Double-muscled Sheep?

There are several mutations that can increase an animal's muscle mass, decrease body fat and improve feed efficiency. This science has especially been successful in cattle like in Belgian Blue Cattle. Double-muscled cattle refers to breeds of cattle that carry a mutation which represses the myostatin protein, consequently augmenting muscle growth. Without the functional myostatin protein, muscle growth continues uncontrolled in the animal at the expense of other bodily functions, including reproduction and normal fat and bone deposition. Belgian Blue, Piedmontese and Parthenais are examples of double-muscled cattle.
