Abstract. The studies are devoted to a comprehensive study of the influence of sapropel and saproverm “Energy Etkul” when they are included in the ration of young cattle for the efficiency of beef production. To conduct the scientific experiment, three groups of Simmental bulls of Austrian breeding were formed with 10 heads each. During the reference period the animals were in the same conditions of feeding and maintenance. The youngest of the control group received the main diet taken in the farm. In addition to the main diet, the animals of the experimental groups received sapropel and saproverm “Energy of Etkul” in the amount of 0.75 and 0.95 g/kg of live weight per head per day, which were set in a mixture with concentrated food during the morning feeding for 15 days. Introduction to the diet of supplements was carried out from 6 months of age and before slaughter with an interval between introducing them into the diet for 15 days. Sapropel of the Orenburg deposit of the Etkul district of the Chelyabinsk region was used for the experiment. It was established that the introduction of sapropel and saproverm “Energy Etkul” into the ration facilitated a reduction in the costs of the main feed substances for the production of 1 kg of products and an increase in the conversion rates of protein and energy of the feed into food protein and the energy of the edible part of the carcass. Sapropel and saproverm allow reducing production costs, increase profit and profitability of production. The greatest effect in the production of beef is provided by the use of the saproverm “Energy Etkul”. In order to increase the efficiency of beef production, we recommend using sapropel in a dose of 0.75; saproverm “Energy Etkul” — in a dose of 0.95 g/kg of live weight per head per day during the periods of growing and fattening.
Keywords: sapropel, saproverm, bulls, рrotein conversion factors and feed energy.
