Cicatricial digestion of calves under the action of probiotics
The influence of probiotics Lactobacillus spp. and Bacillus Subtilis on the activity of cicatricial microorganisms in 30-day-old calves of the Volyn beef breed. Three (control and two experimental) groups of animals were formed, each with 8 heads. By drinking, the calves of the first experimental gr...

| description | The influence of probiotics Lactobacillus spp. and Bacillus Subtilis on the activity of cicatricial microorganisms in 30-day-old calves of the Volyn beef breed. Three (control and two experimental) groups of animals were formed, each with 8 heads. By drinking, the calves of the first experimental group received Bacillus Subtilis, II – Lactobacillus spp. The rumen content in experimental animals was studied using the fistula method. The research results showed that the mass of cicatricial bacteria and ciliates changed under the influence of probiotics in the experimental groups compared to the control group. There were also changes in the biochemical indicators of the rumen; in particular, the content of ammonia from bacteria and ciliates was likely to decrease (Р < 0.05), and the amount of volatile fatty acids was possible to increase (Р < 0.05). It has been established that probiotic supplements contribute to the accelerated formation of cicatricial microflora and its ability to break down fiber. For example, the probiotic Lactobacillus spp. has a more significant stimulating effect on forming LFA bacteria, and Bacillus Subtilis has a more significant stimulating effect on the LFA of infusoria. Ammonia formation of bacteria and ciliates was lowest under the action of Lactobacillus spp. Probiotics have a positive impact on nitrogen metabolism in the rumen, which contributes to a decrease in the concentration of lactic acid, stimulates the growth of anaerobic bacteria (cellulolytic, lactic acid, and proteolytic), increases digestive processes, and destroys intermediate products of metabolism. Under the action of probiotics, the content of cellulolytic microorganisms in the I and II experimental groups was 1.2 and 1.3 times higher; the number of lactic acid bacteria was 1.7 times higher in both I and II experimental groups, and the number of proteolytic bacteria is 1.5 and 1.3 times higher compared to the control group. |
