Most of the cows pictured above are native Indian breeds (I'm not sure about the one in Louieblades' post, it doesn't have the hump typical of Zebu cattle). There are basically two subspecies of cattle, the taurine (Bos primigenius taurus) originating from Europe and the zebu (Bos primigenius indicus) originating in India.....
