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 breed's foraging ability make it particularly useful for extensive farming, while a poor candidate for intensive farming. The Large Black combined local black pig breeds from the West Country and the East of England. With the founding of a breed association in 1898 or 1899, variations between the types from the two areas decreased. The Large Black 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.〔(【引用サイトリンク】title=Large Black )〕 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,〔(【引用サイトリンク】 Pigs - Large Black )〕 and other black East Anglian breeds whose numbers had fallen below sustainable levels.〔〔, cited by: 〕 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Large Black pig」の詳細全文を読む スポンサード リンク
