Abstract
The aim of the study is to study the effect of the mineral shungite on the intestinal microbiota of
laying hens for the needs of poultry farming.
To solve this problem in the conditions of the vivarium of the International Laboratory of
Molecular Genetics and Poultry Genomics, MVA by K. I. Skryabin, an experiment was set up
on laying hens (Hisex Brown cross). The diet of laying hens of the experimental group differed
from the control group by introducing a feed additive from shungite at a dosage of 1 kg per
ton of feed.
In accordance with the goal, the objectives of the study included the calculation of the index of
bioconsolidation of microorganisms in microbial biosystems and the index of the composition of
chemical elements in shungite and mixed fodder, the construction of a fractal portrait of the corresponding
series of numbers, reflecting the series of numbers of microorganisms or the content of
chemical elements in shungite.
Thus, it was shown that shungite, with its special ratio of chemical elemental composition, favorably
affects the self-organization of microbial-organismal biosystems of the intestines of laying
hens and the intestinal microbiota of laying hens in general. The ratio of chemical elements in
shungite imposes a certain matrix on the ratio of various functional groups of microorganisms in
the intestines of birds, which ensures the best joint activity of microorganisms in converting organic
substrates into nutrients.
