GLOUCESTERSHIRE OLD SPOTS

“Gloucestershire (pronounced gloster-sheer) Old Spots (GOS), known for their distinctive white coat with black spots, were developed in the Vale of Berkeley in Gloucestershire, England. Recognized as the oldest pedigree spotted pig in the world, the GOS was once popular for small family farms, where they were raised on dairy by-products (such as whey) and orchard “drop fruit,” giving these pigs the nicknames “cottage pig” and “orchard pig.” British folklore claimed the large black spots were bruises caused by apples falling onto them as they foraged the orchard floors for food.”
