various body measurements of the steers were taken on foot before slaughter. These body measurements were taken to determine whether there exists any association between the measures themselves and between them and certain performance characters. These relationships may be of practical value to a breeder in the selection of his stock. This paper is based on five measurements--height at withers, height to floor of chest, heart girth, width at shoulders, length of body; and their relationship to average daily gain, efficiency of feed utilization, and the age of the steers when they reach 900-pounds live weight. Associations of birth weight, age and weight at weaning with these measurements and rate and efficiency of gain and final age of the steers have also been included in this study. Review of LiteratureBlack et al. (1938) concluded from the analysis of data of 50 steers of beef, dual-purpose, and dairy breeding that at 900-pounds live weight the taller and rangier type of animal has a slight tendency to be less efficient in the use of feed. Width of shoulder and width of chest had small positive correlations with rate and efficiency of gain, and heart girth showed practically no correlation with these factors. Hultz and Wheeler (1927) in a study of 2-year-old Hereford steers concluded that low-set type steers make slightly more rapid and economical gains during a 156-day feeding period than do intermediate or rangy type steers. They report that a 2-year-old steer has the appearance of low-setness when the proportions of his chest depth, heart girth, and paunch to his height at the withers are great.
