The Gloucestershire Old Spots is a heritage [[Pigs|pig]] breed originating in the Gloucestershire region of western England. The breed is white with distinctive black spots and is notable for its extreme hardiness, ability to thrive on forage, and the high quality of its pork. Gloucestershire Old Spots are among the most popular heritage pig breeds for pasture-based production and are classified as a threatened breed by the Livestock Conservancy.
The Gloucestershire Old Spots was developed in the Berkeley Vale of Gloucestershire, where it was known as the "Berkeley" or "Gloucestershire" pig. The breed's ancestry includes the original spotted pigs of the West Country, with possible crosses to the now-extinct Long White pig and the Lincolnshire Curly Coat. The breed was kept by small farmers in the region as a dual-purpose animal for both meat and lard.
The breed was first exhibited at the Royal Agricultural Show in 1885 and was standardized in the early 20th century. The Gloucestershire Old Spots Pig Breeders' Association was formed in 1913. The breed's population declined dramatically after World War II, as British agriculture shifted toward leaner, faster-growing breeds suited to confinement production. By the 1970s, the breed was on the verge of extinction, with fewer than 50 registered breeding females. Conservation programs by the Rare Breeds Survival Trust in the UK have since restored the population.
Gloucestershire Old Spots are large, long-bodied pigs with white skin and clearly defined black spots. The skin should be white with black patches; any other color is not accepted in the breed standard. The ears are large and flop forward over the eyes, a trait known as the "old-fashioned" ear carriage. Mature sows weigh 500 to 700 pounds (225 to 315 kilograms), and boars weigh 600 to 800 pounds (270 to 360 kilograms).
The breed is exceptionally docile and is known as the "orchard pig" for its historical role in eating fallen fruit in Gloucestershire apple orchards. Gloucestershire Old Spots are outstanding foragers and can derive a significant portion of their diet from pasture, roots, and forage. Sows are prolific with excellent maternal instincts.
Gloucestershire Old Spots are raised primarily for pasture-based pork production. The meat is dark, well-marbled, and highly regarded by chefs for its flavor and texture. The breed's foraging ability makes it economical on homesteads with adequate pasture or orchard area. Their calm nature reduces the need for specialized handling facilities.
The breed's large frame and moderate growth rate require a longer finishing period than commercial breeds, typically 8 to 10 months to reach market weight. Gloucestershire Old Spots are best suited to homesteads with adequate space for rotational grazing.
