A pig’s physical make-up does not lend itself to using great quantities of pasture or roughage like sheep and cattle. But a 400-pound sow can handle relatively large amounts. Good forage can also provide quality protein and certain vitamins and can reduce total feed requirements.
What do pigs like to graze on?
Pigs do best on pastures that are high in protein. This means having a good mixture of grass and legumes. Past research has been done mostly on grazing alfalfa. If you have the right field and conditions, this might be your best option.
What wild plants do pigs eat?
Some of the many plants these wild pigs eat are acorns, forbs, grass, tubers, roots, bulbs and fungi. Acorns are a particular favorite for feral hogs. They also like eating a lot of herbaceous vegetation, including water hyssop (Bacopa monnieri).
