Wild pigs have a typical domestic pig shape with a long, blunt snout, small eyes, and large ears. They are more long-legged and appear more powerful than domestic pigs. They have a very coarse coat with thick, short hairs. They are usually brown but can appear rusty-red or black. Depending on the sub-species, both males and females may have tusks, although these are almost always longer in males. Wild Pigs prefer the cover of dense brush or marsh vegetation. Wild pigs are omnivores. Types of food vary greatly depending on the location and time of year, but plants make up about 85% of their diet. Acorns or other mast, when available, make up a good portion of the diet. The most common complaint of damage caused by wild pigs is rooting, sometimes called grubbing. The act of rooting destroys pasture, crops, and native plants, and can cause soil erosion. Wild pigs are hosts to several diseases that may threaten the health of wildlife, livestock, and humans. Cholera, swine brucellosis, trichinosis, bovine tuberculosis, foot and mouth disease, African swine fever, and pseudorabies all may be transmitted to livestock from wild pigs.
