At the end of the experiment, digestibility of dry matter was increased in broiler chickens fed RY1500 (linear, P=0.011) and PC (P=0.035) diets by 3.7 and 3.9%, respectively, compared with NC diet. The digestibility of gross energy was increased (linear, P=0.019) by 4.4% when broiler chickens were fed RY1500 diet compared with those fed NC diet. Yellowness of breast muscle (linear, P=0.003) was increased by 10.7% in broiler chickens fed RY1500 diet compared with the NC group. However, there was no significant influence on growth performance, relative organ weight, and excreta microflora. In conclusion, the results from this study demonstrated that nutrient digestibility and meat quality were improved slightly in the broiler chickens supplemented with RY.
