Body Composition of Mature Beef Cows^{1, 2,}

Texas A&M University, College Station 77843

Abstract

Seventy-four mature Hereford cows were slaughtered at three intervals during a 39-week study to determine changes in body composition which occurred concomitantly with changes in body weight. Percent fat, protein and moisture in the empty body and soft tissues of the chuck, loin, rib and round were not altered (P < .05) by either time or treatment variables. Liver glycogen content also remained unchanged. Calcium in bone ash exhibited a significant time x treatment interaction (P < .05). Changes in total empty body energy (EBE) were due mainly to significant changes in empty body weight with a maximum observed change of 189,750 kcal per cow. This change in EBE represented approximately one-fourth of the total EBE of a typical cow used in the study.
