Minimum protein requirements for the growth of dairy heifers

Abstract

In order to reduce the feed cost as much as possible, it is of considerable importance to know the required amount of protein necessary to develop the heifer normally. To best arrive at a protein standard for dairy heifers it would seem advisable to determine the minimum amount of this constituent necessary to promote their normal growth. With the object of determining such a figure, the Missouri Experiment Station started an experiment in August, 1913. The results of this experiment to date are given herein. It has not been the intention to show the relative value of different rations. The practical value of the experiment will lie in the results obtained rather than in the methods used.
