History and Development

In 1761, the Yorkshire breed was first developed in the Yorkshire region of England. In 1830, the initial specimens of the Yorkshires were first introduced to the USA, especially in Ohio, from Canada and England. However, it was the slow growth rate of these pigs that restrained it from being popular until the latter half of the 1940s.

Later, the breed started to develop rapidly by selective breeding. Presently, this swine is found in almost all the American states. The modern population is large, with a stout and muscular built, having a high proportion of lean meat.

From the time of its popularity, the data of the pet Yorkshire swines have been diligently maintained, including backfat formation, growth, sow productivity, etc. This is the largest source of documented records of any livestock in the whole world. The highest populations of these pigs are concentrated in Illinois, Ohio, Iowa, Indiana, and Nebraska.

On April 1, 1893, the American Yorkshire Club was organized for the first time in Minneapolis, Minnesota. Initially a stock company, it was later reorganized in 1948 and became a membership organization.
