A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. In literature, there exist several slightly deviating definitions. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. It was shown by set-theoretic means that for the term breed an infinite number of different definitions, which more or less meet the common requirements found in literature, can be given. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset.
Breeding back is a form of artificial selection by the deliberate selective breeding of domestic animals, in an attempt to achieve an animal breed with a phenotype that resembles a wild type ancestor, usually one that has gone extinct. Breeding back is not to be confused with dedomestication.
The Brahman is an American breed of zebuine-taurine hybrid beef cattle. It was bred in the United States from 1885 from cattle originating in India, imported at various times from the United Kingdom, from India and from Brazil. These were mainly Gir, Guzerá and Nelore stock, with some Indu-Brasil, Krishna Valley and Ongole. The Brahman has a high tolerance of heat, sunlight and humidity, and good resistance to parasites. It has been exported to many countries, particularly in the tropics; in Australia it is the most numerous breed of cattle. It has been used in the creation of numerous taurine-indicine hybrids, some of which – such as the Brangus and Brahmousin – are established as separate breeds.
A landrace is a domesticated, locally adapted, traditional variety of a species of animal or plant that has developed over time, through adaptation to its natural and cultural environment of agriculture and pastoralism, and due to isolation from other populations of the species. Landraces are generally distinguished from cultivars, and from breeds in the standardized sense, although the term landrace breed is sometimes used as distinguished from the term standardized breed when referring to cattle.
The Nigerian Dwarf is an American breed of dwarf goat. Like the American Pygmy Goat, it derives from the West African Dwarf group of breeds of West Africa.
The Blonde d'Aquitaine is a modern French breed of large domestic beef cattle. It was created in 1962 by merging three blonde draught breeds of south-western France, the Blonde des Pyrénées, the Blonde de Quercy and the Garonnaise. Since about 1970 it has been selectively bred specifically for beef production. It is the third-most numerous beef breed of France, after the Charolais and the Limousin. It has been exported to many countries round the world.
The Pinzgauer is a breed of domestic cattle from the Pinzgau region of the federal state of Salzburg in Austria. It has distinctive colouring, with chestnut-brown sides and white back and underside. It was in the past a triple-purpose breed, raised for meat, milk and draught use. There is a naturally polled sub-type, the Jochberg Hummel. In 2007 the breed was not considered by the FAO to be at risk.
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 Vladimir Heavy Draft is a Russian breed of heavy draught horse. It was bred in the early twentieth century in farms and collectives in Ivanovo Oblast and Vladimir Oblast, to the east of Moscow. The most important influence on the development of the breed was from three Clydesdale stallions foaled between 1910 and 1923. The Vladimir was officially recognised in 1946.
The Karabair,, is a long-established horse breed from Central Asia, and particularly from Uzbekistan and northern Tajikistan. It results from the cross-breeding of desert horses of Arabian or Turkmene type from the south with steppe horses from the north. It is a small, agile and versatile horse that can be used for riding or driving. It is well suited to local horse sports, and especially to the Uzbek national game, kokpar. It is also used for meat and milk production; the milk may be made into kumis.
The Kazakh Whiteheaded is a breed of beef cattle from Kazakhstan and Russia. The breed was developed between 1930 and 1950 on state farms in the Kazakh republic and the Lower Volga by crossing Hereford cattle with local Kazakh and Kalmyk stock. The breed resembles the Hereford in colour and conformation while incorporating the hardiness of the local breeds. In 1990 the population of the breed in Kazakhstan was estimated at 1,334,000.
The Aksai Black Pied is a distinctively black and white spotted pig breed from Kazakhstan.
The British Saddleback is a modern British breed of domestic pig. It was created in 1967 by merging the surviving populations of two traditional saddleback breeds, the Essex and Wessex Saddleback.
The Dutch Landrace is a traditional Dutch breed of domestic goat. It has been known in the Netherlands since the seventeenth century, and was formerly numerous there. It came close to extinction in the 1950s, but was saved by cross-breeding with unrelated goats, and by 2020 numbered over 2000 head.
The Yakutian or Yakut is a native horse breed from the Siberian Sakha Republic region. It is large compared to the otherwise similar Mongolian horse and Przewalski's horse. It is noted for its adaptation to the extreme cold climate of Yakutia, including the ability to locate and graze on vegetation that is under deep snow cover, and to survive without shelter in temperatures that reach −70 °C (−94 °F).
The Italian Landrace is an Italian breed of domestic pig. It derives from the Danish Landrace breed developed in Denmark at the end of the nineteenth century. Stock was imported into Italy after the Second World War. The breed has been selected principally for suitability for the production of prosciutto crudo. It is, after the Large White Italiana, the second-most numerous pig breed in Italy. The breed standard is issued by the Ministero delle Politiche Agricole Alimentari e Forestali, the Italian ministry of agriculture and forestry; the herdbook is kept by the Associazione Nazionale Allevatori Suini, the national pig-breeders' association.
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.
The Mora Romagnola is a breed of pig from Emilia-Romagna, in northern Italy. It may also be called Mora, Bruna Romagnola, Castagnina or Forlivese. It is raised principally in Emilia–Romagna, but also in Campania, Friuli–Venezia Giulia, Lombardy, the Marche, Piemonte and the Veneto. It is one of the six autochthonous pig breeds recognised by the Ministero delle Politiche Agricole Alimentari e Forestali, the Italian ministry of agriculture and forestry.
The Bleue du Nord is a French breed of dual-purpose cattle from the former region of Nord-Pas-de-Calais in the north-east of the country, on the border with Belgium. It shares the origins of the Belgian Blue, but unlike that breed is selectively bred both for meat and for dairy use. The "double-muscling" characteristic of the Belgian Blue, caused by a genetic myostatin deficiency, is present also in the Bleue du Nord, but to a limited and controlled extent.
The Japanese Polled is a critically-endangered breed of small Japanese beef cattle. It is one of six native Japanese cattle breeds, and one of the four Japanese breeds known as wagyū, the others being the Japanese Black, the Japanese Brown and the Japanese Shorthorn. All wagyū cattle derive from cross-breeding in the early twentieth century of native Japanese cattle with imported stock, mostly from Europe. In the case of the Japanese Polled, the principal foreign influence was from the Scottish Angus breed.
