Domestic Pig - Behaviour

Behaviour

The behaviour of domestic pigs is more like that of dogs and humans, rather than cattle or sheep; in many ways, their behaviour appears to be intermediate between that of carnivores and the more highly evolved artiodactyls. Domestic pigs seek out the company of each other and often huddle to maintain physical contact, although they do not naturally form large herds.

If conditions permit, domesticated pigs feed continuously for many hours and then sleep for many hours, in contrast to ruminants which tend to feed for a short time and then sleep for a short time. Pigs are omnivores and are highly versatile in their feeding behaviour. They can survive well by scavenging on the same types of foods that humans and dogs can live on. In the wild, they are foraging animals, primarily eating leaves, grasses, roots, fruits and flowers. Domestic pigs are intelligent and can be trained to perform numerous tasks and tricks. Recently, they have enjoyed a measure of popularity as house pets, particularly the dwarf breeds.

Very rarely, either naturally as a result of unusually aggressive behavior, or perhaps as the result of a pathological process which alters their disposition, domestic farm-based pigs have become aggressive and injured and eaten their handlers.
