Abstract

The main objective of the study was to confirm whether a specific and constant interrelationship exists between total erythrocyte count (TEC) and hemoglobin (Hb) concentration in Cholistani cattle blood and to navigate the potential of TEC for estimating Hb level in Cholistani cattle (n = 264) grouped as per gender (males, n = 122; females, n = 142) and age (young, n = 140; adults, n = 124). The TEC and Hb (HbD) estimation was carried out through veterinary hematology analyzer. The Hb was also calculated as TEC × 3 and was termed as HbC. Linear regression was implied, and accordingly, scatterplots were drawn between TEC, HbD, HbC, and corrected Hb (CHB). The regression prediction equation hence attained was used to deduce corrected hemoglobin (CHb). A significant (P ≤ 0.05) difference was noticed between HbD and HbC. A non-significant (P ≥ 0.05) difference was noticed, however, between HbD and CHb. Tests of level of agreement indicated a higher Cronbach's alpha and intraclass correlation coefficient (0.682 for average measures) for HbD and CHb as compared to that for HbD and HbC (0.559 for average measures). A convention of Hb concentration as three times of TEC (× 3) is not valid for Cholistani cattle. A different pen-side hematological formula, i.e., Hb (g/dL) = 0.66(TEC) + 6.1, however, provides a better estimate of Hb from the TEC in cattle blood. Using hemocytometry for TEC in the field, all the stakeholders associated with veterinary research, academics, and practice may benefit from this formula in resource-poor countries.
