Female pot-bellied pigs are known as gilts if they’ve never been pregnant, and sows if they have produced at least one litter. Gilts are usually spayed at a young age to prevent undesirable traits such as odor, aggressiveness, mounting of other pets and people, and urine-marking. Spaying prevents diseases such as uterine tumors which are common in older intact gilts and sows. We recommend that a spay is performed when a gilt is between 4 and 6 months of age. If an intact gilt is already showing these behaviors, she may never lose these traits even once she has been spayed
