This work was carried out to investigate the effects of CDDGS (com distillers dried grains with solubles) colors and phytase levels on the amino acid digestibility of broilers for 7 days. One hundred eight Ross broilers were used in 9 treatment groups with a 3 × 3 factorial design as three colors of DDGSs (DDGS1, DDGS2, and DDGS3) in combination with phytase (0, 500, and 1,000 FTU/kg). The L* values of DDGS1, DDGS2, and DDGS3 were 55.2, 39.8, and 28.3; the a* values, 8.8, 7.5, and 6.1; and the b* values, 41.3, 27.1, and 15.4, respectively. The ileal digestibility of amino acids was decreased as DDGS color was dark, and increased as additive phytase level was increased in the diet. Average digestibilities of essential amino acids were 67.6~80.0%, and those of nonessential amino acids 67.4~77.3. Amino acid digestibility was low in the dark DDGS with no phytase in the diet.
