How many days is the typical gestation period of a domestic pig?

The typical gestation period of a domestic pig is 114 days.

Pig breeders often remember this as “three months, three weeks and three days.” The period is measured from successful mating or artificial insemination until the sow gives birth to piglets. Individual pregnancies can vary slightly, so 114 days is a useful average rather than an absolute deadline.

Domestic pigs descend from Eurasian wild boar and have been raised for meat in many regions for thousands of years. A female pig is a sow, while a male is a boar; a newborn pig is a piglet. These terms are sometimes confused with cattle or sheep vocabulary.

Sows commonly give birth to litters containing several piglets, and the newborns are usually guided toward the udder soon after birth. The short, predictable pregnancy is one reason pig production can have several breeding cycles in a year.
