Abstract
A typical method of rearing calves in Egypt is to provide 340 kg whole milk to an age of 120 days. In 4 experiments with a total of 314 cattle and buffalo calves systems of early weaning with a minimum of 31 days and 67 kg whole milk were compared with the typical system. Different additives including vitamins, minerals and a microbial growth stimulant, Bosphoroplus, were incorporated in the concentrate mixtures in some experiments. The mixtures were of grain or grain products and plant protein meals with 8% molasses, with or without 10% dried skimmed milk. Satisfactory growth could be obtained by weaning at 45 days with a total of 103 kg whole milk. It was shown in one experiment that for light calves, weaning at 31 days gave poor performance, particularly if the calves were female.
