¹ YCWE: yeast cell wall extract; ² Total percent combined of all family lower than 1.0% in each family. MT-: diet without aflatoxin B1 and fumonisin B1; MT+: inclusion of 180 μg/kg aflatoxin B1, 1 mg/kg deoxynivalenol, and 9 mg/kg fumonisin B1 by replacing the clean corn and clean wheat with naturally mycotoxin-contaminated corn and wheat; YC 0%: no addition of YCWE (Mycosorb A+, Alltech, Nicholasville, KY, USA); YC 0.2%: YCWE added at 2 g/kg of feed.
