EFFICIENCY OF USING SAPROPEL AND SAPRVERM “ENERGY ETKUL” IN RATIONS OF YOUNG CATTLE
The studies are devoted to a comprehensive study ofthe influence of sapropel and saproverm“Energy Etkul” when they are included in the ration of young cattle forthe efficiency of beef production.To conduct the scientific experiment, three groups of Simmental bulls ofAustrian breeding were formed with 10 heads each. During the reference periodthe animals were in the same conditions of feeding and maintenance. Theyoungest of the control group received the main diet taken in the farm. Inaddition to the main diet, the animals of the experimental groups receivedsapropel and saproverm “Energy of Etkul” in the amount of 0.75 and 0.95 g/kg oflive weight per head per day, which were set in a mixture with concentratedfood during the morning feeding for 15 days. Introduction to the diet ofsupplements was carried out from 6 months of age and before slaughter with aninterval between introducing them into the diet for 15 days. Sapropel of theOrenburg deposit of the Etkul district of the Chelyabinsk region was used forthe experiment. It was established that the introduction ofsapropel and saproverm “Energy Etkul” into theration facilitated a reduction in the costs of the main feed substances for theproduction of 1 kg of products and an increase in the conversion rates ofprotein and energy of the feed into food protein and the energy of the ediblepart of the carcass. Sapropel and saproverm allow reducing production costs,increase profit and profitability of production. The greatest effect in theproduction of beef is provided by the use of the saproverm “Energy Etkul”. In order to increase the efficiencyof beef production, we recommend using sapropel in a dose of 0.75; saproverm “Energy Etkul” — in a dose of 0.95 g/kg of liveweight per head per day during the periods of growing and fattening.
