The purpose of this study was to investigate the specific features of consumption and utilization of nutrients, energy and nitrogen in the diet of steers of the Kazakh white-headed breed while feeding with a balanced carbohydrate complex Felutsen for beef cattle. A beneficial effect of including a balanced carbohydrate complex Felutsen into the ration of steers of experimental groups on the level of intake of nutrients from the feed rations has been established: There was an advantage of young bulls of groups II-IV over bulls of group I (control) on the consumption of dry matter 215.0–302.5 g (2.4 – 3.4%), of organic matter 177.1 – 330.7 g (2. 2 – 4.0%), crude protein 14.4 – 44.3 g (1.3 – 4.0%), crude fat 3.7 – 6.5 g (1.3 – 2.3%), crude fiber 26.4 – 46.6 g (1.3 – 2.3%), nitrogen-free extractive substances 100.0 – 200.7 g (2.1 – 4.2%). The positive effect on the utilization of all types of nutrients was also established, so the bulls of I (control) group were inferior to the young animals of II-IV experimental groups in terms of the coefficient of digestibility of dry matter by 1.15–2.11%, organic matter 0.98–2.88%, crude protein 0.85–1.19%, crude fat 1.13–2.11%, crude fiber 0.36–0.67%, nitrogen-free extractive substances (NES)-1.16–4.22%. The results indicated the outperformance of the II-IV experimental groups over the I (control) group in terms of energy consumption with feed protein by 0.35–1.06 MJ (1.3–4.0%), Fats energy - by 0.15–0.26 MJ (1.3–2.3%), fiber energy - by 0.52–0.93 MJ (1.3–2.2%), nitrogen-free extractive substances energy - by 1.75–3.51 MJ (2.1–4.2%). Bulls of the II-IV experimental groups exceeded their peers of the I (control) group in nitrogen intake by 2.30–11.63 g (1.3–6.5%). Similar intergroup differences were observed in terms of digested nitrogen.
