Some producers claim that heavy bush for shelter from the wind and the use of round straw bales for bedding is all that is required for providing shelter for mature wild boar in winter. Piglets, feeders, and replacement gilts need protection from cold, drafts, winds, sun, rain and snow. Cattle shed and other semi-enclosed shelters along with lots of bedding will provide adequate protection. Fencing is required which will prevent burrowing, confine piglets, keep out predators, and separate mature males from females. Handling facilities may be desirable for moving, separating and loading animals.
Most operators make maximum use of pasture as a feed source.
Supplemental hay and grain are often fed. There is a lack of nutritional research on wild boar. Because of their lower productivity and slower growth rate, the daily requirements of wild boars will be less than for domestic hogs. During winter, when pasture is not available, commercial hog mineral premixes may be used to supplement the wild boar's vitamin, mineral and salt requirements. Sows during gestation and nursing require more energy.
