Abstract

The article presents the results of the study of the characteristics of consumption and intake of nutrients, energy, and nitrogen by steers of the Kazakh white-headed breed and its different generations crossbreeds with Herefords. The purpose of the study was to identify the most potentially productive crossbreeds of the Kazakh white-headed breed for the meat industry and a detailed study of their nutrient intake. Analysis of the obtained experimental data confirms the dominant influence of young cattle's genotype on the assimilation of nutrients and energy. According to the results of the experiment, crossbreeds of the first generation (1/2 Hereford x 1/2 Kazakh white-headed breed) of the II experimental group and crossbreeds of the second generation (3/4 Hereford x 1/4 Kazakh white-headed) of the III experimental group surpassed their purebred steers of the Kazakh white-headed breed I (control) group in the assimilability of all types of nutrients. However, the best results were shown by the III experimental group.
