Optimal branched-chain amino acid ratio improves cell proliferation and protein metabolism of porcine enterocytesin in vivo and in vitro

- The optimal branched-chain amino acid (BCAA) ratio was 1:0.75:0.75 in vivo and 1:0.25:0.25 in vitro.
- The optimal BCAA ratio could improve intestinal morphology and increase cell proliferation.
- The optimal BCAA ratio could promote amino acid absorption and intestinal protein turnover.
