- Feral Swine in Michigan - A Growing Problem Like other Midwestern states, Michigan is experiencing a growing problem with feral or wild swine. Thirty years ago, there were no feral swine sightings reported in Michigan. By the end of 2011, more than 340 feral swine had been spotted in 72 of Michigan's 83 counties, and 286 have been reported killed. A sow can have two litters a year of four to six piglets. Based on their prolific breeding practices, it is estimated that feral swine in Michigan currently could number between 1,000 and 3,000.
Feral swine are a problem for two main reasons - they can host many parasites and diseases that threaten humans, domestic livestock and wildlife; and they can cause extensive damage to forests, agricultural lands and Michigan's water resources.
