Haematological Characteristics of Broiler Birds Administered Neem Leaf (Azadirachta indica) and Pawpaw leaf (Carica papaya) Leaf Extracts

Abstract One hundred and twenty (120) broilers birds of Abore acere breed were used to determine the effect of pawpaw leaf and neem leaf extracts on the haematological profile of broilers birds. The chicks were randomly assigned to four treatments with 30 birds in each treatment. Each treatment was replicated three times with 10 birds per replicate in a completely randomized design (CRD). Treatment 1 received only vaccine and drugs without the leaf extract in their water, treatment 2 and 3 received 150 ml of the Neem and Pawpaw leaf extracts, respectively, and treatment 4 received 75ml of Neem extract and 75ml of pawpaw leaf extract mixed. 150ml of the extracts were all diluted into 1 litre of fresh drinking water and served to the broiler chicken. At the end of the experiment, which lasted for 7 weeks, blood sample were collected from the birds and analyzed for the haemoglobin concentration, packed cell volume, white blood cell count, and red blood cell count. Differential count was also carried out. Data obtained were subjected to analysis of variance (ANOVA). Result showed that there were no significant differences (P> 0.05) among the treatments in all the parameters tested. The study therefore concluded that 150 ml of neem leaf or pawpaw leaf extracts, or combination of the extracts may be administered to broiler birds without any deleterious effect on broilers’ haematological indices.
