[QUOTE="ANAZAZI, post: 1343951, member: 7541"] There is a difference. It is a very important difference. A crossbred calf will exibit hybrid vigour, generally this vill give it more growth. A crossbred cow will also exibit hybrid vigour, it will give her better fertility, longevity and more milk, she will give more growth to her calf than a purebred cow can. A calf benefits from being crossbred. It benefits from having a crossbred mother. IT DOES HOWEVER NOT BENEFIT FROM A CROSSBRED FATHER, it does not matter for hybrid vigour if the bull is crossbred or not. There is a way of benefitting fully by crossing three breeds: two maternal breeds are crossed to produce the cow and a third breed, a terminal, is crossed on that cow for feeder calves. If you have to choose between full hybrid vigour in the cow or in the calf, it is more important to have it in the cow, with a calf that gets full benefit of a crossbred mother and half the benefit from being crossbred himself (hybrid vigour is halved by the fact that his father has the same breed as one of the mothers parents). Put a crossbred bull on a purebred cow of a third breed, the calf gets the same hybrid vigour it would have gotten with a purebred sire on a purebred cow of a different breed. Put a crossbred bull on a purebred cow of the same breed as one of his parents the calf gets half of full hybrid vigour, with a mother that has no hybrid vigour. Do you see the difference? [/QUOTE]
