Haematological analysis
Blood percentage (Hb) and red blood cell (RBC) levels were
determined using Sahli`s and Alexander and Griffith (1993a)
methods respectively. Westergreen`s method was used for
erythrocyte sedimentation rate (ESR), Counting chamber and slide
methods were used for white blood cell total count (WBC) and
differential counts respectively. Haematocrit method (Jones, 1961)
was used for packed cell volume (PCV) whereas, mean corpuscular
volume (MCV), mean corpuscular haemoglobin (MCH) and mean
corpuscular haemoglobin concentration (MCHC), were
determined as described by Alexander and Griffith (1993b).
