Pigs are omnivorous animals, which means that they eat both plants and meat. In the wild, pigs mostly eat insects, fruits, and roots. However, on modern pig farms, pigs are typically fed a diet of corn and soybeans. Pigs will also eat other animals if they can find them. For example, pigs will eat small rodents, reptiles, and amphibians.
Pigs have an interesting digestive system. Their stomachs are very acidic, which aids in the digestion of their food. Pigs also have a caecum and a large colon, which help them to digest the foods they eat.
Pigs have 42 teeth, which are used for chewing and tearing their food apart before it is digested. Pigs have incisors for biting and canine teeth that develop into tusks. Pigs are not ruminants and do not chew cud. See MSD Veterinary Manual and Penn State Extension.
