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.
