BACKGROUND
Compatible pair housing of macaques in research settings increases species-typical behaviors and facilitates beneficial social buffering. It is not yet established whether these benefits are maintained after intrafacility transfer and domestic quarantine, which are two stressors that can lead to behavioral and clinical abnormalities.
METHODS
We evaluated 40 adolescent male rhesus macaques who were single- or pair-housed immediately following an intrafacility transfer. We measured behavior, fecal cortisol, body weight, and diarrhea occurrence. Body weight and diarrhea occurrence were also retrospectively analyzed in an additional 120 adolescent rhesus who underwent a similar transfer.
RESULTS AND CONCLUSIONS
Pair-housed macaques exhibited less of some undesirable behaviors (e.g., self-clasping) and experienced less diarrhea than single-housed subjects; however, no significant differences in cortisol levels or alopecia measures were found. The demonstrated beneficial effects of pair housing for rhesus macaques following intrafacility transfer and adjustment suggest pairing upon arrival at a new facility will bolster animal welfare.
背景
在研究环境中，将猕猴进行配对饲养可以增加其物种典型行为，并促进有益的社会缓冲。然而，目前尚不清楚这些益处是否能在设施内转移和国内检疫后维持，因为这两个压力源可能导致行为和临床异常。
方法
我们评估了 40 只处于青春期的雄性恒河猴，这些猴子在设施内转移后立即进行单只或成对饲养。我们测量了行为、粪便皮质醇、体重和腹泻发生情况。还对另外 120 只经历过类似转移的青春期恒河猴进行了体重和腹泻发生情况的回顾性分析。
结果与结论
与单只饲养的猴子相比，成对饲养的猴子表现出较少的一些不良行为（例如，自我扣紧），并且腹泻较少；然而，皮质醇水平或脱发测量值没有发现显著差异。设施内转移和调整后，恒河猴配对饲养的有益效果表明，在新设施到达时进行配对将增强动物福利。
