Apparent digestibility values were standardized using the following basal ileal endogenous flow values (g/kg DM intake), determined by the feeding nitrogen-free diet: crude protein, 10.8; Arg, 0.44; His, 0.15; Ile, 0.37; Leu, 0.60; Lys, 0.39; Met, 0.15; Phe, 0.42; Thr, 0.52; Trp, 0.13; Val, 0.47; Ala, 0.40; Asp, 0.77; Cys, 0.22; Glu, 0.98; Gly, 0.42; Pro, 0.45; and Ser, 0.52.

Each value represents the mean of six replicates (six birds per replicate).
