Abstract
Holstein calves (21) were divided into 3 groups of 7 calves each and placed on the following milk-replacer rations; basal, basal plus 5% dried whey, and basal plus 3.5% lactose at 4 days of age. Calves in the 3 groups consumed 54.9, 51.9, and 50.7 lb. of whole milk, respectively. Average daily gains on the 3 rations were 0.87, 0.92, and 0.87 lb., respectively. Differences were not statistically significant. The calves receiving the whey ration had more costive feces and smoother coat and were more alert. Lactose appeared to have no benefit under the conditions of this experiment.
