Rambouillet is the “backbone” of the American Sheep Industry, forming the foundation of most western range flocks and raised throughout the United States. The Rambouillet descends entirely from the Spanish Merino. In fact, it is the French version of the Merino developed when Louis XVI imported 386 Spanish Merinos in 1786 for his estate at Rambouillet.
Though named for the town in France, the breed owes much of its development to Germany and the United States. The Rambouillet is a dual purpose sheep, producing a desirable carcass and good fine wool. Rambouillets are large sized, rugged and long-lived with a strong flocking instinct. Rambouillet ewes possess many desirable traits which have resulted in their inclusion in crossbreeding programs to improve lamb production.
