The studies on some hematological parameters on cattle egret (Bubulcus ibis) in Maiduguri, Borno state Nigeria

This study was carried out to establish baseline hematological values for the cattle egret in Maiduguri, Nigeria. Twenty (20) birds Cattle egret (Bubulcus ibis) were used for this study; they were caught during the rainy season within University of Maiduguri, Nigeria. Blood samples were collected through cardiac puncture and blood collected into the heparinized tubes and taken to the laboratory for analysis. The parked cell volume (PCV), Hemoglobin concentration (Hb), red blood cell (RBC) and differential leucocytes counts were determined. The values obtained were RBC (106mm3) = 2.58 ± 0.76, PCV (%) = 39.45 ± 0.34, Hb g/dl = 8.24 ± 0.84, MCH (pg) = 30.42 ± 2.70, MCHC (g/dl) = 24.14 ± 0.32, MCV (fl) = 160.00 ± 0.60, heterophils (%) = 38.62 ± 0.21, Lymphocytes (%) = 46.00 ± 1.26, Basophils (%) = 0.62 ± 0.10, Monocytes (%) = 4.20 ± 0.10, Eosinophils (%) = 3.40 ± 0.20 and WBC (x 109/L) = 0.75 ± 0.28. The hematological data obtained in this study can be considered preliminary reference values, which are particularly important for future research in these birds and other avian species in Maiduguri.
