| Abstract | This work focused on the effects of yeast probiotic supplements on the metabolic rate in calves up to six months of age. Studies have established that the use of the optical-yeast probiotic supplement Optisaf in the diets of young cattle at a dose of 10 g per animal per day increased the digestibility of dry matter by 3.71% (P <0.05), organic matter 2.95%, crude protein 4.26% (P <0.01), crude fat 3.95% (P <0.05), crude fiber 2.85%, and nitrogen-free extract fractions (NFE) by 2.41%; increased the efficiency of metabolic energy and nitrogen by 6.91% (P <0.01) and 2.42%, respectively; contributed to the better utilization of calcium and phosphorus by 6.32% and 9.95%, respectively, in comparison with the experimental control group. The use of Optisaf yeast probiotic supplement led to an increase in the number of Lacto- and Bifidobacteria in the intestines of the 3rd experimental group by 42.19% (P <0.05) and 45.93% (P <0.05), respectively, and a decrease in the number of E.coli bacteria by 36.14%, compared with the control group. The introduction of Optisaf supplements into the diet of calves had a positive effect on their physiological state. The number of erythrocytes in the blood of calves of the 3rd experimental group increased by 9.20% (P <0.05), the hemoglobin content by 9.35% (P <0.05), total protein by 9, 11% (P <0.05), phagocytic activity by 3.67%, compared with the control group. |
