日常健康检查中的噪音、振动和光干扰对小鼠繁殖性能、筑巢和皮质酮的影响。
在我们的机构,技术人员用于健康检查的技术对单独通风的笼(IVC)架上的笼子中的老鼠有所不同。如果不能充分看到老鼠,一些技术人员会部分打开笼子,而另一些则使用LED手电筒。这些行为无疑会改变笼子的微环境,尤其是噪音、振动和光线,这些已知会影响小鼠的多种福利和研究相关参数。本研究的主要目的是评估在日常健康检查期间部分拆笼和使用LED手电筒对C57BL/6J小鼠的繁殖力、筑巢分数和毛发皮质酮浓度的影响,以确定进行这些健康检查的干扰最小的方法。此外,我们使用一个加速度计、一个麦克风和一个测光计来测量每个条件下的室内噪音、振动和光线。繁殖对(n = 100对)随机分为3个健康检查组:部分脱舱组、LED手电筒组和对照组(在不操纵笼子的情况下观察小鼠)。我们假设,在日常健康检查中暴露在手电筒或打开笼子的老鼠会比对照组的老鼠有更少的幼崽,更差的筑巢分数和更高的毛皮质酮水平。我们发现实验组与对照组相比,在繁殖力、筑巢得分或毛发皮质酮水平上没有统计学上的显著差异。然而,毛发皮质酮水平受到架子上笼子高度和研究时间的显著影响。这些结果表明,在C57BL/6J小鼠的巢得分和毛发皮质酮水平测量中,在日常健康检查期间,短时间、每天一次暴露于部分打开笼子或LED手电筒下,不会影响繁殖性能或健康。

期刊介绍: The Journal of the American Association for Laboratory Animal Science (JAALAS) serves as an official communication vehicle for the American Association for Laboratory Animal Science (AALAS). The journal includes a section of refereed articles and a section of AALAS association news. All signed articles, including refereed articles and book reviews, editorials, committee reports, and news and commentary, reflect the individual views of the authors and are not official views of AALAS. The mission of the refereed section of the journal is to disseminate high-quality, peer-reviewed information on animal biology, technology, facility operations, management, and compliance as relevant to the AALAS membership. JAALAS accepts research reports (data-based) or scholarly reports (literature-based), with the caveat that all articles, including solicited manuscripts, must include appropriate references and must undergo peer review.
