Abstract

In the current study, various haematological and biochemical parameters of chickens were evaluated following an oral administration of resin extract from Commiphora swynnertonii. Sixty chickens (8 months old) were randomly assigned into 5 groups (n=12): G1 served as a negative control, that is, chickens received normal saline only, while G2 to G5 chickens were given different doses of the resin extract orally for 14 consecutive days. Results revealed no signs of sickness or death in groups G1, G2 and G3 throughout the experimental period of 28 days. The body weights of chickens in G2, G3, G4 and G5 decreased significantly in a dose dependent manner from day 3 of treatment with the resin. The resin administration did not affected packed cell volume (PCV), total white blood cell (WBC) count, differential WBC count (heterophils and eosinophils). However, haemoglobin (Hb), total red blood cell (RBC) count, mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) decreased significantly (P < 0.05) with increasing concentration of the resin. Significant dose dependent reduction (P < 0.01) in plasma glucose and total cholesterol was observed. Levels of total protein, albumin and globulin in the resin-treated groups were not significantly affected. In the current study, liver transaminases (alanine transaminase (ALT) and aspartate aminotransferase (AST)) levels increased slightly to a maximum peak by day 21-post treatment. It is concluded that administration of the resin extract in chickens caused no undesirable effects at lower doses, but with increased doses signs of toxicity were evident. It is therefore suggested that, before the resin extract can be used for veterinary or medical purposes, safety margin must be established for each animal species in question.
