Domestic Pig


Did You Know?

  • Pigs are believed to have been domesticated at least 9,000 years ago. Domesticated pigs are a subspecies of wild boar.
  • There are approximately 60 million pigs at farms at any given time just in the United States.
  • Most livestock were first used by nomadic peoples, but pigs were indicative of settled farming communities because they are hard to herd and move for long distances.
