The Effect of Age of the Calf on the Availability of Nutrients in Vegetable Milk-Replacer Rations

Abstract

The study was designed to determine the influence of age on the ability of the calf to digest vegetable milk-replacer rations by determining the amounts of nitrogen, calcium, and phosphorus that were retained at four ages (10, 18, 26, and 34 days). Whole milk and evaporated milk were fed as standards of comparison. Male Holstein calves 2 to 4 days of age were assigned to the experiment at random. The milk replacers were not satisfactorily utilized until the calves were approximately 25 days of age. Editor.
