It is the ancestor of domestic cattle.ecause some cattle breeds have been changed more than other breeds, certain breeds (all belonging to the so-called landraces) bear a greater resemblance to the aurochs. These breeds are not very productive from the economical point of view, as they do not give as much milk or meat as others.
