The Middle White is a breed of domestic pig native to the United Kingdom. It originated in Yorkshire roughly around the same time as the Large White. Its name comes from the fact that it was between the size of the Large White and the now-extinct Small White. It was fully recognized as a breed in 1884. The breed is known as a pork producer (rather than bacon or lard type pigs) and is best known for its sharply upturned snub nose. It is docile and often kept outdoors in grazing situations. Though its numbers have rebounded somewhat, the breed is listed as endangered by the Rare Breeds Survival Trust.
The Small White proved a popular cross with both the Cumberland pig (now extinct) and the Large White, another Yorkshire breed. This led to the creation of a new type after an incident at the 1852 Keighley Agricultural Show, when pigs belonging to Joseph Tuley, a weaver, were refused entry to the Large White class, as they were considered too small; they had been bred by crossing Large White sows with Small White boars. Tuley’s pigs were, however, considered good enough that a new breed was created, the Middle White, which went on to be one of the most popular breeds of the pig during the late 19th and early 20th centuries; it retains the distinctive pricked ears and short snout of the Small White.
