The article provides information on the species composition of the microflora of the digestive tract in chickens of the Dekalb cross, its changes during the period of early postembryonic development against the background of the introduction of biologically active substances. The assessment of the degree of influence of the use of monopreparations and their combinations is given. The study was carried out in 2020 at the Department of Obstetrics, Surgery and Non-communicable Animal Diseases of the Ivanovo State Agricultural Academy. The initial analysis of the microflora of the digestive tract was carried out in 5-day-old chickens. Chickens of experimental groups 2, 3 and 4 were injected with biologically active substances, respectively, probiotic Zoonorm at a dose of 0.2 g per head in the morning mixed with feed; a 0.3% suspension of an enterosorbent based on polymethylsiloxane polyhydrate was drunk 2 hours after the last feeding and a combination of two drugs at the appropriate time. The drugs were used for 20 days, the study of the composition of the intestinal microflora was carried out in 15- and 25-day-old chickens and 10 days after drug withdrawal. The results showed that during the critical period of development in the control and experimental groups of chickens there is a decrease in the number of intestinal residents. In control chickens, proliferation of Enterobacter cloacae is noted and the number of clostridia increases. Against the background of the probiotic, the number of lactobacilli, enterococci and E. coli (typical) increases and is restored. With the introduction of enterosorbent, the content of lactobacilli increases, proliferation of Enterobacter cloacae is absent throughout the experiment. The combination of probiotic and enterosorbent prevents the development of pathogens, stimulates the growth of lactobacilli, enterococci and stabilizes the amount of typical E. coli and bacteroids. Scientific novelty lies in the establishment of a regulating and stabilizing effect on the intestinal biome of a combination of probiotic and enterosorbent; elucidation of the metabolic and antagonistic function of bifidobacteria in chickens at an early stage of postembryonic development.
