Pig Production: When Can Pigs Get Pregnant?

Pigs are interesting animals with their own way of growing up and having babies. If you're wondering when pigs can get pregnant, it's good to know a bit about how they develop.

Pigs become adults and are ready to have babies at different times depending on their size and type. Usually, girl pigs (called sows) can start having babies when they are about five to six months old. But this can change depending on the kind of pig they are.

When a sow is ready to have babies, it's because of something called an estrus cycle. This happens about every 21 days. During this time, she can get pregnant if a boy pig (a boar) mates with her. Farmers keep an eye on this cycle to know the best time for pigs to have babies.

After a sow gets pregnant, she carries the babies for about three months, three weeks, and three days. That's about 114 days. During this time, she needs good food and care to stay healthy and make sure her babies grow well.

Once you know and understand when your pigs can get pregnant, it will help  you plan how they take care of them.

In short, pigs can start having babies when they're about five to six months old, but this can change based on the kind of pig. Keeping track of their cycles and taking good care of them during pregnancy is important for farmers to have healthy pigs.
