  2. 1In parentheses: standardized ileal digestible (SID) content of individual AA (g/kg DM). The contents of SID Lys, Met, Thr, Ile, Leu, Val, His, Phe, and Cys were calculated based on feed ingredient compositions by DPRC (2013), and the SID contents of Trp, Ala, Asp, Glu, Gly, Pro, Ser, Tyr and Arg were calculated from feed ingredient compositions by NRC (2012)
