Summary. The results of studies on the use of cavitation-treated grain mix and wheat bran in the diets of young cattle reared for beef indicate the economic feasibility of practical application.

Thus, animals of the experimental groups I and II, that were fed with diets with cavitated grain mix and wheat bran, had live weight of 425.7 and 426.5 kg, respectively, while the live weight of control animals receiving crushed grain mix was  409.3 kg which is 16.4 and 17.2 kg higher. At the same time, the gross growth for the main period of young stock growth was 1.19 centners in the control and 1.33; 1.35 c – in two experimental groups, which is 0.14 c (11.76%; P≤0.01) and 0.16 c (13.44%; P≤0.001) more. This influenced the reduction in the cost per unit of growth in live weight of young animals by 1.3 and 2.0%.

The result of the analysis of the comparison of profitability indicators and total costs showed that the profit from the sale of 1 kg of live weight gain of young animals of groups I and II receiving cavitationally prepared concentrates was higher by 161.2 and 107.7 rubles. or 7.2 and 5.0% compared with their traditional preparation in the form of crushing. The inclusion of cavitated grain mixtures and wheat bran in the diet of young animals contributed to an increase in profitability by 2.6% and 1.7%.

Thus, the introduction of cavitated grain mixes or wheat bran into the diet of red steppe bulls makes it possible to recoup the costs of their preparation with the resulting products with higher efficiency than with traditional crushing.

Key words: bulls, Red Steppe breed, feeding, diets, cavitated grain mix, cavitated wheat bran, live weight, gross growth, cost, profit, profitability.
