The Baudin Pig is a landrace of domestic pig, found on Kangaroo Island, South Australia. The first pigs were released on the island in the 1800s. Over 200 years the pigs developed in isolation from other pig species. All the wild Baudin pigs on the island were killed in the Kangaroo Island bushfires in 2007. Four Baudin pigs survived at a farm for rare breeds on the island.
The pig is named after Nicolas Baudin, a French explorer who is claimed to have brought them to Kangaroo Island. Westran Pigs are an inbred form of the breed and crossed with the large white pig. These are used in medical research, particularly for xenotransplantation.
