Origins and History –
The Roya Bilbilitana sheep is a sheep breed in danger of extinction whose name derives from the reddish brown color of the fleece and takes its name from “BÃlbilis”, the pre-Roman and then Roman city of the Iberian peninsula located on the hill of Bámbola, on the banks of the river Jalón, in the Huérmeda neighborhood, Calatayud (Zaragoza).
This breed belongs to the entrefine strain and is characterized by the color of its coat, which is black at the birth of the lambs but then progressively acquires a shade between earthy and reddish.
There is no clear coincidence regarding its possible origins, as different hypotheses based on different writers are considered.
The Official Catalog of Livestock Breeds of Spain includes it in the list of threatened native breeds.
In fact, this breed came to the brink of extinction in the 20th century due, among other factors, to the abandonment of the rural world by the population, the introduction of other breeds which presumably gave greater economic performance and the crossing of herds with white breeds.
