The Hampshire Breed has been developed in the United States of America and is now one of the World’s most important breeds.

The first hogs known as Herefords originated on the farm of R.U. Webber of La Plata, Missouri. Mr. Webber was said to have made his first crosses in about 1902, and these ultimately involved several breeds.

The Hezuo pig is from the Plateau region and are located in the Gannan Tibetan Autonomous Prefecture of Gansu Province, China.
