The pig breed known for a black body, white shoulder band, and English origin is the Saddleback.
The British Saddleback was developed in England by combining traits from the Essex and Wessex Saddleback breeds. Its defining appearance is a mostly black body crossed by a broad white band around the shoulders and forelegs, giving the pig a saddle-like marking.
The breed is valued as a hardy outdoor pig and is associated with traditional British systems of pig keeping. It has good mothering ability and is used for pork production. Breed descriptions can vary slightly in wording, but the black-and-white saddle pattern is the key identifying feature.
The name can cause confusion because “saddleback” is also used descriptively for animals with a banded back. The Berkshire, another famous English pig breed, is generally black with white points on the face, legs, and tail rather than a complete shoulder band. The Tamworth is characteristically reddish-gold.
