QUESTION
how long does a pig stay pregnant & when will she be ready to have another litter ?


ANSWER

The gestation (pregnancy) period of the female pig is 114 days. She will be ready to be bred another time around 5-7 days after her pigs are weaned (removed from nursing). Thus if you wean the litter of pigs at 21 days of age she will come into estrus (heat) around 26-28 days after farrowing (giving birth).

Sincerely,

Gilbert Hollis Extension Swine Specialist Department of Animal Sciences University of Illinois
