Currently, the search for alternative ways to replace the use of antibiotics in animal husbandry is being intensively conducted all over the world, including in Russia. One of the possibilities for the replacement of antibiotics in feed mixtures is the development and testing of probiotics in production conditions. They are biomass of bacteria in the vegetative or spore form with a clearly expressed antagonistic activity against the pathogenic and conditionally pathogenic microflora of the gastrointestinal tract chyme. The paper presents the results of a study on the use of the BioPrimum Sukhoy (dry) feed additive added in different dosages into cows' diets. It was found that the introduction of the feed additive in the composition of the cows' diets at a dosage of 75 mg/kg of dry matter of feed resulted in an increase of red blood cell count and hemoglobin content in the blood by 11.40 and 6.05%, respectively, compared with analogs of the control group. There was an increase in milk productivity by 13.8%, in the amount of milk fat by 14.8% and milk protein by 14.2%.
