Abstract
One hundred and thirty-seven cow-calf pairs on pasture in southeastern Alberta, were randomly allocated to one of two treatments no supplement (NOS) or 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 higher (P < 0.01) in calves fed HPS (306.0 kg and 1.49 kg d−1) compared with NOS (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 gain at weaning was $9.60. Key words: Creep supplement, pasture, growth, beef cattle
