The Gloucestershire Old Spots (also "Gloucester, Gloucester Old Spot, Gloucestershire Old Spot" or simply "Old Spots") is an English breed of pig which is predominantly white with black spots. It is named after the county of Gloucestershire. The Gloucestershire Old Spots pig is known for its docility, intelligence, prolificity, and hardiness. Boars reach a mature weight of 600 lb (272 kg) and sows 500 lb (227 kg). The pigs are white with clearly defined black (not blue) spots. There must be at least one spot on the body to be accepted in the registry. The breed's maternal skills enable it to raise large litters of piglets on pasture. Its disposition and self‑sufficiency should make it attractive for farmers raising pasture pigs and those who want to add pigs to diversified operations.
