Abstract:

Six crossbred cows (Holstein Friesian × Kankrej) were investigated in their advance stage of gestation period for Phagocytic Activity (PA) of Blood and Milk. Blood was collected on days -30, -15, -7 and -3 before calving, on the day of calving and on days 3, 7, 15 and 30 after calving while milk collected on the day of calving and 3, 7, 15, 30 day after calving. Highest Neutrophil (%) was observed on 3rd day before calving which was significantly (p<0.05) higher as compared to 30 day before calving. The PA of blood was observed significantly (p<0.05) lower at calving as compared to 15 day before calving. While the PA of milk neutropil was significantly (p<0.05) higher at calving as compared to 7, 15 and 30 days postpartum. Cortisol level was increased significantly on the day of calving as compared to pre-partum and postpartum days. This study indicated that the phagocytic activity of blood and milk neutropils get reduced during calving. Increasing level of glucocorticoids during calving is responsible for immunosuppression during peripartum period.
