The present study was conducted to improve the nutritional value of defatted rice polishing by treating it with certain chemicals and physical methods. 108 male broiler chicks of approximately similar weight were selected out of 220- day-old male broiler chicks priory fed on commercial diets for 7 days settlement period. Seven experimental diets viz. commercial diet; HCl treated DFRP; HCl treated and extruded; H2O2 treated; H2O2 treated and extruded; raw DFRP and protein free diet were incorporated into 7 major groups i.e. A, B, C, D, E, F and G. The groups B to F were having 18 chicks each. Each group was further divided into 2 sub-groups having 9 chicks each and each sub group was dispersed into three replicates, having three chicks each. The group A and G having 9 chicks each and divided into three replicate of 3 chicks each. All sub- groups of groups fed on different experimental diets included differently treated rice polishing at 10% and 20% levels respectively. Overall results showed that weight gain (282g), Feed consumed (387), FCR (1.37), Protein efficiency ratio (3.64), Protein digestibility percentage (93.5), Net protein utilization (59.5), biological value (63.6) were significantly higher than other treatments. It might be due to the fact that H2O2 treatment proved better to eliminate anti-nutritional factors i.e. Phytates, hemoglutinin etc. from DFRP and convert indigestible fiber into digestible form by breaking ligno-cellulose bond.
