The Middle White is a breed of pig originated in the Yorkshire area at about the same time and from the same general stock as the Large White and Small White breeds. Mainly, it was a selection for the intermediate size that caused it to be classified as a separate breed.
The white-colored swine are well balanced and meaty. They are usually bred straight in England and have not captured much of a share of the commercial market. The breed is found scattered over England today, but has been generally declining in popularity. When crossed with the Large White, they have been successfully incorporated into commercial operations. Despite their smaller size, the sows have been found to rear an average of 8.15 pigs per litter. They are good mothers and are known for their quiet nature.
