breed once or twice per year in favorable conditions. Compared to other large mammals, wild hogs have a very short gestation period of about 114 days. Sows are sexually mature at 6-8 months of age and average 4-6 piglets per litter. Wild hogs can be found in social units called sounders.

How often can you breed a pig?

Mother pigs can usually breed twice a year and produce two healthy litters. Their pregnancy period is short — only about 3 months and 3 weeks — which helps them breed more often. Duroc pigs do have slightly larger litters, at around 10 to 15 piglets.

In extreme cases, where feasible, outright cannibalism will occur and the sow will eat the piglets. The development of this behaviour is often complex and difficult to stop and can cause significant losses.

How many days are pigs pregnant?

Fetal development occurs between attachment of fertilized embryos to the uterus, to the days right before parturition (birth). It is at this time, gestation, that piglets form and grow inside of the sow. Generally, the length of time a sow is pregnant, or gestating, is about 115 days, or 3 months, 3 weeks, and 3 days.

How many litters per year do pigs have?

Sows usually have 1 litter per year although 2 litters per year is possible, and young may be born at any time of the year. Litter size depends upon the age of the sow, nutritional intake, and time of year. Litters of feral hogs average 3 to 8 young, but have ranged up to 13. Wild boars usually breed at 18 months.
