Anatomy of a Pregnant Pig 🐖

A pig’s gestation period is about 114 days
(3 months, 3 weeks, and 3 days).

During this time, the sow’s body goes through major internal changes to support the developing piglets.

Inside the pregnant sow:
1⃣ The uterus expands to carry multiple piglets
2⃣ Internal organs shift to make space
3⃣ Nutrients from feed are shared between the sow and the unborn piglets

This is why gestation feeding and management matters so much.

Poor nutrition during pregnancy doesn’t just weaken the sow, it leads to:
• small or weak piglets
• low birth weights
• higher piglet mortality after birth

Many piglet problems don’t start at farrowing.
They start inside the womb.
