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. 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.
When used as livestock, pigs are farmed primarily for the production of meat, called pork. A group of pigs is called a passel, a team, or a sounder. The animal’s bones, hide, and bristles are also used in products. Pigs, especially miniature breeds, are kept as pets.
