Abstract
The stress of weaning piglets negatively affects all factors of the body. First of all, this affects the violation of nutrition and a decrease in the activity of the immune system. The use of probiotics allows to reduce the negative consequences caused by weaning from a sow. The aim of the study was to study the effect of probiotics based on Lactobacillus reuteri on the indicators of nonspecific resistance and productivity of piglets. The obtained data showed a high efficiency of the use of probiotics. In the experimental group, the phagocytic activity of neutrophils increased by 4.4%, the phagocytic index was 6.6% higher, and the bactericidal activity increased by 29% compared to the control group. In piglets treated with Lactobacillus reuteri, body weight increased by 9.3%, and the average daily gains in the control group increased by 15.8%. The use of probiotics in the period of stress after weaning allows you to activate the immune status.
