The domestic pig (Sus scrofa domesticus or Sus domesticus), often called swine or hog, is a large, even-toed ungulate; it is variously considered a subspecies of the wild boar, or a distinct species. Its head-plus-body-length ranges from 0.9 to 1.8 m (35 to 71 in), and the adult can weigh between 50 to 350 kg (110 to 770 lb). Compared to other artiodactyls, its head is relatively long, pointed, and free of warts. Even-toed ungulates are generally herbivorous, but the domestic pig is an omnivore, like its wild relative.
