^aDiet: CO = group fed a standard lactating sows’ diet; Arg = group was fed the standard lactating sows’ diet plus 22.5 g/d/sow of L-Arg; BCAA = group was fed the standard lactating sows’ diet plus L-Val, L-Ile and L-Leu at 9, 4.5 and 9 g/d/sow; BCAA + Arg = group was fed the standard lactating sows’ diet plus L-Val, L-Ile, L-Leu and L-Arg at 9, 4.5, 9 and 22.5 g/d/sow
