Abstract
The article presents data on the study of the effectiveness of a probiotic based on two strains of Lactobacillus reuteri on the indicators of nonspecific resistance and productivity of weaned piglets. The normalization of the digestive tract microflora under the action of probiotics, manifested in an increase in the number of lactobacilli and bifidobacteria, with a simultaneous decrease in the number of salmonella, as well as the stimulation of non-specific immunity, together led to an increase in the growth rate of piglets. At the end of the experiment, the live weight of piglets treated with Lactobacillus reuteri was 9.3% higher and the average daily gains were 15.8% higher than the control group. At the same time, feed costs per 1 kg of growth decreased by 13.6%. This allows the use of probiotic strains of Lactobacillus reuteri in the diet of piglets to increase non-specific resistance and growth indicators in the post-weaning period.
