1Control, diet was mixed with water to 25% DM before feeding.
2XBNS, a complete diet containing DDGS and enzymes (xylanases and β-glucanase, XB) were mixed with water (25% DM).
3XBS, DDGS was steeped with enzymes XB (3 to 10 d at 40 °C), then it was mixed with the basal diet and more water (25% DM) immediately before feeding.
