^a-fValues within a row lacking a common superscript letter are different (P < 0.05).

¹Data are least squares means of 8 observations for each treatment.

²Standardized ileal digestibility values were calculated by correcting values for apparent ileal digestibility for the basal ileal endogenous losses. Basal ileal endogenous losses were determined as (g/kg DMI): CP, 23.23; Arg, 0.74; His, 0.22; Ile, 0.38; Leu, 0.62; Lys, 0.32; Met, 0.10; Phe, 0.44; Thr, 0.79; Trp, 0.18; Val, 0.52; Ala, 0.73; Asp, 0.93; Cys, 0.30; Glu, 1.09; Gly, 2.21; Pro, 7.95; and Ser, 0.76.

³FFRB = full fat rice bran; DFRB = defatted rice bran.
