Haematologic analysis is not only relevant for diagnosing disorders of the haematologic system but also helpful in the diagnosis of many organ and systemic diseases. The present study was undertaken with the objectives of establishing the normal reference values of certain haematological parameters in below one year calves of Kosali breed of cattle in their native tract in central plain region of Chhattisgarh state. Determination of red blood cell or erythrocyte (total erythrocyte count, TEC; haemoglobin, Hb; packed cell volume PCV; mean corpuscular volume , MCV; mean corpuscular haemoglobin, MCH; mean corpuscular haemoglobin concentration MCHC, red cell distribution width, RDW), the white ones (total leukocyts count,TLC; lymphocytes, monocytes, granulocytes) and platelet (platelet count, PLT; platlet distribution width, PDW; mean platelet volume, MPV; Platelet crit, PCT) were made using the Automatic Hematology Analyzer. The mean and standard error values observed in the study were TEC 6.99 ± 0.18 103/µl, Hb 10 ± 0.19g/dl, PCV 33.03 ± 0.44%, MCV 48.92 ± 1.06 fl, MCH 14.53 ± 0.26 pg, MCHC 29.99 ± 0.46 g/dl, RDW 18.44 ± 0.76%, TLC 10.24 ± 0.37 103/µl, lymphocytes 63.22 ± 1.34 %, monocytes 13.66 ± 0.39 %, granulocytes 29.42 ± 1.06 %, PLT 259.9 ± 13.05 103/µl, MPV 6.18 ± 0.11 fl, PDW 16.97 ± 0.15 % and PCT 0.17 ± 0.009 %. Haematological parameters of calves of Kosali cattle were within the physiological range as compared to other breeds of cattle, while slight deviations were observed for certain parameters. These results may be a better understanding of the haematological indicators for estimating the physiological status of calves of Kosali cattle for further investigation, diagnosis of different ailments and academic purposes.
