摘要: 对108只野生东方田鼠(Microtus fortis Büchner)进行了驯育,并观察其习性和繁殖情况。经过2年,东方田鼠已适应实验鼠类常规饲养环境(温度18~26℃,相对湿度60%~70%),生长发育良好,繁殖产仔日趋正常;75~80日龄性成熟,初配日龄为85~90日龄,孕期为21d;平均每胎产仔3.7只,仔鼠成活率68.75%。

Abstract: Microtus fortis Buchner is the only kind of rodent resistant to Schistosoma jap-onica. Through 2 years domestication, the animals(M. fortis Buchner) captured from Yueyang area in Hunan province had basically adapted to the conventional breeding environment of laboratory rodents (ambient temperature, 18-26℃; relative humidi-ty, 60%—70%), grown and developed well, and gradually regained its' normal reproductivity. Its' sexual maturity was at 75-80 days old.The first mating was at 85—90 days old, the gestation length was 21 days, the average litter size 3.7, and the weaning rate 68.75%.
