Ossabaw Island, located off the coast of Georgia, is home to the eponymous rare breed Ossabaw Island Pig which descends from Spanish pigs brought by explorers over 400 years ago. With approximately 2,000 pigs remaining on the island, and fewer than 200 in other programs, these pigs are listed as "critical" by the American Livestock Breeds Conservancy.

The Large Black Breed is also listed as "critical" by the American Livestock Breeds Conservancy. Identified as a breed in 1899, the Large Black is well suited to outdoor production due to its hardiness and coat color, and has a fine-grained tender meat.
