Abstract The objective of this study was to evaluate weight gain, feed intake, and feed efficiency in beef heifers while consuming two diets divergent in energy density. Fifty-four yearling Angus and Angus cross heifers (initial body weight = 307.5 ± 30.35 kg) were subject to sequential intake trial...
