  1. a,bMeans without a common superscript in the same row differ; pairwise comparison.
  2. 1Data are means of 8 observations. Values for standardized ileal digestibility were calculated by correcting apparent ileal digestibility values for basal endogenous losses (g/kg of DMI), which were determined by feeding pigs a N-free diet; CP, 13.84; Arg, 0.47; His, 0.14; Ile, 0.26; Leu, 0.42; Lys, 0.32; Met, 0.08; Phe, 0.27; Thr, 0.48; Trp, 0.09; Val, 0.39; Ala, 0.55; Asp, 0.65; Cys, 0.14; Glu, 0.78; Gly, 1.20; Pro, 4.60; Ser, 0.37; Tyr, 0.20.
  3. 2Orthogonal contrast comparing conventional DDGS and the 2 sources of low-fat DDGS with additional oil.
