Origins and History –
The Rasa Aragonesa sheep breed originates from the autonomous region of the same name. This breed derives from the evolution of the primitive sheep breed Ovis Aries Ligeriensis, which was introduced from central Europe on the peninsula and settled in the Ebro valley, thus adapting to the conditions of the region.
The term Rasa refers to the short length of its fleece, while Aragonesa obviously refers to the area in which it is mostly found, that is, in the Autonomous Community of Aragon.
The breeding of this breed and the keeping of its registers is regulated by the Spanish government with a resolution of 28 January 2020, of the General Directorate of Agricultural Productions and Markets.
