The Large Black, occasionally called the Devon or Cornwall Black, is a breed of domestic pig native to Great Britain, particularly Devon, Cornwall and Essex. The Large Black is accurately named, as it is a large swine breed and is the only British pig that is entirely black. It is a hardy and docile pig, with Large Black sows known for having large litters.
The Large Black combined local black pig breeds from the West Country and the East of England; the Large Black Pig Society was formed in 1899. The breed was popular in the early 1900s and was exported to many areas of the world. Population numbers declined after the Second World War as farmers turned to breeds more suitable to intensive pig farming, and by the 1960s the breed was almost extinct. Numbers have slowly risen, but it is still considered vulnerable by the Rare Breeds Survival Trust, the American Livestock Breeds Conservancy, and Rare Breeds Canada.
History
The Large Black resulted from the amalgamation of black pigs from two geographically separate areas, Devon and Cornwall in the south-west of England, and Essex, Suffolk and Kent in the east. The pigs from eastern England, mainly Essex, were influenced by importations from China in the late 18th century, while those from Devon and Cornwall were probably more closely related to the pigs in mainland Europe, particularly France. The Devon pigs were originally selected for "the length of their bodies, ears, noses, tail and hair, the longer the better, without reference to quality or substance", but selective breeding brought improvements to the breed, and by 1850 the type was small-boned and thick-bodied, with good conformation and constitution. Alternative origins proposed for the black colour of the breed are black Guinea hogs imported from Africa (similar to the Guinea Hog of the US) or from Neapolitan pigs.
During the late 19th century, the Large Black grew in popularity. A breed association, the Large Black Pig Society, was formed in 1898 or 1899, in Ipswich, Suffolk. A trademark, consisting of the letters LBP within a shield, was registered in 1902.
The Herd Book of Large Black Pigs was first published in 1899. In it the large black pigs of Devon and Cornwall were combined under one name with the remnants of the smaller Black Essex, Black Suffolk or Small Black, and other black East Anglian breeds whose numbers had fallen below sustainable levels. There were considerable variations between the types in the two areas, but breeding stock was exchanged between them and by 1913 "general uniformity" had been achieved. The Large Black had by then spread throughout most of Britain, and had been exported to most of mainland Europe and to North and South America, Africa and Oceania. In 1919 a Large Black sow was Supreme Champion at Smithfield, and at the Royal Show that year 121 Large Blacks were entered, more than any other breed. Popularity of the breed peaked in the 1920s, however, and after World War II, population numbers declined as farmers began to favour pig breeds that would do well in intensive indoor farming. The breed association was merged with the National Pig Breeders Association (later the British Pig Association) in 1949.
In 1955 the Howitt report on the development of pig production in the United Kingdom was published. Its main conclusions were that UK pig farms were poorly placed to compete with European producers, that the diversity of local breeds in the UK was an obstacle to progress, and that British pig farmers should focus on three breeds only: the Welsh, the British Landrace, and the Large White. The report initiated a period of decline in all other British pig breeds, including the Large Black. By the time the Rare Breeds Survival Trust was founded 1973, numbers of all traditional pig breeds were dangerously low, and many of them were extinct. The Large Black was was placed on the Trust's endangered list.
The first American imports were in the 1920s, but the population dwindled to the point where imports were again necessary in 1985.
Description
The Large Black is a long, deep-bodied pig, well known for its hardiness and suitability for extensive farming. It is the only pig breed in Britain to be all black, and this trait helps protect the pig from sunburn in sunny climates. Temperamentally, the Large Black is a very docile breed which is easily contained by fencing, partly because its large, drooping ears obscure its vision.
The breed is also known for its long periods of fertility and strong maternal instincts. Sows give birth to a large litter of 8–10 piglets, but some sows have been known to have litters of up to 13 piglets. Also of note is the Large Black sow listed in the Guinness Book of Records for having produced 26 litters between 1940 and 1952 – the largest number of litters ever recorded for a pig. Boars weigh 700 to 800 pounds (320 to 360 kg) and sows around 600 to 700 pounds (270 to 320 kg), although obesity in sows sometimes results in cystic ovaries and a loss of fertility. The breed has become larger over the years; in the early 1900s, weights averaged 500 pounds (230 kg) for sows and larger for boars.
At its peak of popularity, the Large Black was used mainly for meat production, especially bacon. The meat from the Large Black is known for its quality and flavour, but for pork production it was often crossed with the Yorkshire and Middle White pigs, producing a commercially well-regarded and vigorous hybrid.
Conservation status
In 1954 there were 2195 Large Black pigs recorded, 269 licensed boars and 1926 registered sows, representing approximately 3.4% of the UK pig population of about 65,000. At the end of 2011 there were 421 Large Black pigs (86 boars and 335 sows) registered, a small increase over the 2010 figure of 405 (65 boars, 340 sows). The Large Black is the rarest historic pig breed in Britain, although numbers are slowly on the rise due to an increase in demand for meat from traditional pig breeds. In 2011 it was classified as "vulnerable" on the watchlist of the Rare Breeds Survival Trust, meaning that there are believed to be between 200 and 300 breeding females. The British Pig Association currently recognizes 6 boar lines and 24 sow lines within the breed.
In 2004 the Rare Breeds Trust of Australia listed the status of the Large Black as "critical", meaning that sow registrations in the Australian Pure Bred Pig Herd Book of the Australian Pig Breeders Association were fewer than 30 per year.
The American Livestock Breeds Conservancy estimated the Large Black population of the United States at 300 breeding hogs in 2008, and lists its status as "critical", which means that fewer than 200 animals are registered each year in the United States, and there are estimated to be fewer than 2,000 worldwide. Rare Breeds Canada identified the single remaining Canadian herd in 1997, and has since included the breed on its conservation watchlist as "endangered", with fewer than 500 of the animals in that country.
