1Data are least square means of 6 observations per treatment.
2Values for SID were calculated by correcting the values for apparent ileal digestibility for basal ileal endogenous losses. Basal ileal endogenous losses were determined (g/kg of DMI) as CP, 12.91; 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.
3AID = apparent ileal digestibility; SID = standardized ileal digestibility.
4DDGS-HPLincolnway = high-protein distillers dried grains with solubles from Lincolnway Energy; DDGS-CV = conventional distillers dried grains with solubles.
