The effects of calf weaning age on cow and calf performance, reproduction, and feed utilization were investigated in a two-year study. Early weaning increasedcow BW in January. Pregnancy rates were not impacted by calf age at weaning. Dry matter intake (DMI) was similar between normal-weaned cow-calf pairs and early-weaned cows and calves. Feed requirements and utilization were comparable between early- and normal-weaned pairs when fed high energy diets, implying weaning decisions should be made on the basis of management rather than feed efficiency.
