Hematology of dairy cows with purulent-necrotic processes in the digital area treated with Subtilin ointment.

Abstract

The objective of this study was to investigate the effect of Subtilin ointment on the hematology of dairy cows when used to treat inflammation and necrotic tissue in the digital area. Holstein-Friesian cows were allocated to 2 groups of 10 animals each. The first group consisted of clinically healthy cows and the second group consisted of cows with a purulent-necrotic lesion in the digital area. To make a comparative analysis, blood samples of healthy and diseased cows were taken and tested before treatment with Subtilin ointment and 10 days after treatment. The blood of the diseased cows had more leukocytes (53.38%), lymphocytes (46.81%), erythrocytes (15.78%), granulocytes (64.56%), and platelets (34.76%), and a higher mean cell volume (of 8.37%) and increased level of monocytes/eosinophils (65.12%) than did the blood of clinically healthy cows. At the same time, there were no evident changes in the level of erythrocytes, hemoglobin, mean cell hemoglobin, mean cell hemoglobin concentration, and percentage of lymphocytes in either clinically healthy or diseased cows. The hematology of diseased cows treated with Subtilin ointment demonstrated positive dynamics in the healing of ulcerative processes.
