Feed represents the largest component of the total cost of heifer production, and it clearly represents the major way to control heifer costs. Diet type and the amount fed can be large factors that affect feed efficiency and are the major aspects that we use in precision-feeding heifers. Ration digestibility is also obviously important. The more digestible the feedstuffs used in the ration, the more efficient the heifer will be.
