The economic feasibility of complex therapy of calves with bronchopneumonia

The manifestation of the pathogenetic mechanisms of bronchopneumonia depends on the penetration of pathogenic or conditionally pathogenic microorganisms into the alveoli and bronchi. With the development of the clinical picture of bronchopneumonia in calves, the concentration of erythrocytes and hemoglobin decreases from the morphological indicators, but the content of leukocytes increases and the ESR rate accelerates. Neutrophilia with a regenerative shift to the left is observed in the leukocyte formula, and a significant number of juvenile and rod-shaped neutrophils appear. At the beginning of the inflammatory reaction, eosinophils are activated. There is a decrease in lymphocytes among agranulocytes, which is probably due to their participation in cellular and humoral immunity. A significant decrease in total protein in the blood serum indicates the development of hypoproteinemia, an increase in urea levels confirms the opinion about increased excretion of the final product of protein metabolism. A decrease in the concentration of glucose and cholesterol in the blood of sick calves indicates a shortage of energy resources. A decrease in carotene content by 3 and 5 times in a comparative aspect with healthy calves, signals the problem of vitamin A synthesis in the liver. The clinical manifestation of bronchopneumonia in sick calves was manifested in an acute form. Subfebrile temperature, increased pulse rate and respiratory movements were recorded in sick young animals. Viscous serous catarrhal exudate was secreted from the nasal openings. Auscultation revealed a dry, painful cough, mixed shortness of breath. The use of complex therapy of calves with bronchopneumonia contributed to the recovery of young animals of the control group only by the 12th day of treatment. The inclusion of an antimicrobial drug, an active immunostimulator and a stabilizer of metabolic processes in the treatment regimen of the experimental group contributed to the complete recovery of young animals by the 10th day of course therapy. The use of complex therapy in the experimental group is economically advantageous, since 2.6 rubles of profit account for 1 rub of costs.
