When a gilt is at least 6 months old, in heat and paired with a boar they have a chance to conceive piglets within a three day window. If the conception is a success the sow’s gestation period will last approximately 113 days until the new litter is born.
After the gestation period is over, sows will begin the birthing process. The expectant mother will make a nest where she can comfortably begin the farrowing process. When she is ready, she will birth the piglets one-by-one. For the first 6 to 8 weeks, a piglet consumes most of its nutrients from its mother’s milk.
