Abstract. The research is dedicated to a comprehensive study of the influence of sapropel and saproverm “Etkul Energy” when included in the diet for morphological and biochemical indicators of the blood of young cattle. 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 “Etkul Energy” 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 from the Orenburg Lake deposit of the Etkul district in the Chelyabinsk region was used for the experiment. It was established that the introduction of sapropel and saproverm in the ration promoted an increase in hemoerythropoietic function, an increase in the oxygen capacity of the blood, and the intensity of oxidation-reduction processes in the animals of experimental groups. Sapropel and saproverm increase the total protein and its fractions, urea, glucose, total lipids, calcium and phosphorus in the blood, the activity of transamination enzymes. In order to improve the metabolism in the body and improve the performance of meat production, we recommend using sapropel in a dose of 0.75 g/kg; saproverm “Etkul Energy” – 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, blood, morphological and biochemical indicators.
