The ratio of male to female feral pig births is 1:1. Male feral hogs breed at 18 months and the female can breed at six months. A female can breed every six months. Litters are from 3 to 12 pigs. Theoretically, one wild feral sow can produce 24 pigs per year. Her first litter female pigs (6 females) will have pigs when she has her second litter. She has 24 total pigs, and 6 of her pigs have 12 pigs each (72). In one year, each sow can be responsible for 96 pigs. Year two is an explosion of pigs! Does this make sense yet?
