The effects of the saponin on body weight increase (a), spleen index (b), thymus index (c) and bacterial count (d) in liver of chicks infected by Escherichia coli and Staphylococcus aureus. Chicks in each group were injected intraperitoneally by 0.2 ml (1 × 108 CFU/ml) of E. coli or S. aureus suspension except normal group, 10 h later administered with feed containing erythromycin (50 mg/kg) or the saponin (50 mg/kg in low dose, 250 mg/kg in middle dose, 500 mg/kg in high dose) respectively for consecutive 3 d. The chicks were weighed, monitored for 14 d. a, p < 0.01, compared with negative group; b, p < 0.01, compared with erythromycin group. Nor: normal group; Neg: negative group; LDS: low dose of the saponin; MDS: middle dose of the saponin; HDS: high dose of the saponin; Ery: erythromycin; LDSE: low dose of the saponin + erythromycin; MDSE: middle dose of the saponin + erythromycin; HDSE: high dose of the saponin + erythromycin
