¹Data are least square means of 6 observations.

²Values for SID were calculated by correcting the values for AID for basal ileal endogenous losses (n = 6). Basal ileal endogenous losses were determined (g/kg DMI) as CP, 16.14; Arg, 0.57; His, 0.18; Ile, 0.31; Leu, 0.49; Lys, 0.45; Met, 0.09; Phe, 0.32; Thr, 0.64; Trp, 0.11; Val, 0.62; Ala, 0.54; Asp, 0.77; Cys, 0.25; Glu, 0.86; Gly, 1.61; Ser, 0.52; and Tyr, 0.23.
