¹Values for SID were calculated by correcting values for AID for basal ileal endogenous losses. Basal ileal endogenous losses were determined (g/kg of DMI) as CP, 16.69; Arg, 0.76; His, 0.18; Ile, 0.29; Leu, 0.49; Lys, 0.34; Met, 0.06; Phe, 0.30; Thr, 0.43; Trp, 0.09; Val, 0.39; Ala, 0.61; Asp, 0.70; Cys, 0.16; Glu, 0.88; Gly, 1.81; Ser, 0.42; and Tyr, 0.23, for lyophilized ileal digesta samples; and as CP, 10.81; Arg, 0.11; His, 0.05; Ile, 0.18; Leu, 0.28; Lys, 0.17; Met, 0.04; Phe, 0.17; Thr, 0.22; Trp, 0.05; Val, 0.25; Ala, 0.32; Asp, 0.31; Cys, 0.08; Glu, 0.48; Gly, 0.87; Ser, 0.16; and Tyr, 0.08, for oven dried ileal digesta samples.
