With around 2 billion individuals alive at any time, the domesticated pig is one of the most numerous large
mammals on the planet.
The ancestor of the domesticated pig is the wild boar, which is one of the most numerous and widespread large
mammals. Its many subspecies are native to all but the harshest climes of continental Eurasia and its islands, from
Ireland and India to Japan and north to Siberia. Although it has been exterminated in some areas, its numbers are
stable or even increasing rapidly, in most of its native range.
Long isolated from other pigs on the many islands of Indonesia, Malaysia, and the Philippines, pigs have evolved
into many different species, including wild boar, bearded pigs, and warty pigs. Humans have introduced pigs into
Australia, North and South America, and numerous islands, either accidentally as escaped domestic pigs which
have gone feral, or as wild boar. These have typically adapted well, and are increasing in number and broadening
their range outside human control
Pigs are omnivores, which means that they consume both plants and animals. In the wild, they are foraging
animals, primarily eating leaves, grasses, roots, fruits and flowers. In confinement pigs are fed mostly corn and
soybean meal with a mixture of vitamins and minerals added to the diet
