The feed ingredient ａnd diet samples were analyzed following AOAC (2006) procedures for CP, ether extract, crude fiber, ａnd Ca ａnd P concentration. The AA profile of ingredients ａnd diets were analyzed using HPLC (Hitachi L-8800 AA Analyzer; Hitachi, Tokyo, Japan) after one of 3 hydrolysis procedures (AOAC, 2006). Most of the AA were determined after acid hydrolysis in 6 N HCl at 110 °C for 24 h. For the determination of S-containing AA, the oxidation process was performed before the acid hydrolysis using performic acid. The analysis of Trp was performed after alkaline hydrolysis. The SUN concentration was determined using a biochemical analytical instrument (Byer Diagnostics Manufacturing Ltd., Dublin, Ireland). The plasma cortisol was determined by using an Enzyme-Linked Immuno-Sorbent Assay kit for porcine cortisoldetermination (Hengyuan Bio-technology, Shanghai,China). The intra-assay coefficient of variation was 10%.
