All the calves weaned in this study were self-fed whole oats as a creep ration for at least 30 days prior to weaning. After weaning, they were fed the rations shown in Table I . Table I. Rations used for early weaned calves at U.S. Meat Animal Research Center. 15.8 15.2 14.8 Advantages of Early Weaning It aids in ensuring a calf from each cow every 12 months. Dams of early weaned calves should cycle earlier.
Calves can grow to their genetic potential regardless of the dam's milk production.
It may be the key to more efficient feed utilization during times of drought or other periods of feed shortage. Fifteen to 20 percent less energy is needed to feed early weaned calves and their dams as compared to cows nursing their calves. It fits in with fall calving where heavy winter feeding would otherwise be required. Early weaning permits more cows to be carried on a limited feed supply. It may be possible to get cheaper gains due to the excellent feed conversion of early weaned calves.
