¹The analyzed xylanase activities for the PC and NC diet were 187 and 160 U of xylanase per kilogram of diet, respectively. The xylanase activities for the NC diets with multi-enzyme at 0.5 or 1.0 g/kg of diet were 1,037 and 2,113 U of xylanase per kilogram of diet, respectively.

²PC diet was a corn–SBM-based diet, which was formulated to be adequate in all nutrients except for Ca and digestible P, which were lower than NRC (2012) recommendations for grower pigs by 0.13 and 0.17 percentage points.

³Negative control diet was the same as the PC diet except that it was lower in NE by 75 kcal/kg, and standardized ileal digestible AA content by a mean of 3%; this was achieved by a partial replacement of corn and SBM and a complete replacement of soybean oil and monocalcium phosphate with 25% corn DDGS and 3% soybean hulls.

⁴NSP = nonstarch polysaccharides.
