Various haematological parameters like total erythrocyte count (TEC), total leukocyte count (TLC), packed cell volume (PCV), haemoglobin (Hb), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) were determined in 77 female graded Murrah buffaloes of different ages (2-10 years) from the coastal region of Andhra Pradesh in India under field conditions. Comparatively lower mean values than the standard for estimated haematological parameters were obtained in the graded Murrah buffaloes. A significant increase (P LT 0.05) in the mean value of TEC was observed in 2-3-years-old buffaloes (5.90 +- 0.44 millions/ml) when compared to buffaloes of 3-10 years and above age, in which the mean values are in the range 4.24 +- 0.18 to 4.83 +- 0.24 millions/ml. This report is asupplement to a basal data on haematological parameters in graded Murrah buffaloes.
