Abstract

Intestinal microbes play a key role in the energy metabolism of broiler chickens, participate in the development of the gastrointestinal tract, including the regulation of intestinal epithelial proliferation, vitamin synthesis and ion absorption, fermentation of carbohydrates and proteins, biotransformation of bile acids, protection from pathogens and modulation of the immune system. Metagenomic analysis of the gastrointestinal microbiota allows to find approaches to improve the growth and productivity of chickens by introducing a diet based on beneficial bacterial strains or their secondary metabolites. In this paper, we studied the effect of the total fraction of Bacillus subtilis GM5 lipopeptides on the growth parameters and formation of bacterial communities in the caecum of cross Cobb 500 broiler chickens. It was found that the addition of bacillary lipopeptides to the feed resulted in an increase in chicken weight by 12.7% and a decrease in feed conversion by 6.36% compared to the control (P < 0.05). It was also shown that the introduction of a feed additive in the form of a lipopeptide fraction modulates the structure of the bacterial microbiota of the caecum of chickens. Thus, the proportion of classes Bacteroidia, Negativicutes, Betaproteobacteria, Epsilonproteobacteria, Deltaproteobacteria, Synergistia in the caecal microbiota of chickens of the experimental group increases, and the proportion of Clostridia, Methanobacteria decreases in comparison with the control.
