However, some of the hogs have a white blaze on their face which indicates the hybridization that has occurred. Although the maximum weight for a wild hog is 300 pounds, most male hogs in the Smokies weigh about 125 pounds. Females weigh slightly less. Both sexes have 44 teeth including a well developed set of canine teeth. Coat color varies from gray to black, and most piglets have longitudinal stripes until they are about four months old.
Hogs have poor eyesight, but a keep sense of smell and hearing.
Wild hog piglets weigh about two pounds at birth. After three or four months, the piglets are weaned and independent of the sow. Family groups usually break up once the young reach sexual maturity, which is usually within a year of birth for both males and females. During years of mast failure, reproduction ceases, and even adults may die of starvation. Because of the abundance of habitat and food in the Smokies, the average hog has a life expectancy of about eight years.
