While the benefits of pair housing have been well documented, less is known about increasing success in adult male macaque pair introductions. In this retrospective study, 95 unfamiliar adult male macaque () pairs were examined to determine whether duration of visual contact, behavior, and age and weight were associated with success rate, with "success" defined as two weeks in full tactile contact without excessive behavioral indicators of incompatibility or injury requiring clinical treatment or care. Overall, the unfamiliar adult male pairs achieved a success rate of 72% and wounding requiring medical attention was rare (2%). A significant negative relationship between pair success and time in visual contact for pairs was found. Pairs who moved into tactile contact within 48-hours showed more positive social behaviors in protected and full contact and had a high rate of success (91%), while those who exhibited negative social behaviors were maintained in visual contact for longer. Nevertheless, rapid signs of compatibility were not necessary for the formation of successful pairs. While social introduction success rates steadily declined with increased periods of maintained visual contact, longer durations of 3 days to 1 week (70%), and 8+ days (58%), were still accompanied by high to moderate success, respectively. These results indicate that when negative social behavior is present early in visual contact success may be expected to decrease, but it is not necessarily indicative of incompatibility. Providing extra time in visual contact can reduce overall incidences of single housing.
虽然成对饲养的益处已有充分记录,但对于提高成年雄性猕猴配对引入的成功率却知之甚少。在这项回顾性研究中,对95对不熟悉的成年雄性猕猴进行了检查,以确定视觉接触时长、行为以及年龄和体重是否与成功率相关,“成功”定义为在完全触觉接触两周内,没有出现不相容或受伤的过度行为指标,且无需临床治疗或护理。总体而言,不熟悉的成年雄性猕猴对的成功率为72%,需要医疗护理的受伤情况很少见(2%)。研究发现,配对成功率与视觉接触时间之间存在显著的负相关关系。在48小时内进入触觉接触的配对在受保护的完全接触中表现出更积极的社交行为,且成功率很高(91%),而那些表现出负面社交行为的配对则在视觉接触中维持的时间更长。然而,成功配对的形成并不一定需要快速出现相容的迹象。虽然随着视觉接触维持时间的增加,社交引入成功率稳步下降,但3天至1周(70%)和8天以上(58%)的较长时间仍分别伴随着较高到中等的成功率。这些结果表明,当在视觉接触早期出现负面社交行为时,成功率可能会下降,但这不一定表明不相容。提供额外的视觉接触时间可以减少单独饲养的总体发生率。
