一种醇类雄性不育剂对高原鼠兔精子的影响

高原鼠兔(Ochotona curzoniae),隶属于兔形目(Lagomorpha),鼠兔科(Ochotonidae),又名黑唇鼠兔,主要分布于青藏高原及其边缘地带,栖息于海拔4 000 m左右的宽谷草原草甸区(王酉之和胡锦矗,1999),在食物链中扮演着重要的角色,是青藏高原草原生态系统中的关键物种.近年来随着全球变暖、若尔盖湿地水位下降等因素,高原鼠兔在若尔盖湿地繁殖加快,高原鼠兔成了危害草原生态系统的主要害兽(刘少英,2005).1997年,若尔盖湿地高原鼠兔平均种群密度为6 400只/km2(刘少英和冉江洪,1999),据我们2007年的调查显示,平均种群数量上升到25 000只/km2,控制鼠兔数量迫在眉睫.

Effects of the male sterile preparation(MSP-1) on plateau pika(Ochotona curzoniae) sperm

To investigate the effects of the Male Sterile Preparation (MSP-1),an alcoholic male chemosterilant,on sperm count and sperm motility of the male plateau pika,40 adult male plateau pikas were randomly divided into 4 groups (n=10/group) that received 0,20,40 or 60 mg/kg bw of MSP-1 (ig). The weight of body,testis,epididymis and the count,motility,malformation rate of sperm were analyzed after 19 days. The body,testis and epididymis weights were not significantly different (P>0.05) at any dose levels when com...
