CP, crude protein; Values for SID were calculated by correcting the AID values with the basal endogenous losses (IAA_end). IAA_end (g/kg DM intake) averaged as CP, 21.24; Arg, 1.96; His, 0.23; Ile, 0.56; Leu, 0.43; Lys, 0.08; Met, 0.15; Phe, 0.48; Thr, 0.80; Trp, 0.19; Val, 0.6; Ala, 1.01; Asp, 0.77; Cys, 0.04; Glu,1.03; Gly, 1.02; Pro, 6.39; Ser, 0.64; Tyr, 0.63. ^a,b,c,d,e Means that values in the same row with no letter or the same letter are not different at p < 0.05.
