The comparative beef productivity characteristics of Simmental bulls and their crossbreeds with the Hereford and Charolaise were demonstrated in the article. 3 groups of calves with 17 heads each were selected and formed for the experiment. Simmental bulls were included to the first (control) group, mixed bred calves receiving from the crossing of Simmental cows with Hereford and Charolaise bulls to the second and the third (experimental) groups. During the whole experimental period, except only after weaned period, Charolaise crossbreeds demonstrated high average daily gains and significantly exceeded other two groups. Average daily gains in groups constituted correspondently: 993, 1014 and 1101g. during whole period of experiment. Crossbreeds Hereford and Charolaise bulls were characterized by a higher slaughter weight and hot carcasses weight in all age periods. At the end of the experimental period the slaughter yield of the maternal breed bulls was 59,3 per cent, and 61,8 and 62,7% of the Hereford and Charolaise bulls correspondently. However, slight deposition of subcutaneous and internal fat was observed in Sharolaise crossbreeds.
