Abstract

Abstract: To measure the effects of plant rodenticide on reproductive performance of Microtus fortis,the effects of plant rodenticide on serum estrogen,reproductive organ index，litter size and reproductive delay of Microtus fortis were studied by one-time gavage in laboratory.The results showed that different doses of plant rodenticide significantly increased the uterine index and changed the uterine morphology of M. fortis,but did not affect the level of serum estradiol and uterine length.The serum follicle-stimulating hormone (FSH) content and ovarian index of female voles gavaged 50 mg/kg rodenticide were significantly increased.It is showed that different doses of plant rodenticide could delay the time of first reproduction and litter size of female M. fortis,and the recovery time of reproduction in female M. fortis gavaged 10 mg/kg,25 mg/kg and 50 mg/kg groups was 11 d,22 d and 48 d longer than that of the control group,respectively.

Key words: Microtus fortis, female, plant rodenticide, reproduction
