  1. 1 AF corn, corn contaminated with aflatoxins at 3 mg/kg. Corn DDGS, corn distillers dried grains with solubles. DON corn DDGS, either normal or contaminated with deoxynivalenol. ME, metabolizable energy. SID, standardized ileal digestibility
  2. 2 Titanium dioxide was added at 0.5% to phase 2 diets as an external marker for assessment of apparent ileal digestibility of nutrients in feed
