One of the Heritage Breeds - GOS or Old Spots was named after the county of Gloucestershire, England.
Considered a lard type hog the Old Spot has the traits of intelligence, docility and productivity. Boars and sows reach mature weights 500 pounds for sows and boars 600 pounds.
The GOS is unmistakably white and must have at least one clearly defined black spot.
The formation of the Gloucestershire Old Spot Breed Society was completed in 1913. Considered the oldest such breed, it appears from paintings the GOS has been around for some 2 to 3 centuries.
Gloucestershire Old Spot has been placed on the 'Critical List' by The Livestock Conservancy.
