Neem leaf meal (NLM) and pawpaw leaf meal (PLM) were prepared by air drying for 10 days. The birds were assigned to different treatment diets supplemented with the leaf meals and prepared as follows; T1 (0% NLM + PLM), T2 (0.5% NLM + PLM), T3 (1% NLM + PLM) and T4 (2% NLM + PLM). Except for packed cell volume (PVC), monophils, cosinophils and platelets, there were significant (P<0.05) differences in white blood cell (WBC), lymphocyte, haemoglobin (Hb) heterophils of birds on the treatment diets compared with the control. While total serum protein (TSP) and globulin in the control recorded significant (P<0.05) lower values compared with treatment 2, 3 and 4. Albumin, cholesterol, Aspertate, Transaminase (AST), Alanine Transaminace (ALT), Alanine phosphatase (ALP) showed no significant (P>0.05) differences.en-USMonophils, eosinophils ‘and plateletsArticle
