Administration dose, formal trial grouping and group interval were determined in pre-trial using incremental method. Formal test was performed using simplified karber＇s method. Changes in sign of mice after ad- ministration were observed; the mortality rate was statistically calculated, and the time of death was recorded; the median lethal dose （LD50） and 95% confidence limit of oxyclozanide suspension were calculated. The results showed the LD50 of oxyclozanide suspension in mice by oral administration was 1. 679 g/kg, and the 95% confidence interval was 1. 439 - 1. 947 g/kg. According to toxicity grading of chemicals, oxyclozanide suspension was low toxic substance.展开更多
