This study was conducted to examine the haematological and some serum biochemical indices of growing Isa cockerels fed diets supplemented with Azollaturmeric mixture. One hundred and twenty (120) four weeks old Isa white cockerels were divided into four groups with three replicates, each of ten birds in a completely randomized design. Treatment 1 was fed basal diet without Azollaturmeric mixture (ATMP), treatment 2, 3 and 4 were fed basal diets supplemented with ATMP at levels 5, 10 and 15% respectively. Proximate analysis shows that Azolla powder contained 22.51% crude protein, 3.53% ether extracts, 14.13% ash, 18.15% crude fibre and 37.88% nitrogen free extract while turmeric powder contained 9.14% crude protein, 2.40% ether extracts, 8.69% ash, 4.10% crude fibre and 69.10% nitrogen free extracts. The basal diet was formulated to meet the nutritional requirements of birds according to NRC (1994). All the hematological parameters evaluated : Pack cell volume (PCV), Haemoglobin (Hb), White blood cell (WBC), Red blood cell (RBC), Mean corpuscular haemoglobin concentration (MCHC), Mean corpuscular volume (MCV), Mean corpuscular haemoglobin (MCH) were not significantly(P>0.05) affected by the inclusion of ATMP. However, there were no significant (P>0.05) differences among all treatment groups in the values of total protein, albumin, globulin, alkaline phosphatase, uric acid, creatinine, SGPT and SGOT throughout the experiment which lasted for 90days. It was concluded that Azolla -turmeric mixture could be added up to 15% in the diet growing cockerels without any adverse effects on their blood profile.
