摘要:
目的  通过对清洁级Long Evans 大鼠生长发育及繁殖性能的主要指标测定,为其大量生产和使用提供基础数据。 方法  在屏障设施(SPF级)内饲养40对清洁级Long Evans 大鼠种鼠 ,采用一雌一雄间隔同居方式交配5胎,测定其生长发育及繁殖性能的主要指标;从第2胎中选择60只离乳仔鼠,雌雄各半,间隔5 d称重,描记生长曲线。 结果  以第2胎的产仔数、初生窝质量、离乳窝质量和离乳鼠质量最高,第5胎最低;描记的生长曲线与Taconic公司公布的相似。 结论  Long Evans 大鼠以连续繁殖4胎为宜,第2胎最适合留种。
Abstract:
Objective    To study the growth and development as well as reproductive capacity of CL Long Evans rats.     Methods    Eighty CL Long Evans rats(80 days old)were bred in a barrier system. A monogamous mating system is used to reproduce 5 litters. Their main indexes of growth and reproduction were determined. The body weight gain of 60 second litter rats were analyzed from day 20 to 100.     Results    The number and weight of the fetus, the weaning time weight per cote and per litter in the second litter were the highest, and the fifth litter was the lowest. The growth and development curve was the same as that announced by Taconic.     Conclusion    Long Evans rats have been confirmed suitable for continual reproduction for 4 litters and the second litter is the best one for mating.
