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.[1] Pigs are omnivores and are very social and intelligent animals.[2] 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.
Domestic pigs come in different colours, shapes and sizes. They are usually pink, but little pigs kept as pets (pot-bellied pigs) are sometimes other colours. Pigs roll in mud to protect themselves from sunlight. Many people think that pigs are dirty and smell. In fact, they roll around in the mud to keep bugs and ticks away from their skin. This also helps to keep their skin moist and lower their body temperature on hot days. They are omnivores, which means that they eat both plants and animals.
Pigs are smart animals. They are even able to learn how to play video games.[4] Pigs are commonly used as working animals. They are used to hunt for truffles, pull carts and sniff out landmines.[4] Pig races exist.
