Pig

The pig (Sus domesticus), often called swine (pl.: swine), hog, or domestic pig when distinguishing from other members of the genus Sus, is an omnivorous, domesticated, even-toed, hoofed mammal. It is variously considered a subspecies of Sus scrofa (the wild boar or Eurasian boar) or a distinct species. Pigs were domesticated in the Neolithic, both in East Asia and in the Near East. When these arrived in Europe, they extensively interbred with wild boar but retained their domesticated features.

Pigs are farmed primarily for meat, called pork. The animal's skin or hide is used for leather. China is the world's largest pig producer, followed by the European Union and then the United States. Around 1.5 billion pigs are raised each year, producing some 120 million tonnes of meat.

Pigs have featured in human culture since Neolithic times, appearing in art and literature for children and adults.
