A Proposed Method for Removing Sources of Error in Beef Cattle Feeding Experiments1

Abstract

Experimental evidence is presented for the development of a method for conducting experiments with beef cattle which removes much of the variation caused by composition of the body and weight of the gastrointestinal tract contents. The carcass as corrected to equal caloric content adjusted in an analysis of covariance to equal initial weight was shown to be a more reliable measure of animal performance than weight gain or weight gain in combination with dressing percent and carcass grade. From a review of the evidence presented,the following seems to be the most desirable method for obtaining the maximum amount of reliable information from beef cattle feeding trials: Copyright © . .
