Abstract

The work is devoted to the study of the self-organization of microbial communities in the intestines of chickens in different conditions of keeping and feeding chickens and the development on this basis of a mathematical model for determining the index of fractal structures to assess the effectiveness of probiotic feed additives on the microbiota of the intestines of chickens.
The experience with chicken diets showed that the level of self-organization of microbial communities in the intestines of chickens depends on the probiotics used. The best indicator of the organization of the microbial community is the experimental version with a probiotic based on Lactobacillus fermentum. It was shown that the index values of the fractal structures of microbial communities in the intestines of chickens when using various probiotic preparations for different experimental schemes are as follows: OP1 – 0,292; OP1 + Probiotic 1 – 0,286; OP1 + Probiotic 2 – 0,354 and the developed mathematical model can be used to evaluate the effectiveness of probiotic feed additives on the microbiota of chicken intestines.
