Wart Hogs are the only swine that all defecate together, like clockwork, between 4-14 times daily. Mating often occurs in May and June. Piglets nurse for several months and are completely weaned by 21 weeks of age. The young are temporarily driven away when the female is about to bear a new litter, but they may subsequently rejoin the family. Males separate from their mothers by the age of 15 months.
Females stay longer, sometimes permanently.
Wart Hogs are sexually mature at 18 to 24 months, but males usually do not mate until they are about four years old. A captive Wart Hog has lived for 18 years and 9 months.
