Comparative of Neutrophils and Lymphocyte Ratio for Dairy Cattle in Prepartum and Postpartum Condition

There is a transition period that dairy cattle always pass through in their reproduction cycle, making them more stressed. Stress can simply be identified by the ratio of neutrophil (N) and lymphocyte (L) at haematologic state cattle. The purpose this study to evaluate stress conditions cattle’s based on ratio. Twenty samples blood prepartum postpartum condition are being analyzed with hematology analyzer. result shows average has increased insignificantly from as 4.14 103/µL ± 1.51 4.27 2.08 or 1.03% normal interval 1.7-6.0 103/µL. However, lymphocytes decreased 3.23 1.13 3.03 1.23 0.93% 1.8-8.1 Then, 1.35 0.46 1.47 0.60 1.09%. Based result, neutrophils per still range. In period, only few have stressful condition. increasing (neutrophilia) reducing (lymphocytopenia).
