Abstract - An empirical study using five characteristics to distinguish the Visayan warty pigs from hybrids was conducted at the Silliman University captive breeding facility. The characteristics used were genotype, physical characteristics, behavior, fecundity, and carcass and meat characteristics. Hybridization of Visayan warty pig is seen as a threat to the genetic integrity of wild populations. Mitigation measures and
other recommendations to control hybridization include control of feral pigs and eradication of hybrids.
