Feral swine reproduction, like domestic swine, is three months, three weeks and three days. One sow may have between five and eight piglets and, if she doesn’t get bred, comes into heat every 18 to 24 days. “They have many chances to breed, so their potential to put young on the ground is high,” says Dr. John Tomecek, assistant professor and Extension wildlife specialist, Stiles Farm, Thrall, Texas. "Not all of them survive but many of them do and within six to 12 months all of those young are ready to have their piglets.”
As the hog population continues to grow in Texas, Tomecek says just to keep numbers where they are, two-thirds of the living pigs would need to be killed annually. “We estimate we only kill about one-third of the pigs.”
