Abstract
The aim of this study was to investigate the treatment-related changes in hematological parameters in dairy cows affected by clinical endometritis (CE) and subclinical endometritis (SE). One hundred seventy postpartum Holstein dairy cows were selected from a large commercial dairy farm. Cows of the SE group presented a significant decrease in PCV (P < 0.05) and red blood cell (RBC) (P < 0.05) values, when compared to healthy group, while the CE group presented a significant decrease (P < 0.01) in PCV and RBC count, when compared to healthy and SE animals. Significant increases in white blood cell (WBC) (P < 0.05), neutrophil (P < 0.001), and lymphocyte (P < 0.001) counts, in the CE and SE groups, were observed when compared to healthy cows. After treatment for CE, PCV and RBC count dropped significantly, whereas WBC, neutrophil, lymphocyte, and monocyte counts decreased significantly (P < 0.05). In the SE group, WBC, neutrophil, lymphocyte, and monocyte counts decreased significantly after treatment (P < 0.05). The results obtained in this study confirm endometritis-induced changes in hematological parameter which improve after treatment.
