FCGM = fermented corn germ meal; GE = gross energy; CP = crude protein; CF = crude fiber; NDF = neutral detergent fiber; ADF = acid detergent fiber; SID = standard ileal digestible.

¹FCGM0, FCGM10, FCGM20 and FCGM30 diets were made by substituting fermented corn germ meal for 0%, 10%, 20% and 30% soybean meal.

²The vitamin and trace element premix compositions were the same as those in Exp. 1.

³The values were calculated according to feed composition and NRC (2012). Metabolizable energy and digestible amino acids of soybean meal and FCGM were obtained in Exp. 1 and 2.
