Developed from the Spanish Merino in France and Germany, the Rambouillet is the foundation of most Western U.S. range flocks. White-faced with wool on the legs, the Rambouillet is largest of the fine wool breeds, rugged, adaptable to a wide variety of arid range conditions, has a well-developed flocking instinct and is long lived. The breed also has an extended breeding season and produces a high-quality fine-wool fleece.
