¹ CT = corn-miscellaneous meal diet; NSPEC = non-starch polysaccharide enzymes cocktail diet. The optimal NSP enzyme cocktail was 1002 U/kg cellulase, 18,076 U/kg xylanase, 1376 U/kg β-glucanase, 14,765 U/kg β-mannanase, 337 U/kg α-galactosidase and 138 U/kg pectinase in the corn-miscellaneous meal diet. ² The premix provided the following per kg of diets: Vitamin A 8250 IU, Vitamin D₃ 825 IU, Vitamin E 40 IU, Vitamin K₃ 4 mg, biotin 0.2 mg, chloride 600 mg, folic acid 2 mg, nicotinic acid 35 mg, pantothenic acid 15 mg, Vitamin B₂ 5 mg, Vitamin B₁ 1 mg, Vitamin B₆ 2 mg, Vitamin B₁₂ 25 μg, CU as copper sulfate 50 mg, I as potassium iodide 0.5 mg, as ferrous sulfate 80 mg, as manganese sulfate 25 mg, as sodium selenite 0.15 mg, as zinc sulfate 100 mg. ³ DM = dry matter; GE = gross energy; CP = crude protein; NDF = neutral detergent fiber; ADF = acid detergent fiber; AA = amino acid.
