Повышение колонизационной резистентности микрофлоры желудочно-кишечного тракта коз

Abstract

The study was conducted to increase the colonization resistance of the microflora of the gastrointestinal tract of young goats of the Saanen breed through the use of the Extrasol preparation based on Bacillus subtilis Ch-13 (LLC Bisolbi-Inter). In the course of the study, scientific and production experience was carried out in the Samara region on 20 Saanen goats: 10 heads in the control and experimental groups. As a result of the study, it was found that the drug «Extrasol» increases the intensity of the process of energy and substance metabolism in the body of animals. The concentration of total protein in the blood serum of goats of the experimental group at 120 days of age was higher by 9,7 %, albumin by 33%, blood glucose by – 11,2 % compared with the control. The proteolytic, anti-lysozyme, anti-carnosine activity of enterococci, the ability of microorganisms to form biofilms was higher in the goats of the experimental group due to the use of the Extrasol preparation. Body weight of kids in the control group at 120 days of age was 21,32±1,79 kg, in the experimental group – 23,25±2,58 kg, which is 1,93 kg higher. The average daily gain in the experimental group was significantly higher by 0,029 kg. As a result, the administration of Extrasol as a probiotic in addition to the basic diet of young goats of the Saanen breed from 60 days to 120 days of age leads to an increase in the rate of growth and development of animals, an increase in colonization resistance and antagonistic ability of the resident microflora of the gastrointestinal tract of animals. The economic efficiency of using the Extrasol preparation is due to the possible profit from the sale of meat from young goats of the experimental group, which was higher by 70,81 rubles from each head.
