Summary. In the necessary correction and prevention of dysbacteriosis in animals and humans, the main role is played by the use of probiotics. Probiotics are live microbial supplements that have a beneficial effect on the body by forming a full-fledged barrier of the intestinal mucosa, preventing the attachment of pathogens to it, modulating the body’s defense mechanisms and improving the balance of intestinal microflora. This is achieved by directly antagonizing bacteria and increasing the effectiveness of the immune response. The normal microflora of the intestine of poultry is 99% composed of anaerobic bacteria. It was found that probiotics activate the tissue and humoral immunity of animals (T- and B-lymphocyte systems), affect the production of immunoglobulins. To study the effect of a probiotic complex based on fermented milk and propionic microorganisms Streptococcus lactis and Lactobacillus acidophilus, an experiment was carried out on broiler chickens of the KOBB-500 cross. The feed additive «Prolaxim-V» was introduced with water in the watering system in the amount of 0.2 ml per 1 bird/ day. Its use increased the gain in live weight of chickens by 10.4%, improved the indices of intestinal microbiocenosis. The number of lactobacilli, lactococci and bifidobacteria in the intestine increased 5 times compared to the control. Based on the data obtained, it can be concluded that the use of lactic acid starter cultures with live lactobacilli in poultry diets during growing periods should be recommended to obtain higher growth rates, improve the physiological state of animals and the quality of meat products.

Keywords: poultry, broiler chickens, diet, live weight gain, probiotic complex, live weight, microbiocenosis, lactobacilli, lactococci, bifidobacteria.
