This experiment was conducted to evaluate the anti-nutritional factors, hematological and serum parameters of broiler chickens fed Rice Milling Waste (RMW) as a replacement for maize. The anti-nutritional factors were determined, also eleven experimental diets each were formulated to contain RMW as replacement for maize at 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%. Around 307 old chicks’ old chicks were allocated to the 11 dietary treatments each having 3 replicate pens with 10 birds per pen in a Completely Randomized Design (CRD). Feed and water were provided ad libitum for 6 weeks. Data were collected on the hematology and serum biochemistry of broiler chickens with emphasis on serum enzymes which were analyzed using ANOVA with a (p<0.05) level of significance. Result from anti-nutritional factors showed that rice milling waste were suitable as feed ingredient and as well would not hamper physiological response, hinder nutrient utilization and absorption of RMW and other ingredients present in the diet. The hematological indices and serum profile showed that the values were within the normal physiological range except for Packed Cell Volume (PCV) of broiler chickens fed 100% RMW (47.83%) which had a value above the normal range, a condition known as polycythemia, a disease state in which PCV is elevated which might be due to an increase in the number of RBC or to a decrease in the volume of plasma. Thus, the inclusion of RMW in diet of broiler chickens as a replacement for maize improved nutrient utilization and economic value. It can therefore be recommended that RMW can be used to replace maize between 10%-40% in the diets of broiler chickens.
