| 摘 要： | 目的获取IRM-2近交系小鼠的生殖生长特性的有关资料.方法ICR/JCL为母本,以615小鼠为父本杂交选育的近交系小鼠IRM-2,现已繁育至第38代.经过对其生殖、生长特性的观察和测定来取得相关资料.结果该小鼠出生后45d性成熟;繁殖能力强,平均每窝产仔数为8只以上,最高可达15只;生长发育迅速,出生后60d体重可达28g以上,各脏器重均高于亲代鼠.结论从各项指标来看,IRM-2小鼠是优良的近交品系小鼠.

| Abstract: | Objective\ To obtain the information of characteristics of reproduction and growth of IRM-2 inbred strain mouse.Methods\ The growth and reproduction performances including litter size, weanling rate,body length, body weight and organ weight were investigated in the IRM-2 inbred strain mouse.Results\ The reproductive capacity of IRM-2 mouse was stronger than the parental strain 615 mouse,for litter size the former was 8.5 and the latter 6.5. The weanling rate observed in IRM-2 strain was 100% and the longest life span was over 39 months. The mean body weight for male and female was 28.9g and 24.6g and the body length 9.6cm and 8.8cm at 10 weeks old,respectively,suggesting that the growing speed of IRM-2 mouse was quicker than that of parental mouse. Organ weight was higher in male than in female,except thymus.Conclusion\ The results showed that IRM-2 is a fine inbred strain mouse. |
