Small White pig
The Small White or Small Yorkshire was a breed of domestic pig originating in the United Kingdom and which was common during the nineteenth century. It is now extinct, but its characteristics were used in producing the Middle White and other breeds.
History and characteristics
The Small White was developed in the early nineteenth century by cross-breeding the traditional Old Yorkshire, a large white pig, with imported Chinese pigs. This created a small animal with a pure white ground colour, pricked ears, the short, wide head of the Chinese breeds and their characteristic short upturned snout. In common with the Chinese breeds, it reached maturity early and rapidly put on fat. The Small White was further refined and "improved" during the period by agriculturalists such as Henry Reynolds-Moreton, 2nd Earl of Ducie amongst others.
Creation of the Middle White
The Small White proved a popular cross with both the Cumberland pig (now extinct) and the Large White, another Yorkshire breed. This was to lead 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 pig during the late nineteenth and early twentieth century: it retains the distinctive pricked ears and short snout of the Small White.
The popularity of the Middle White led to the decline of the Small White breed, and by the turn of the century it was nearly extinct; it finally became extinct in 1912. The breed likely survived in the United States where it was generally called the "Small Yorkshire"—for a few more years.
