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

^xyz Within a row means without a common superscript show tendency to differ (P < 0.10).

^*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.

^**Standard error of the means.

^***Average carcass gain value from first pigs loading (11 wk) to last pigs loading (14 wk).

^†Feed cost x total feed consumption from initial to last loading (14 wk).

^††Facility cost at $0.10/hd/d (until the last loading; 14 wk).

^†††Income over feed cost = carcass gain value – total feed cost.

^‡Income over feed and facility cost = IOFC – facility cost.
