  1. a Abbreviations: CS corn-soybean meal based diet, DDGS corn-soybean meal-distillers dried grains based diet, DDC dehulled, degermed corn-soybean meal based diet. For Phase-1, ADFI from d 1 to 14 was 2.94, 2.79, and 2.66 kg (SE = 0.07 kg) for pigs fed the DDC, CS, and DDGS diets, respectively. For Phase-2, ADFI from d 14 to 28 was 2.91, 2.84, and 2.63 kg (SE = 0.21 kg) for pigs fed the DDC, CS, and DDGS diets, respectively
  2. bCollection day following change from Phase-1 to Phase-2 diet, with d 14 representing the first day of the diet containing the Ti marker was fed
  3. cLOQ = limit of quantitation; 6 mg Ti/kg. with ½ LOQ used for statistical analysis
