Abstract
The article is devoted to the effect of probiotics on the animal body. The purpose of the study is to study the effect of probiotics of individual strains on the functional activity of blood neutrophils and on individual parts of the immune system of the cattle body. Various probiotics are widely used in animal husbandry and make it possible to modernize existing animal husbandry regimens. The task of finding new approaches to optimizing the beneficial flora of the body is extremely relevant. The use of probiotics in livestock production is a cost-effective solution. It has been established that the use of probiotics Lactobacillus spp. and Bacillus sb. accompanied by activation of natural resistance mechanisms. Probiotics also help improve immune status, mainly due to the humoral component, tend to optimize the microbiocenosis of the colon, and have a positive effect on increasing animal productivity. The results of comprehensive studies of the state of the defense systems of the body of cattle and their changes under the influence of the drug expand and deepen the existing data on the effect of probiotics on the homeostasis of animals.
