Two experiments were conducted with 32 dairy calves to study the value of pasture. In the first experiment, 22 Holstein calves were divided into three groups : barn-fed, pasture, and pasture plus hay free choice. The average daily gains were 0.97, 1.14, and 1.10 lb., respectively, to 60 days of age and 1.46, 1.67, and 1.70 lb., respectively, from 60 to 116 days of age. The differences in average daily gain were not statistically significant. The pasture group consumed 98.4 lb. less grain and the pasture-hay group 107.0 lb. less grain than the barn-fed group.
