Sus is the genus of wild and domestic pigs, within the even-toed ungulate family Suidae. Sus include domestic pigs and their ancestor, the common Eurasian wild boar, along with other species. Sus species, like all suids, are native to the Eurasian and African continents, ranging from Europe to the Pacific islands. Suids other than the pig are the babirusa of Indonesia, the pygmy hog of South Asia, the warthogs of Africa, and other pig genera from Africa. The suids are a sister clade to peccaries.
A feral pig is a domestic pig which has gone feral, meaning it lives in the wild. The term feral pig has also been applied to wild boars, which can interbreed with domestic pigs. They are found mostly in the Americas and Australia. Razorback and wild hog are Americanisms applied to feral pigs or boar–pig hybrids.
The pig, often called swine, hog, or domesticpig when distinguishing from other members of the genus Sus, is an omnivorous, domesticated, even-toed, hoofed mammal. It is variously considered a subspecies of Sus scrofa or a distinct species. The pig's head-plus-body length ranges from 0.9 to 1.8 m, and adult pigs typically weigh between 50 and 350 kg, with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed. Compared to other artiodactyls, a pig's head is relatively long and pointed. Most even-toed ungulates are herbivorous, but pigs are omnivores, like their wild relative. Pigs grunt and make snorting sounds.
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 grice was a breed of swine found in the Highlands and Islands of Scotland and in Ireland. It became extinct, surviving the longest in the Shetland Isles, where it disappeared sometime between the middle of the 19th century and the 1930s. It was also known as the Highland, Hebridean or Irish pig.
Mulefoot are a breed of domestic pig which is named for its intact, uncloven hooves reminiscent of a mule.
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 Large Black pig is a British breed of domestic pig. It is the only British pig that is entirely black. It was created in the last years of the nineteenth century by merging the black pig populations of Devon and Cornwall in the south-west with those of Essex, Suffolk and Kent in the south-east. It is hardy, docile and prolific; it forages well and is suitable for extensive farming, but not well suited to intensive management.
Hog Island sheep are a breed of sheep descended from animals first brought to Virginia's Hog Island in the 18th century. During the 1930s and 1940s, storm conditions forced the island's residents to evacuate, leaving some sheep behind. These sheep adapted to the environment free of human intervention, becoming feral.
Pig farming or pork farming or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food and skins.
The Red Wattle Hog is a breed of domestic pig originating in the United States. It is named for its red color and distinctive wattles or tassels, and is on the threatened list of the American Livestock Breeds Conservancy (ALBC).
The Mangalica is a Hungarian breed of domestic pig. It was developed in the mid-19th century by crossbreeding breeds from the nearby Romanian Salonta and Hungarian Bakony with the European wild boar and the Serbian Šumadija breed. The Mangalica pig grows a thick, curly coat of hair. The only other pig breed noted for having a long coat is the extinct Lincolnshire Curly Coat pig of England.
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."
A heritage turkey is one of a variety of strains of domestic turkey which retains historic characteristics that are no longer present in the majority of turkeys raised for consumption since the mid-20th century. Heritage turkeys can be differentiated from other domestic turkeys in that they are biologically capable of being raised in a manner that more closely matches the natural behavior and life cycle of wild turkeys. Heritage turkeys have a relatively long lifespan and a much slower growth rate than turkeys bred for industrial agriculture, and unlike industrially bred turkeys, can reproduce without artificial insemination.
The Norfolk Black, also known as the Black Spanish or Black Turkey, is a British breed of domestic turkey. It is thought to derive from birds taken to Britain from Spain, where they had arrived with Spanish explorers returning from the New World.
The American Milking Devon is an American breed of dual-purpose cattle, reared both for milk and for beef. It derives from the Devon cattle of the United States, which in turn are derived from the North Devon cattle of south-west England. It was established as a separate breed in 1978 with the formation of the American Milking Devon Cattle Association, after the breeding aims of the Devon were concentrated almost exclusively on beef production. It is a rare breed: its conservation status is listed as by the Livestock Conservancy as 'critical'.
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.
Risk assessment for organic swine health is the process of evaluating the likelihood and potential impact of various factors that may affect the health and well-being of organic swine. Risks associated with organic swine farming may differ to those associated with non-organic swine farming, and is of increasing relevance due to growth in the sector. While organic swine farming makes up a small share of U.S. swine farming overall, numbers have increased significantly in recent years. Additionally, non-certified organic swine herds are not accounted in official statistics. Consumer demand, stemming from the larger organic agriculture movement has helped spur growth in this industry.
