- Calculate: The calculator will add 114 days (the typical pregnancy length for pigs) and give you an expected farrowing date.
What to Know About Pig Gestation
On average, sows are pregnant for 114 days—about 3 months, 3 weeks, and 3 days. This timing holds for most breeds, so it’s a handy rule to remember. With this tool, you can plan things like setting up a clean farrowing space and having any supplies ready.
Interesting Stats on Sows and Piglets
- Gestation Period: The average gestation is 114 days, but some sows may vary by a day or two.
- Litter Size: Most sows give birth to around 10-12 piglets at a time.
- Piglet Growth: Newborn piglets usually double their birth weight in the first week, so early care is key!
Signs Your Sow is Close to Farrowing
Keep an eye out for these signals as her due date nears:
- Nesting Behavior: Sows often start making a nest about a day before farrowing.
- Restlessness: Around 24 hours before birth, she may seem more active or unsettled.
- Milk Production: A sign that birth is close, you might see milk in her teats about 12 hours before.
How soon after birth can my sow get pregnant again?
Sows can come back into heat about 5-7 days after weaning their piglets, but it’s often recommended to wait a full cycle to ensure she’s fully recovered before breeding again.
What if my sow goes past the estimated due date?
While it’s common for some sows to give birth a day or two after the expected date, if your sow goes more than a week past the due date, consider consulting a veterinarian to check on her health and pregnancy.
