Systems adopted include suckler cows, where the calf is reared by its mother, and the buying in, and growing on, of young beef cattle. Some of these are crossbred calves, a by-product of the dairy industry, where the dairy cow is put to a Charolais, Limousin, Angus, Hereford or similar beef bull. Many of these "stores" are later sold to other parts of the United Kingdom for fattening.
