Abstract

Background

Previous studies suggest that housing relocation may be stressful for captive non-human primates. Our study investigated the stress levels of Japanese macaques during a housing relocation by measuring their daily fecal cortisol metabolites, which are often used as an indicator of stress.

Methods

Ten adult Japanese macaques, single-housed for research purposes, were relocated to a new facility. Fecal samples were collected daily for 7 days. Cortisol metabolite concentrations were determined via enzyme immunoassay.

Results

No significant differences in cortisol metabolite levels were found in 7 days, but concentration levels showed that the highest median was associated to the relocation day.

Conclusions

The minimal cortisol metabolite increase suggests that there was a slight activity increase in the hypothalamic-pituitary-adrenal axis. Techniques encouraging cooperation of the monkeys, the short time duration of the relocation, and consistency in the environment may have contributed to the minimal stress levels observed.

在圈养的日本猕猴(Macaca fuscata)中，住房搬迁并不一定会引起显著的应激反应。

背景:以往的研究表明，对圈养的非人灵长类动物来说，住房搬迁可能会带来压力。我们的研究通过测量日本猕猴每天的粪便皮质醇代谢物(通常被用作压力指标)来调查日本猕猴在住房搬迁期间的压力水平。方法:10只成年日本猕猴，为研究目的，被安置到一个新的设施。每天收集粪便样本，连续7 d。通过酶免疫分析法测定皮质醇代谢物浓度。结果:7天内皮质醇代谢物水平无显著差异，但浓度水平显示最高中位数与迁移日有关。结论:最小的皮质醇代谢物增加表明下丘脑-垂体-肾上腺轴有轻微的活动增加。鼓励猴子合作的技术、迁移的短时间和环境的一致性可能是观察到的最小压力水平的原因。
