| Summary: | Studies on the effectiveness of the inclusion of sodium humate in the diet of young cattle were conducted on four groups of animals. Installed improvement in the consumption of hay by the bulls of the experimental groups by 12.5–20 % compared with the control young was found, as a result of which they consumed more feed units by 1.5, 2.3, and 3.5 %, exchange energy – by 2.4, 3.9 and 5.1 %, digestible protein – by 1.2, 2.1 and 3.7 %. As a result of the inclusion of sodium humate in the diet as part of the KR-2 compound feed, the amount of hemoglobin in the blood of animals of the II experimental group increased by 5.8 %, in III – by 6.8, in IV – by 7.8 % compared to control analogs. With the growth of calves in the blood, the bactericidal activity of blood serum increased by 1.3, 1.9, and 2.5 %, lysozyme activity increased by 0.1 %, 0.2, 0.3 %, which indicates an increase in natural resistance in animals whose diets were injected with the studied peat and sapropel preparation. The use of sodium humate in the feed of bulls in the composition of compound feed KR-2 has a positive effect on the feed consumption, physiological condition, resistance of animals, which provides an increase in the average daily increase in live weight by 3.2–9.4 % while reducing the cost of its production by 2.9–8.5 percent.
