Summary
Growth rate of an animal depends upon energy consumed in excess of that for maintenance, and the requirements increase as the animal grows and fattens. Male and female cattle differ in rates of growth and fattening, but changes may be brought about by castration. There still is some concern as to the effects of market weight and energy content of rations on weight gain, feed efficiency and carcass characteristics of feedlot bulls, heifers and steers. This experiment was conducted to study these factors. Bulls ( calves and yearlings), heifers and steers were fed to one of two final weight groups. Rations with about 50% or 9 0 % concentrates were used for each weight and sex group. This report is concerned with the feedlot performance data. Results of the study on carcass data are presented in another report (A.S. Series 73-37).
