Features of clinical and morphological manifestations of bronchopneumonia in calves

The study analyzes the spreading of bronchopneumonia in young cattle in the SEC ‘Solontsy’ Emelyanovsky district of Krasnoyarsk Region and assesses morphological and func- tional status of calves under the disease. The research was conducted in 2016-2018 at the Department of Anatomy, Pathological Anatomy and Surgery of the Institute of Applied Biotechnology and Veterinary Medicine of Krasnoyarsk State Agrarian University. Comprehensive clinical, hematologicaland bacteriological studies were conducted. Clinical condition of sick animals, morphological indicators of blood were de- fined. It was established that in the SEC "Solontsy" of Emelyanovsky district of Krasnoyarsk Region bronchopneu- monia of calves took the second place in spreading among other diseases of young growth of cattle. The disease is sea- sonal, non-specific and affects young growth at 1-3 months of age.

Hematological changes in calves with bronchopneumonia are characterized by anemia, evi- denced by the decrease in the total number of red blood cells by 27 % compared to healthy animals, moderate leukocytosis accompanied by the increase in the total leukocyte count by 36 % relative to these healthy calves, neutrophilia and eosin- ophilia.
