History shows us that one European species of hog bred with a Southeastern Asian hog and were domesticated in China some 9000 years ago. Europeans continued the breeding process until Christopher Columbus introduced the domesticated animal into the States in 1493. The American pig is a heavy animal with a large, round, stout body. They have short legs, thick skins and short, coarse, bristles of hair sporadically scattered about their body. Hooves have two digits that are functional, and two that are not.
Snouts are short and pliable.
Tails are small when cut and long, when not cut. Contrary to their appearance, pigs are quick thinking, fast moving animals. There are three types of domesticated American pigs, categorized by size and weight. The large, lard pig carries a thick layer of fat and weighs a minimum of 220 pounds. Bacon pigs are 150 pounds.
