Two experiments were conducted to determine the net protein utilization (NPU) and gross protein value (GPV) of rice gluten meal (RGM) and rice distillers dried grains with solubles (RDDGS). For NPU, a feeding trial of 21 days having 90 birds and 3 treatments (non-protein diet, test diet RGM and test diet RDDGS) and each treatment had 3 replicates having 10 birds in each replicate was conducted. For GPV, a feeding trial of 28 days having 120 birds and 4 treatments (depletion diet, reference diet, test diet RGM and test diet RDDGS) and each treatment had 3 replicates having 10 birds in each replicate was conducted. Results revealed that the body weight gain was higher in RGM treatment as compared to RDDGS treatment. Carcass nitrogen was also higher in RGM fed treatment as compared to RDDGS fed treatment. The NPU value of RGM (67.20) was higher than RDDGS (60.36). The weight gain in GPV experiment in RGM fed group was almost similar to RDDGS fed group but lower than reference group. Protein intake was higher in RGM fed group as compared to RDDGS fed group but almost similar in RGM fed and reference group. The GPV value of RGM (74.82) was higher than RDDGS (69.15). It was concluded that NPU and GPV value of RGM and or better than many protein sources used in broiler diets.
