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;
A cDDGS diet with SID BCAA:Lys targeted for the growing phase for overall experimental period;
A cDDGS diet with SID BCAA:Lys targeted for the finishing phase for overall experimental period;
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.
