A study of effect of dietary supplementation levels of yeast fermented broken rice (YFBR) of Ac chicken was carried out to evaluate growth performance, carcass characteristics and intestinal health. One hundred fifty Ac chicken at 15 days of age with average live weight of 96.2±0.69 g/bird were arranged in a completely randomized design with five treatments and three replicates. The treatments were (YFBR) supplementation levels of 0, 1.5, 3, 4.5and 6% (DM basis) of the concentrate diets, corresponding to YFBR0, YFBR1.5, YFBR3, YFBR4.5 and YFBR6 treatments with 10 chicken per experimental unit. The results of the experiment showed that the DM, CP, EE and ME intakes were significantly lower (psupplemented FBRY6 than the remains. The daily weight gain and final weight were significantly improved when the birds supplemented YFBR, and the highest results were found for the YFBR4.5 treatment (pcarcass, breast meat and thigh meat weights for the birds supplemented YFBR diets were significantly higher (Pwas that at level of 4.5% yeast fermented broken rice added in the concentrate diet gave the higher growth performance and carcass values, better FCR and decreased density of E. coliand C. perfringensin the excreta leading to enhancing intestinal health of Ac chicken.
