The pig (Sus domesticus), often called swine, hog, or domestic pig when distinguishing from other members of the genus Sus, is an omnivorous, domesticated even-toed hoofed mammal. It is variously considered a subspecies of the Eurasian boar or a distinct species, but the American Society of Mammalogists considers it the latter.[3] The pig's head-plus-body length ranges from 0.9 to 1.8 m (3 to 6 ft), and adult pigs typically weigh between 50 and 350 kg (110 and 770 lb), with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed. Compared to other artiodactyls, a pig's head is relatively long and pointed. Most even-toed ungulates are herbivorous, but pigs are omnivores, like their wild relative. Pigs grunt and make snorting sounds.
