The effect of the Tulatromycin in pregnant cows with genital mycoplasmosis on the indicators of nonspecific resistance of their offspring

Abstract

Obtaining healthy young animals with good productive potential is one of the main goals of modern animal husbandry, the implementation of which is hindered by diseases of pregnant females of various etiologies. One of these diseases is genital mycoplasmosis of cattle. To date, there is little information about the effect of this disease in maternal cows on the immune status of offspring. We have studied the effect of therapy of pregnant cows with tulatromycin on the indicators of nonspecific resistance of calves obtained from them. It has been established that genital mycoplasmosis in maternal cows leads to inhibition of bactericidal and lysozyme activity of blood serum, as well as phagocytosis indicators in their offspring. The use of tulatromycin for treatment leads to recovery of 75% of sick animals and causes partial normalization of indicators of nonspecific resistance in their offspring. The revealed changes will optimize the treatment regimen of cows with genital mycoplasmosis.
