Modern zoos strive to improve standards of animal management, husbandry and welfare of their animals as part of a continual evaluation process. Elephants (Elephantidae) have received particular attention in recent years due to the challenge of providing environments which promote natural behavior and opportunities for social interaction. A number of measures have been proposed to measure wellbeing, with sleep quality increasingly being used. Sleep is a vital aspect of life for cell replenishment as well as optimal development of young. Sleep deprivation can lead to immunosuppression and illness; therefore animal managers have a responsibility to ensure they reduce the potential for disturbance through noise, light, or other environmental factors. The social environment also plays an essential role in wellbeing, particularly for species that live in multi-generational family units. In this study the nocturnal behavior of a multi-generational captive herd was observed to determine impacts of husbandry changes on sleep duration and bout length (measured as recumbent rest). As expected, average total duration of sleep was higher in younger elephants and rates were comparable to those reported in other studies of Asian elephants. Overnight access to an outdoor paddock in warmer weather increased overall average bout length of sleep in the herd. Average total duration of sleep also increased for the herd following the movement of an unrelated adult female who had previously shown weak bonds with other herd members. This indicates that social compatibility is a vital component of elephant welfare, impacting not only behavioral interactions but sleep quality and duration.

社会和环境对圈养亚洲象睡眠的影响（大象）

作为持续评估过程的一部分，现代动物园努力提高动物管理、饲养和动物福利的标准。由于提供促进自然行为和社会互动机会的环境的挑战，大象（象科）近年来受到了特别关注。已经提出了许多衡量幸福感的措施，越来越多地使用睡眠质量。睡眠是生命的重要方面，可以补充细胞以及年轻人的最佳发育。睡眠不足会导致免疫抑制和疾病；因此，动物管理者有责任确保他们减少因噪音、光线或其他环境因素造成干扰的可能性。社会环境对幸福感也起着至关重要的作用，特别是对于生活在多代家庭单位中的物种。在这项研究中，观察了多代圈养牛群的夜间行为，以确定饲养变化对睡眠持续时间和回合长度（以卧位休息衡量）的影响。正如预期的那样，年轻大象的平均总睡眠时间更长，而且比率与其他亚洲象研究报告的睡眠时间相当。在温暖的天气里过夜进入户外围场增加了牛群的整体平均睡眠时间。在一个无关的成年女性移动之后，该群体的平均总睡眠时间也增加了，该女性之前与其他群体成员表现出较弱的联系。这表明社会兼容性是大象福利的重要组成部分，
