservancy calls the Choctaw Hog's status "critically rare" and says it "is a high conservation priority."
In modern agriculture, a rare breed is a breed of poultry or livestock that has a very small breeding population, usually from a few hundred to a few thousand. Because of their small numbers, rare breeds may have a threatened conservation status, and they may be protected under regional laws. Many countries have organizations devoted to the protection and promotion of rare breeds, for which they each have their own definition. In botany and horticulture, the parallel to rare animal breeds are heirloom plants, which are rare cultivars.
The Florida Cracker or Florida Scrub is an American breed of cattle. It originated in Spanish Florida and later in the American state of Florida, and is named for the Florida cracker culture in which it was kept. It is one of the Criollo breeds that descend from the Spanish cattle originally brought to the Americas by the Spanish Conquistadors; among the other North American breeds in this group are the Pineywoods, the Corriente and Texas Longhorn. Unlike the Pineywoods – to which it is closely related – the Florida Cracker has not been inter-bred with breeds of North European origin.
The Newfoundland, also called the Newfoundland Local, is a breed of sheep native to Newfoundland.
The Romeldale is an American breed of domestic sheep. It derives from cross-breeding of Romney rams and Rambouillet ewes from about 1915. The California Variegated Mutant is a rare badger-faced or variegated sub-type of the Romeldale. Some sources, as well as the breed association, refer to the two together as Romeldale/CVM.
The Ossabaw Island Hog or Ossabaw Island is a breed of pig derived from a population of feral pigs on Ossabaw Island, Georgia, United States. The original Ossabaw hogs are descended from swine released on the island in the 16th century by Spanish explorers. A breeding population has been established on American farms off the island, but they remain a critically endangered variety of pig.
The Guinea Hog is an American breed of small black pig. Since 2006 it has officially been named the American Guinea Hog. Its origins are unknown; a connection to the Essex pigs of eastern England has been suggested. It is apparently unconnected to an older pig also known as Guinea Hog or Red Guinea, which disappeared in the late nineteenth century.
The Hereford Hog or Hereford is an American breed of domestic pig. It is named for its color and pattern, which is similar to that of the Hereford breed of cattle: red with a white face.
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.
The Devon and Cornwall Longwool is a British breed of domestic sheep from South West England. It was created in 1977 through merger of two local breeds, the Devon Longwool and the South Devon.
