[ Objective] To observe sub-chronic toxicity of Tephrosia canadida DC. in mice and thus to evaluate their safety to be used as protein feed resources. [ Methed]Sixty-four 6-week-old healthy Kunming mice weighing about 25 g were randomly divided into four groups （ n = 16）, half male and half female. Mass ratios of basic diet to leaf meal of Tephrosia canadida DC. in group A, group B, group C and group D were 10：0, 4：1, 3：2 and 2：3, respectively. After 35-d feeding, the effects of Tephrosia canadida DC. on growth, blood and organs of mice were observed. [ Resultl Dudng the trial, all mice had normal activities, and no death and no abnormal blood index were observed. All organs of the mice in the experimental groups had no visible pathological lesion, and organ indexes had no significant difference between the experimental groups and the control group. Except that slightly abnormal histological changes appeared in liver and kidney of the mice in the group C and D, no histological change was ob- served in other organs of the experimental mice. [ Conclusion] Tephrosia canadida DC. have no adverse effects on mice, which provides a refer- ence for research about their safety in feed of other animals.
