Welsh

Pig

The Welsh is a breed of domestic pig native to Wales. It is a large white breed known for its hardiness in outdoor (extensive) farming and its long, pear-shaped body. First mentioned in the 1870s, the breed is currently the third most common sire in the U.K. after the Large White and British Landrace. The Welsh pig is not exported to many countries around the world at all despite the fact that they can produce substantially good bacon.
