Abstract
One hundred and thirty-seven cow-calf pairs on pasture in southeastern Albe rta, were randomly allocated to one of two treatments no supplement (NOS) o r a high by-pass protein (70% of CP) creep supplement (HPS) at an intake of 1.5 kg head(-1) d(-1). Calf weaning weights and pre-weaning ADG were highe r (P < 0.01) in calves fed HPS (306.0 kg and 1.49 kg d(-1)) compared with N OS (298.2 kg and 1.41 kg d(-1)), respectively. However, it was uneconomical to feed this high by-pass creep as the feed cost of a kg of additional gai n at weaning was $9.60.
