To investigate the effects of dietary substituent of corn distiller’s dries grains with solubles (CDDGS) on the amino acid digestibility of broiler diet, twenty four Ross broilers (6-wk-old) were used in this study. Basal diet (CP 19%, ME 3,150 kcal/kg) was formulated on corn-soybean meal and two levels of CDDGS (6 and 12%) were supplemented to basal diet. CDDDS levels (0, 6 and 12%) and 4 different sites of chicken intestines (distal end of jejunum, the middle part of the ileum, the distal end of ileum and the distal end of the rectum) were evaluated factorial as 3×4 three arrangement. Statistical analysis did not show any significant interaction between dietary treatments and the sites of the intestines in amino acid digestibility (P greater than 0.05). There was no significant difference among the sites of chicken intestines in the digestibility (P less than 0.05). The digestibility of lysine (essential amino acid) and glycine (non-essential amino acid) decreased at increasing supplementation of CDDGS (P less than 0.05). There was no significant difference on the digestibility of other amino acids studied. In conclusion, the result of this work showed that CDDGS can use as alternative resources in broiler diets.
