Intestinal microbiote of the BLV-infected cows offspring under dyspeptic manifestations prevention

Abstract

Dyspeptic symptoms are common in neonatal calves from BLV-infected cows. A single drinking of the made by authors composition (patent No 2646831) prevents dyspepsia in animals. The article is devoted to the analysis of representative indicators of intestinal microbiota of the calves from infected with leukemia cows, under dyspeptic manifestations prevention. It was shown that by the 14th day after drinking the composition, the number of intestinal Lactobacillus in calves increased and was 2 times higher than in animals without drinking the composition. The quantity of Bifidobacterium in newborn calves of the control group at first sharply decreased, and then gradually restored. In the experimental group calves, the dynamics of Bifidobacterium was positive. Conditionally pathogenic Enterococcus and Escherichia coli were presented in the control group of calves in an order greater than in animals of the experimental group, and Staphylococcus - almost 2 times higher. The Proteus and yeast-like fungi content normalization in the both groups calves occurred rather quickly under the influence of normal intestinal microflora. Thus, use of the original composition for dyspeptic manifestations prevention in neonatal calves from immunocompromised cows, promotes the rapid colonization of the calves intestines with normal microflora.
