The dynamics of live weight and slaughter indicators of Kazakh white-headed bulls were studied when the vitamin and mineral premix was introduced into the diet. Animals that were fed with a premix in a concentration of 1% along with the main diet exceeded their peers in live weight at the age of eight months by 4.38 kg (2.03 %), and at 18 months, at the end of the experiment, by 20.4 kg (3.89%). Control slaughters showed that the slaughter weight of the bulls of the experimental group was better than the control by 25.27 kg (7.64 %), and the superiority in slaughter yield was 2.49 %.
