A study was carried to observe the changes in the Haematological parameters such as Total Erythrocyte count (TEC), Total Leukocyte Count (TLC), Haemoglobin (Hb), Packed Cell Volume (PCV), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), Total Platelet count and Differential Leukocytes count (DLC) of crossbred cows Karan Fries (KF) (Holstein Fresian × Kankrej) cows during transition period. Blood samples were collected from the jugular vein of the selected animals on -30, -15, -7, 0, +7, +15, + 30 days with respect to expected date of calving. TEC and Hb non-significantly increased on the day of calving. A continuous non-significant reduction observed till 15 day after calving as compared to the day of calving. Highest TLC and PCV value observed on 7th day before calving. Then non-significant reduction was observed on the day of calving. MCV and MCH was increased significantly (p<0.05) on the day of calving as compared to 30 day before calving whereas, highest MCHC observed on 15 day before calving and significantly (p<0.05) decreased on the day of calving. Lymphocyte count significantly (p<0.05) reduced on the day of calving as compare of 30 days before calving. Neutrophil count observed non-significantly decreased on the day of calving as compared to 3 days before calving. Thereafter, significant (p<0.05) reduction was observed till 30 day after calving.
