The effect of pre- and probiotic preparations on the state of the intestinal microflora of healthy and sick calf dyspepsia

This article describes the effect of pre- and probiotics on the condition of intestinal microflora for
newborn calves. It has been established that in the intestines of calves, in addition to lactic and bifidobacteria,
conditionally pathogenic bacteria such as E. coli, staphylococcus and streptococcus are contained. When taking
pre- and probiotics in the experimental groups of animals, a decrease in the content of conditionally pathogenic
microflora was observed with a dynamic increase in obligate, which indicates a positive effect on the formation
of intestinal microbiocenosis during the milk period.
