Ossabaw Island Hog

Ossabaw Island Hog is an American heritage pig breed descended from pigs left on Ossabaw Island, off the coast of Georgia, by Spanish explorers in the sixteenth century, where the population lived largely isolated on the island for centuries afterward. That isolation, combined with the island's limited and seasonally variable food supply, is believed to have shaped the breed's distinctive physiology, including an unusually efficient capacity to store fat, a trait that has drawn interest from researchers studying insulin resistance and metabolic disease in relation to diet. The hogs are small, dark-coated and hardy, with a build suited to foraging on the island's marsh and woodland vegetation rather than to rapid commercial growth. Because access to the island population has long been restricted, small breeding populations maintained off the island by heritage livestock keepers now sustain most of the registered Ossabaw Island Hog stock, and it remains a rare, closely conserved breed.
