Abstract
Diseases of the respiratory organs are widespread among calves, causing serious economic damage to livestock. Respiratory diseases are observed mainly among calves up to one year of age (85-100%), of which 10-15% get sick some time. The success of treatment depends on timely diagnosis and treatment. The diagnosis of the disease is made by taking into account the results of laboratory tests (bacteriological, virological, serological) and anamnestic data. The main goal of the conducted work was to study the changes in the blood of calves with bronchopneumonia compared to clinically healthy calves. Experiments were conducted on three groups of animals (five clinically healthy calves, five calves with acute bronchopneumonia, and five calves with semi-acute and chronic bronchopneumonia) selected by analogy. The blood index changes of calves sick with bronchial pneumonia with acute and chronic clinical course in comparison with the same indices of clinically healthy ones are described in the article.
