The Betizu feral cattle breed is considered as one of the most endangered and ancient in Europe. It is native to the Basque Country (Euskadi). A small number survives in Bizkaia, Gipuzkoa (Basque Autonomous Community), the Navarre and the Atlantic Pyrenees Department of France (Lapurdi). This paper describes the origin, habitat, zootechnical characteristics, aptitudes and attributes of this breed. At present, conservation projects have been initiated in order to preserve the remaining populations.
