Comparative Evaluation of Hematological Parameters in Hardhenu, Hariana and Sahiwal Cattle at Different Age Groups

Study comprising seventy two cattle of three breeds/strain viz. Hardhenu crossbred strain, Hariana and Sahiwal breeds were carried out to evaluate the differences in hematological parameters. Each group consisted of 24 animals of different age groups i.e. 0-1 year, 1-2 year, 2-3 year and >3 year. The various hematological parameters i.e. hemoglobin (Hb), total leucocyte count (TLC), differential leucocyte count (DLC), packed cell volume (PCV), total erythrocyte count (TEC), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and mean corpuscular volume (MCV) in all the three breeds/strain at different ages were studied. Significantly higher Hb % especially at the age of 2-3 year was observed in Sahiwal animals over other 2 breed groups. Well known feature of higher disease resistance of Hariana breed was supported by significantly higher TLC as compared to other two breeds. The age wise significant difference was observed for group 1-2 years and, >3 years while Hariana showing high count. The lymphocyte, monocyte, neutrophils, Hct, TEC, MCH and MCHC were comparable in all the three breeds/strain.
