The development and implementation of new and safe means of treating subclinical mastitis (SM) in the production process remains a pressing problem.

A decrease in inflammation was indicated by a decrease in POM370 (by 2.2 times) and POM430 (by 2.8 times). No significant changes in the blood serum indices of cows were observed.
