Data are means of 6 observations per treatment.
Values for SID are calculated by correcting the apparent ileal digestibility (AID) values with the basal endogenous losses. Basal endogenous losses (g/kg DM intake) averaged as CP, 11.98; Trp, 0.09; Cys, 0.20; Asp, 0.75; Arg, 0.31; His, 0.20; Gly, 1.20; Ile, 0.33; Leu, 0.59; Lys, 0.46; Met, 0.10; Phe, 0.20; Thr, 0.43; Ser, 0.40; Glu, 1.01; Trp, 0.08; Val, 0.53; Ala, 0.64; Tyr, 0.22.
a–cWithin a row, means followed by the same or no superscript letter are not different (P > 0.05); multiple comparison correction is used by Tukey.
