Dynamics of indicators of non-specific resistance in cows with genital Mycoplasmosis on the background of therapy with Tulathromycin

Abstract

Modern livestock breeding technologies imply the maximum use of the productive potential of animals. Animal diseases of various etiologies are a significant obstacle to the fulfillment of this task, causing significant economic damage, consisting of a shortage of products, restrictions on its sale and treatment costs. One such disease is genital mycoplasmosis in cattle. The aim of our research was to study the effect of treatment of genital mycoplasmosis in cows with tulathromycin on some indicators of nonspecific resistance. Studies were carried out on two groups of pregnant cows, a group of animals with mycoplasmosis was treated with tulathromycin, healthy cows served as controls. In both groups of animals, the activity of lysozyme, bactericidal activity of blood serum, phagocytic activity and phagocytic index were determined. It has been established that the use of tulathromycin leads to the recovery of 75% of infected cows, and also leads to an increase in phagocytosis, which does not significantly differ from the level of healthy animals. To a lesser extent, the use of this drug in genital mycoplasmosis affects the bactericidal and lysozyme activity of blood serum.
