What happens if brother and sister pigs mate?
A mating between a brother and sister from unrelated parents would result in an inbreeding coefficient of 50%. A mother/son (or vice versa) or father/daughter (or vice versa) mating would result in a breeding coefficient of 25% assuming that there were no other related matings in the preceding generations.

Because of these problems, it’s important to keep a close eye on sows that are about to farrow (give birth).

Monitoring sows electronically, or simply camping out in the barn, old-school, can help reduce piglet mortality.
How long after pigs are weaned can you re-breed?
