Summary

Thirty-three Hereford x Angus first-calf females were used to determine the relationship between production efficiency (PE = calf weaning weight/l2month dam + calf ME intake) and nonlactating dam maintenance ME requirements (MEm) and its components k, and FHP. Substantial variation existed in PE and energy parameters among individuals. However, maintenance metabolism of the dam contributed little to explaining PE variation (Fs.04). This may have been due to the high plane of nutrition provided. Additionally, FHP was closely related to MEm (r2 = .69), suggesting it could be used as an indicator of fed maintenance requirements.
