Effects of baicalin on the protection of piglets against G. parasuis challenge. Before G. parasuis challenge, the piglets in the EP group were injected intraperitoneally with EP, and the piglets in the FM group were injected intramuscularly with FM. After pretreatment with baicalin at concentrations of 25–100 mg/kg BW for 30 min, the piglets were challenged with 1 × 10⁹ CFU of G. parasuis strain SH0165. The mortality of the piglets was recorded. G. parasuis: HPS (the infection group); 25–100: the piglets were injected intramuscularly with baicalin at 25 mg/kg BW (treatment group 1), 50 mg/kg BW (treatment group 2), or 100 mg/kg BW (treatment group 3).
