Effect of energy and undegraded intake protein on growth and feed efficiency of growing Holstein heifers

Two trials using 32 heifers each evaluated response to undegraded intake protein (UIP) (30 or SO% CP), energy (supporting .S9 or .91 kg ADG), and source of UIP (blood meal or combination protein supplement).
