 Visayan warty pigs are also vulnerable to genetic contamination, as they readily hybridize with feral domestic pigs.The current conservation program for "S. c. negrinus" includes successful breeding programs at the Rotterdam Zoo for pigs of Negros origin, and at the San Diego Zoo for pigs of Panay origin.In addition to a few other conservation programs in the Philippines, the Crocolandia Foundation and the Negros Forests and Ecological Foundation both have this species in captivity.
