摘　　要：在普通的饲养条件下，对昆明小鼠进行了体重增长、脏器重量及生产性能的研究。结果表明：昆明小鼠平均产仔数13．72只／胎，平均初生重1．89g、乳仔成活率98．41％。体重增长快，日增重：2周内0．665g；2周至6周，雄鼠0．7g，雌鼠0559；7周至10周，雄鼠0．38g，雌鼠0．32g。雌鼠生产胎间隔：平均23．33d.Body weight, weight of internal organs, and reproductive ability of conventional KM micewas studied. The results demonstrated that the average product number of mice was 13. 72 at onelitter, the average weight of mice was 1. 89 grams at birth, and the survival rate of sucking micewas 98. 41 %. The KM mice during the first 2 weeks after birth grew rapidly, it increased 0. 665grams a doy. From the second to the sixth week, the male and female mice increased 0. 7 and 0.55 grams respectively. From the seventh to the tenth week, the male and female mice increased0. 38 and 0. 32 grams respectively. The average number of days between litters were 23. 33.
