This breed of sheep grows hair instead of wool. The dominant color of the breed is white, due to selective breeding on mainland United States, however other acceptable colors are solid tan, brown, black or white with black or brown spots. Both ewes and rams are polled; rams have a large ruff on their neck. Ewes generally have twins, but it is also common for singles, triplets, and occasionally quadruplets. The breed is also well known for high parasite resistance.
They originated on the U.S. Virgin Islands on the Island of St. Croix. Believed to be descended from African breeds brought over on slave ships, the main populations exist in Africa and Southern Caribbean. They are also the foundation for more popular sheep breeds like the Katahdin and the Royal White.
