It has been established that biologically active substances must be used at certain periods in the life of piglets and in certain dosages. The use of a probiotic based on bacteria of the Bacillus of the B. subtillus and B. amyloliquefaciens bacilli strains at a rate of 20 g per head from the 8th to the 28th and from the 35th to 90th days of life caused “overpopulation” of the body of young animals with bacteria. It led to the inhibition of biochemical blood parameters. This consisted in a decrease in the total amount of protein and γ-globulin fraction, and in an increase in the level of glucose in the blood of piglets by 2.1 and 2.6 mmol/L.  Therefore, it led to a violation of protein and carbohydrate metabolism. Using a probiotic at the rate of 5 g per 1 head from the 8th to the 15th day, 10 g from the 24th to the 28th and from the 35th to the 90th day of life allowed improving the redox processes of the body.
