Overview: A butcher. shows us the pig isn't the same pig as that of a few years ago. Nowadays a pig has an extra rib and a few extra nipples. Those are needed to carry and feed more piglets. A farmer tells us pigs now have more piglets than before. At a breeding company they explain us how we got the pig so far to give birth to more piglets and we visit a sperm station, of which the seed flies around the globe.
