Pigs can be used for multiple reasons such as meat, leather, bristles for certain brushes, and muliple medical products. Over the years pigs have become known as gross and/or stupid, but recent intelligence tests have shown that not only are they intelligent but that (domesticated) pigs are more intelligent than all domestic animals even smarter than dogs. Pigs are distantly related to hippopotammuses. All pigs are omnivores meaning that they eat plants and small amimals. Most domestic pigs however are feed diets of corn, grain, root, and tuber crops, dairy by-products, and commercial feeds. Male pigs are called boars, castrated boars are called barrows. Afemale pig is a gilt untill she has babies then she is called a sow. There have been at least 377 breeds of pigs raised. Some of the main types of domesetic pigs are Landrace, Berkshire, Chester White, Duroc, Hampshire, and a Yorkshire.

There have been two major ways that pigs have been raised over the years. One way is pen rearing, the keeping of pigs encosed in pens. The second way of raising pigs is where the pig is allowed to roam free, where it can scavenge for food and root wherever it wishes. The second method is primarily practiced in Third World countries.
