^abc Within a row means without a common superscript differ (P < 0.05).

^*Positive control (PC): a corn–SBM based diet with SID BCAA:Lys of PIC (2020) for the overall experimental period; negative control (NC): a cDDGS diet with SID BCAA:Lys of PIC (2020) for the overall experimental period; Grow: a cDDGS diet with SID BCAA:Lys targeted for the growing phase for the overall experimental period; Finish: a cDDGS diet with SID BCAA:Lys targeted for the finishing phase for the overall experimental period; Grow–Finish: a cDDGS diet with SID BCAA:Lys targeted for the growing phase for phases 1 and 2 and SID BCAA:Lys targeted for the finishing phase for phases 3 and 4.
