EFFECT OF BOILING DURATIONS OF ROSELLE SEED ON THE HAEMATOLOGY PROFILE OF BROILER CHICKENS

Résumé

A study was conducted to evaluate the effect of boiling durations of roselle seed on the haematological profile of broiler chickens. There were six dietary treatments groups; T1 served as the control diet (raw), while T2, T3, T4, T5, T6 and T7 diets containing Roselle seeds boiled for 20min, 30min, 40min, 50min and 60min respectively. Parameter measured were Pack cell volume (PCV), Red blood cells (RBC), White blood cell (WBC), Haemoglobin (Hb), Total blood protein (TP) and differential blood count), mean corpuscular volume (MCV), mean corpuscular heamoglobin (MCH) and mean corpuscular heamoglobin concentration (MCHC). There were no significant (P>0.05) differences across the dietary treatments for PCV, total protein, white blood cell, red blood cell, haemoglobin, lymphocytes, monocytes, mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration with the exception of neutrophils which differ significantly (P<0.05). The haematological values were within the reference range for healthy birds. It was therefore concluded that boiling duration of roselle seed has no adverse effects on the health status of the broiler chickens.
