摘　　要：为探究植物灭鼠剂对东方田鼠雌体繁殖性能的影响,通过一次性灌胃的方式研究了在不同剂量植物灭鼠剂处理条件下,雌性东方田鼠的血清雌激素、生殖器官系数、胎仔数及繁殖延迟效应.结果表明:在一定时间内,不同剂量植物灭鼠剂灌胃能显著提高雌性东方田鼠的子宫系数,但对雌性东方田鼠机体内雌二醇含量没有显著影响,50 mg/kg剂量植物灭鼠剂灌胃能显著提高东方田鼠雌体血清促卵泡刺激素含量和卵巢系数;不同剂量植物灭鼠剂灌胃均能不同程度延迟初次繁殖时间和减少胎仔数,10,25,50 mg/kg剂量组繁殖恢复时间较对照组繁殖恢复时间分别延迟11,22,48 d.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.
