实验室猕猴的成对住房被广泛认为会导致幸福感的积极变化，但引入的过程被认为是潜在的压力和风险。行为和生理数据收集8个成年雄性恒河猴的过程中，引进之前，期间和之后，为了测量引进的初始压力，以及长期的福祉变化。在五个连续阶段对所有植入生物遥测装置的有社会经验的受试者进行研究：基线（单独圈养）、受保护接触和完全接触引入各1天、引入后（引入后1-3周）和固定配对（引入后>= 20周）。分析了176小时的行为数据和672小时的心率数据。还测量了基线、引入后和固定配对阶段的粪便皮质醇。所有的介绍都是成功的，受试者没有表现出压力的生理或行为迹象，如心率增加，异常行为或痛苦的心理指数（抑郁/焦虑相关行为）。在整个导入过程和随后的几个月内，激动作用极轻微;在研究过程中仅发生1例伤口。异常行为的水平，心理指标的困扰，运动，不活动，和联系显示在几个星期内引入后的改善;这些变化仍然存在5-9个月后的后两个类别。心率在引进过程中显着下降，在解决对阶段，也随着时间的变化。粪便皮质醇水平较低，在解决对比在单一住房。事实上，异常行为的减少并没有长期持续下去，这可能是由于笼中时间的增加而混淆的。本研究的结果可能是实际使用的设计和监测社会介绍，并建议管理人员不应忽视的可行性，成功配对的成年雄性恒河猴。
Pair housing of laboratory macaques is widely considered to lead to positive changes in well-being, yet the process of introduction is viewed as potentially stressful and risk-prone. Behavioral and physiological data were collected on eight adult male rhesus macaques before, during, and after the process of introduction, in order to measure the initial stress of introduction as well as long-term changes in well-being. Socially experienced subjects, all implanted with biotelemetry devices, were studied in five successive phases: baseline (singly housed), I day each of protected contact and full contact introduction, post-introduction (1-3 weeks after introduction), and settled pairs (>= 20 weeks after introduction). One hundred and seventy-six hours of behavioral data and 672 hr of heart rate data were analyzed. Fecal cortisol was also measured for the baseline, post-introduction, and settled pair phases. All introductions were successful and subjects showed no physiological or behavioral signs of stress, such as increased heart rate, abnormal behavior, or psychological indices of distress (depressive/anxiety-related behavior). Agonism was minimal throughout the introduction process and over the subsequent months; only one wound was incurred over the course of the study. Levels of abnormal behaviors, psychological indices of distress, locomotion, inactivity, and affiliation showed improvements within several weeks after introduction; these changes were still present 5-9 months later for the latter two categories. Heart rates during introduction fell significantly in the settled pair phase, and also varied predictably with time of day. Fecal cortisol levels were lower in settled pairs than in single housing. The fact that reductions in abnormal behavior did not persist over the long term may have been confounded by increasing duration of time spent caged. The results of this study may be of practical use for designing and monitoring social introductions and suggest that managers should not dismiss the feasibility of successful pairing of adult male rhesus macaques.
