A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar, along with other species; related creatures outside the genus include the peccary, the babirusa, and the warthog. Pigs, like all suids, are native to the Eurasian and African continents. Juvenile pigs are known as piglets.Pigs are highly social and intelligent animals.
Pigs are omnivores and can consume a wide range of food, similar to humans.Pigs can harbour a range of parasites and diseases that can be transmitted to humans. Because of the similarities between pigs and humans, pigs are used for human medical research.
The wild pig (Sus scrofa) can take advantage of any forage resources. Therefore, it can live in virtually any productive habitat that can provide enough water to sustain large mammals such as pigs. If there is increased foraging of wild pigs in certain areas, it can cause a nutritional shortage which can cause the pig population to decrease. If the nutritional state returns to normal, the pig population will most likely rise due to the pigs' naturally increased reproduction rate.
