The statistical data on the incidence of bronchopneu-monia in Simmental calves were collected and analyzed on the farm of the AO “Imeni Gastello”, the Khabarskiy District of the Altai Region. This disease is widespread among young animals. Most often, bronchopneumonia is caused by bacterial microflora; the disease is frequently associated with a violation of veterinary hygiene requirements. The danger of bronchopneumonia for young animals lies in the fact that not only the lungs are affected, but also the entire bronchi. After analyzing the collected data at the livestock complex and according to the information of the veterinary registration log, bronchopneumonia was detected in 967 calves at the age of 4-6 months from 2017 through 2020. In 2020, the largest number of young animals (221 heads) was affected. According to the study, a high incidence of bronchopneumonia was observed from October through April each year; in April 2019, a high outbreak of broncho-pneumonia was recorded in calves (60 heads). In spring and summer, bronchopneumonia is detected only occa-sionally, or there are no cases at all. Bull-calves are more often affected by the disease; cow-calves are more re-sistant to this disease. There was no loss of young cattle from 2017 through 2019; in 2020, 4 animals died. Simmen-tal calves are treated with Streptomycinand Mucaltin. As prevention, it is advised to follow the veterinary hygiene requirements for young-stock barns and decontaminate manure and litter.
