The paper presents the results of the therapeutic effect of Bacillus megaterium in subclinical mastitis in cows. The aim of the research. To determine the effect of Bacillus megaterium on the microflora of the gastrointestinal tract and colonies of microorganisms isolated from subclinical mastitis in cows. Materials and methods. The research was conducted in a dairy farm growing Holstein. Cows with subclinical mastitis of the experimental groups were given concentrated feed with the addition of Bacillus megaterium (1 × 109 CFU/g) at a dose of 15–35 g per animal. The control group of cows was given the usual diet for dairy cows. The experiment lasted 30 days. Results. The use of Bacillus megaterium (1 × 109 CFU/g) at a dose of 35 g per animal had a pronounced effect on the microflora of the gastrointestinal tract of cows. The amount of Lactobacillus sp. was 67 % higher and Bifidobacterium 58 % higher than the control. In addition, the level of opportunistic pathogens on Escherichia coli decreased by 45 %, Clostridium by 27 %, Enterobacteriaceae and Staphylococcus by 75 %, and Candida by 80 % compared to controls. The amount of microflora in milk decreased by 40.2 % and the number of somatic cells by 87.9 %. Conclusions. The therapeutic efficacy of Bacillus megaterium (1 × 109 CFU/g) at a dose of 35 g per animal for 30 days in subclinical mastitis has been proven. After treatment, the amount of microflora in cow's milk decreased by 40.2 % and the number of somatic cells by 87.9 %. A positive effect on the microflora of the gastrointestinal tract of cows, where the number of Lactobacillus sp. increased by 67 % and Bifidobacterium by 58 %. The level of opportunistic pathogenic microflora decreased by Escherichia coli – by 45 %, Clostridium – by 27 %, Enterobacteriaceae and Staphylococcus – by 75 %, Candida – by 80 %, compared to the control.Yaroslav TytukhYurii MusiienkoNatalia GrebenikScientific Route OÜarticlecowssubclinical mastitisgastrointestinal microfloranumber of somatic cellsMedicineRENTechnology Transfer: Innovative Solutions in Medicine, Pp 32-34 (2021)
