Possible social distress was evaluated in 20 adult rhesus macaques housed in compatible isosexual pairs (5 female pairs, 5 male pairs) for the purpose of social environmental enrichment. Serum cortisol concentrations of paired animals were compared with serum cortisol concentrations of individually housed adult rhesus macaques of both sexes (5 females, 5 males). In both sexes, cortisol concentrations of paired animals (means 10 females = 19.5 +/- 2.9 micrograms/dl; means 10 males = 17.5 +/- 4.6 micrograms/dl) showed no significant difference (p always greater than 0.1) with those of single animals (means 5 females = 20.5 +/- 2.1 micrograms/dl; means 5 males = 15.9 +/- 2.6 micrograms/dl). Both in male and in female pairs, dominant partners had cortisol concentrations that were equivalent to those of their subordinate counterparts. It was concluded that neither female nor male adult rhesus macaques experience more distress when sharing a cage with a compatible partner of the same sex than when living alone.
为了丰富社会环境，对20只成年恒河猴进行了可能的社会应激评估，这些猴子以性别匹配的配对形式饲养（5对雌性，5对雄性）。将配对动物的血清皮质醇浓度与单独饲养的成年雌雄恒河猴（5只雌性，5只雄性）的血清皮质醇浓度进行比较。在两性中，配对动物的皮质醇浓度（10只雌性的平均值 = 19.5 +/- 2.9微克/分升；10只雄性的平均值 = 17.5 +/- 4.6微克/分升）与单独饲养动物的皮质醇浓度（5只雌性的平均值 = 20.5 +/- 2.1微克/分升；5只雄性的平均值 = 15.9 +/- 2.6微克/分升）相比，没有显著差异（p始终大于0.1）。在雄性和雌性配对中，占主导地位的伙伴的皮质醇浓度与它们的从属伙伴相当。得出的结论是，成年雌性和雄性恒河猴与同性合适伙伴同笼饲养时，并不比单独生活时经历更多的应激。
