圈养环境如何影响动物的行为，关系到圈养动物的福祉。圈养在许多方面与自然环境背道而驰，而丰富实践的一个目标是鼓励在这些非自然环境中的物种典型行为。这项研究调查了在加州国家灵长类动物研究中心的室外围栏中饲养的七组圈养恒河猴，草和砾石基质对活动预算和脱毛程度的影响。与砾石基质组相比，草基质组花了更多的时间寻找食物，而花了更少的时间梳理。在砾石围栏中花费更多的时间梳理可能是导致这些围栏中明显更大的脱发的原因。在研究中途从砾石基质转移到草基质的一组中，活动预算和脱发的类似变化加强了地面基质对觅食和梳理以及因此脱发之间的因果关系。这些结果增加了越来越多的证据表明，圈养的底物类型是重要的考虑因素，因为它影响动物的健康。特别是，这些结果表明，草基质比砾石基质更有效地刺激觅食，将异质梳理减少到与野生种群相当的水平，并使动物保持更健康的皮毛。上午好。J.Primatol。2008年，70：1160-1168。(C)2008年Wiley-Liss，Inc.
How the captive environment influences the behavior of animals is relevant to the well-being of captive animals. Captivity diverges from the natural environment in many ways, and one goal of enrichment practices is to encourage species-typical behavior in these unnatural environments. This study investigated the influence of grass vs. gravel substrate on activity budgets and degree of hair loss in seven groups of captive rhesus macaques housed in outdoor enclosures at the California National Primate Research Center. Groups having grass substrate spent a greater proportion of their time foraging and a smaller proportion of time grooming compared with groups having gravel substrate. Increased time spent grooming in gravel enclosures may have contributed to significantly greater hair loss in those enclosures. A causal relationship between ground substrate on foraging and grooming, and therefore hair loss, is strengthened by similar changes in activity budgets and hair loss in a single group that was moved from gravel to grass substrate halfway through the study. These results add to growing evidence that substrate type in captivity is important to consider because it affects animal well-being. In particular, these results reveal that grass substrate is more effective than gravel in stimulating foraging and reducing allo-grooming to levels that are comparable to wild populations, and enable animals to maintain healthier coats.
