Suffolk sheep, relatively large breed, developed in England, well-known for its high quality meat. Considered to be a recent introduction to the United States, the breed has many desirable qualities and is becoming widely accepted there. Suffolks have bare heads, black faces, and bare black legs but no horns. They breed aggressively and have upstanding carriage, an active nature, the capacity for rapid growth, and a good mutton build; they are, however, relatively light fleece producers. Suffolk rams are widely used with ewes of other breeds to produce crossbred lambs for slaughter.
