The Cheviot Mule is the name for a crossbred sheep derived from a Cheviot Ewe crossed with the Bluefaced Leicester Ram.
The Cheviot Mule ewe is then usually crossed with a meat-type ram to produce market lambs. As the North American Mule Sheep Society explains, "The Mule ewe lambs are either retained for the next step of the system, or sold off the farm in the fall at the livestock markets by the thousands. They are purchased to make-up large commercial flocks for the UK’s “prime” lamb production. In the final tier of the scheme the Mule ewes are bred to terminal sires, renowned for their heavy carcass genetics; the preferred ones being either a “British” Suffolk or the Texel. This third step in the system produces a carcass lamb that easily reaches market weights off milk and grass."
