Pigs or domestic pigs are mammals in the genus Sus. Pigs are in the Suidae family of even-toed ungulates.
Related, but outside the genus, are the babirusa and the warthog. Pigs, like all suids, are native to the Old World. Baby pigs are called piglets or pups. Pigs are omnivores and are very social and intelligent animals. Its ancestor is the common Eurasian wild boar (Sus scrofa).
The pig has stout, barrel-shaped bodies, with short legs.
The flesh of domestic pigs is eaten as food and is called pork. The Jewish and Muslim religions, and some Christian denominations, believe eating pork is wrong. Pig farmers take care that the animals do not get diseases or parasites which might harm humans.
