The Large Black pigs (also known as English Large Black ) are also on the American Livestock Breeds
Conservancy 's list of critically endangered breeds of swine. They are a very old breed of English pig. The dark
skin of these hogs makes them impervious to sunburn and also helps them obtain warmth in cold winter climates. Over time they
have become very efficient foragers and grazers and are able to make weight gains on grass whereas other modern breeds of
pigs need high quantities of grain to put on weight.
