Material and methods The article presents the results of studies of technologies of feeding and keeping animals, the study of live weight and average daily growth of domestic Kazakh white-headed breed and foreign Hereford and Aberdeen-Angus breeds. Results The results of comparative analysis of live weight and average daily growth of young animals of different breeds grown in the semi-desert zone of Western Kazakhstan are presented. It is established that the average daily gain in live weight for the period of cultivation from 8 to 15 months was at Hereford breed in bulls 658,1 g and heifers - 587,1 g at Aberdeen Angus, respectively, 603,8 and 500,9 g, at Kazakh white - 758,8 and 561,1 g.
