Effect of rice distillers dried grains with solubles and rice gluten meal along with enzyme supplementation on the growth performance, nutrient utilization, production efficiency, and cost economics of broiler chicken production

Abstract

An experiment was conducted to evaluate the effect of feeding rice distillers dried grains with solubles (rDDGS) and rice gluten meal (RGM) combination with enzyme supplementation on the production performance of broiler chickens. The experimental diets consisted of the following: T1 (no rDDGS/RGM/enzyme), T2 (no rDDGS/RGM, multienzyme), T3 (12.5% rDDGS, 15.0% RGM, no enzyme), T4 (12.5% rDDGS, 15.0% RGM, protease enzyme), T5 (10.0% rDDGS, 12.5% RGM, no enzyme), and T6 (10.0% rDDGS, 12.5% RGM, protease enzyme). Each treatment was assigned 6 replicate groups of birds randomly with 8 birds in each group (48 birds/ treatment). The results revealed the poor growth performance, nutrient utilization, and production efficiency of birds fed a combination of 12.5% rDDGS and 15.0% RGM, followed by the combination of 10.0% rDDGS and 12.5% RGM compared to birds fed no rDDGS and RGM. Enzyme supplementation resulted in significantly (P < 0.01) better growth performance, nutrient utilization, and production efficiency of the birds compared to unsupplemented birds. It was concluded that inclusion of a combination of 10.0% rDDGS and 12.5% RGM as a replacement for soybean, along with dietary enzyme supplementation, can be a potential nutritional strategy for economic broiler chicken production.
