The results of studying the effect of the prebiotic feed additive “Vetokislinka” on the microflora of feces, hematological parameters and the growth rate of calves of the milk period are presented. Calves of the control group received the basic diet without the inclusion of the studied prebiotic. The calves of the experimental groups were fed with the prebiotic Vetokislinka in a dose of 0.8 in addition to the basic diet; 1.0 and 1.2 ml per 1 liter of drinking water from 6-10 to 90 days of age, daily frequency, 2 times a day (50% of the daily value). According to the research results, it was found that an effective dose of the prebiotic feed additive “Vetokislinka” was a dose of 1 ml per 1 liter of drinking dose, which had a positive effect on the microbial landscape of feces in calves, in which there was a significant increase in the number of normal flora: lactobacilli and bifidobacteria, as well as a decrease in Escherichia. Within the physiological norm, the use of the prebiotic “Vetokislinka” promoted an increase in erythrocytes by 9.1%, hemoglobin by 11.3%, platelets by 15.2% compared to the first control group (p < 0.05). The average daily gain of calves was significantly higher by 9.8%, while reducing feed costs per 1 kg of live weight by 8.8%. The economic efficiency from the introduction of the prebiotic supplement “Vetokislinka” into the diet of calves, at a dose of 1 ml / head per 1 liter of drinking water, per calf was 561.6 rubles.
