Bull calves of black and white breed grown both in accordance with the technology of dairy farming (the control group), and by the system 'cow-calf' in all age periods, did not show any significant differences in growth and development at all age periods. Cost of feed per 1 kg of live weight gain in calves at foot was 4.3 fodder units, while in the control group the same indexes were higher by 9.3%.It is determined that calves of black-motley breed grown according to the system 'cow-calf' surpassed their coevals grown according to ordinary technology on live weight – by 12,9%, fresh carcass weight – by 21,8%, carcass meat content – by 1,3%.
