San Diego and Cincinnati Zoos each imported 1.2 Bornean Bearded Pigs in 1992. The first birth occured in 1997 at the San Diego Zoo and all of the wild caught pigs have contributed to the program except for one female who died in 2003. These suids can be found in San Diego, Brownsville, Lowry Park, Philadelphia, Shadow Nursery, Omaha, and at a few other private holders.
The Visyan Warty Pigs are a well inbred population. San Diego imported 3.5 captive bred pigs in 2001/2002 from a wildlife center in the Philippines. Two males died in quarantine, leaving but one male (whose father and grandfather are the same male) to sire most of the warty pigs in North America (his sons, etc. sired the others). Visyan Warty Pigs can be found at San Diego, Capron Park Zoo, Lowry Park Zoo, Oregon Zoo, Los Angeles, Minnesota, and St Louis. Current Jan. 2008.
