Abstract
Genital mycoplasmosis in cattle is characterized by a long course with mild symptoms, which can lead to irreversible changes in the reproductive organs. A study of the influence of genital mycoplasmosis in mothers cows on the vital properties of calves obtained from them was carried out. In calves from these cows, the dynamics of body weight gain and the incidence of diarrhea and bronchopneumonia were monitored for a month in relation to the group of animals obtained from healthy cows. It was found that calves born from cows with mycoplasmosis have significantly less body weight at birth, which is not restored during the first month of life, and the incidence of diarrhea is increased by 19.8% and bronchopneumonia by 15.1%.
