What is the Guinea Hog Breed?

The Guinea Hog is a small black pig breed native to America, officially known as the American Guinea Hog since 2006. Its origins remain a mystery, although some theories suggest a possible connection to the Essex pigs from eastern England. However, it should be noted that it is distinct from an older breed called the Guinea Hog or Red Guinea.

The American Guinea Hog is characterized by its rare black coat, sturdy body, curly tail, and upright ears. In North America, there are two types of Guinea hogs: the small-boned and large-boned varieties, with the latter having longer legs. There is also a type of Guinea hog found in South America.

Guinea Hog Origin Facts: History and Heritage of the Breed

  • Guinea Hogs have an intriguing past. It is currently thought that “Guinea” merely refers to its diminutive size, like Guinea Cattle, likewise compact livestock types. 
  • The authentic African Guinea hogs were bigger, red breeds with erect ears, bristly hair, and long tails, suggesting a genetic impact from Nigerian black or Ashanti pigs. In 1804, Thomas Jefferson bought several slave-ship-brought pigs from Africa via the Canary Isles.
  • Guinea hogs were originally black with a tinge of crimson, known as “red Guineas.” By the early 19th century, this variety was extinct. The American Guinea hog, a black Guinea, lost its red tinge but kept its black hue. 
  • Subsistence farmers prized these pigs because they could forage and eat snakes, making the farmyard safer for children and cattle.
  • Guinea hogs became unpopular, endangering extinction. The American Guinea hog’s link to other breeds is still being determined as red Guinea no longer exists. 
  • However, reddish piglets born to bluish-black American Guinea parents suggest a link. The Guinea hog is listed in Slow Food USA’s Ark of Taste, and the American Guinea Hog Association was founded in 2005 to protect the breed.

Guinea Hogs as Pets

Although not as popular as Potbelly pigs or Kunekune pigs, Guinea Hogs are among the smaller pig breeds that can be kept as pets. They have a friendly disposition and are suitable for smaller living spaces. Guinea Hogs offer a choice for those interested in having pigs as pets.

Guinea Hogs Meat Flavour

Guinea Hogs meat is known for its delectable flavor, with a hearty taste and creamy, melt-in-your-mouth fat. It is sweet, buttery, and tender, even when reheated. The American Guinea Hog’s lard-producing qualities make the pork ideal for traditional cuts and for creating excellent charcuterie.

The amount of pork obtained from an individual AGH varies due to differences in size and build, but on average, one can expect to harvest 50-65% of the live hog weight when choosing traditional cuts. The percentage increases when utilizing other hog parts for bone broth, scrapple, head cheese, and jowl bacon.

Lifecycle of Guinea Hogs

The lifecycle of American Guinea Hogs begins with a gestation period of around 114 days. The docile mothers give birth to litters of piglets without assistance, usually creating nests from available materials. Piglets are born small but grow quickly, reaching around 9 to 10 lbs by weaning at 5 to 8 weeks. Male pigs can be castrated at about 14 days of age if desired.

Males can breed at 6 to 8 months, while females can come into heat as early as eight months and give birth near or after their first birthday. Guinea Hogs can have 2 to 2.5 litters per year, with litter sizes ranging from 1 to 14 piglets. Butchering can occur as early as six months, with full size reached at 2 to 3 years, weighing approximately 200 to 300 lbs. They can live a fairly long time, with some reaching 13 or 14 years. It is advisable to breed females earlier to ensure their contribution to the gene pool.
