玩具对小鼠生长发育及繁殖性能的影响

目的：探讨玩具对实验小鼠生长发育及繁殖性能的影响。方法选取7-8周龄ICR小鼠，在生产过程中加入玩具进行干预，观测其对小鼠生长发育及繁殖性能方面指标的影响。结果除产仔数外，实验组各项繁殖性能指标均优于对照组，且差异显著（ P ＜0.05）。并且随干预时间延长，差异的显著性有进一步增加的趋势。实验组小鼠的生长发育水平相比于对照组有明显变化，且表现出有随干预时间延长而产生差异的趋势，但目前尚无统计意义（ P ＞0.05）。结论玩具对ICR小鼠的生长发育及繁殖性能有一定程度的积极影响，在小鼠的生产和饲育过程中值得借鉴。

Effects of enrichment with toys on growing development and reproductive performance of mice

Objective To study the effects of toys for laboratory animals on reproductive performance and growing development of experimental mice.Methods ICR mice were fed with toys, the informations of reproductive performance and growing development were recorded.Results All the data of reproductive performance of the test group were higher than the control group except the number of newborn mice, and showed significant difference （ P〈0.05 ） .The data of growing development of the test group were higher than the control group too, but showed no significant difference （ P 〉0.05）.Conclusion Toys for laboratory animals have good effects on reproductive performance and growing development of mice, and suggested to be used into the process of experimental mice raising.
