1 Postbiotic yeast cell wall-based blend (PYCW) was added to LM and HM at 0.2% in all phases to create two other dietary treatments. 2 Aflatoxin corn, aflatoxin-contaminated corn (mycotoxin concentration: 285 μg/kg of aflatoxins and 41.3 mg/kg of feed of fumonisins). 3 Deoxynivalenol (DON) corn dried distillers grains with solubles (DDGS), deoxynivalenol-contaminated corn DDGS (mycotoxin concentration: 8115 μg/kg of feed of deoxynivalenol and 401 μg/kg of feed of fumonisins). 4 Deoxynivalenol concentration is reported as sum of deoxynivalenol and its metabolites: 3-acetyl-deoxynivalenol, 15-acetyl-deoxynivalenol, and deoxynivalenol-3-glucoside. Ingredients in bold were included or not (no inclusion is represented by a dash “-“) depending on the dietary treatment. DM, dry matter; ME, metabolizable energy; SID, standard ileal digestibility; and STTD, standard total tract digestibility.
