Abstract: The present study was conducted to investigate changes in hematological parameters during different stages of lactation in Surti buffaloes. 10 healthy lactating Surti buffaloes were selected for the study. Whole blood containing anticoagulant was collected at early (30±5 days), mid (100±5 days) and late lactation (200±5 days) and used for analysis of hematological parameters. Haemoglobin, total erythrocyte concentration, packed cell volume and lymphocytes increased significantly (p≤0.05) whereas total leukocyte count, neutrophils, eosinophils, basophils and monocytes decreased significantly (p≤0.05) from early to late lactation. Mean corpuscular volume and mean corpuscular hemoglobin did not differ significantly. Mean corpuscular hemoglobin concentration was significantly (p≤0.05) highest in late stage of lactation than early and mid stage of lactation. It was concluded that hemoglobin, total erythrocyte concentration, packed cell volume and lymphocytes increased whereas total leukocyte count, neutrophils, eosinophils, basophils and monocytes decreased from early to late lactation in Surti buffaloes. Thus, it is important to monitor hematological parameters during different stages of lactation in Surti buffaloes.
