N2 - The development of diarrheal syndrome in calves is a serious problem and causes great economic losses for cattle breeding. There are infectious and non-infectious causes. The prevention of such conditions is based on the correct colonization of the symbiotic microflora of the gastrointestinal tract in calves during the neonatal period. Another important factor is the use of probiotic bacteria to regulate metabolism and microbiome. The purpose research was to find out determine evaluate the rate of elimination of bacteria of the genus Bacillus subtilis from the body of dairy cattle calves, as well as the effect of probiotics on diarrhea and changes in the microbiome. For this purpose, changes in the consistency and bacterial diversity of faeces were evaluated in animals before and after the use of a probiotic strain of B. subtilis bacteria. The results of the study show the restoration of gastrointestinal tract function in calves with signs of diarrhea. During the study, a change in the microbial community was observed under the influence of B. subtilis bacteria. The study showed that before the use of probiotics in crops on nutrient media, fungi of the genus Candida tropicalis were detected in calves of the experimental and control groups, however, after the use of probiotics in calves of the experimental group, these fungi were not detected already on the first day after completion course. The study supported the hypothesis that probiotic bacteria B. subtilis participate in restoring the function of the gastrointestinal tract in calves with diarrhea and affect the microbial community.
