RISK FACTORS FOR SELF INJURIOUS BEHAVIOR IN CAPTIVE RHESUS MONKEYS

研究表明，大约10%的圈养动物，单独 家养的猴子在兽医方面有过一些自我伤害的记录 在他们的一生中的行为(SIB)。考虑到这种特殊的和 SIB的异质性，似乎不太可能是单一的原因 将会被发现。这次调查的目的是确定 SIB的可能危险因素通过检查人口统计学， SIB的环境、发育和行为相关因素。 188只黑猩猩群体记录和行为评估的检验 NERPRC的雄性单独饲养的恒河猴(14%被评估为 表现出自咬行为)产生了3个潜在的危险因素。 首先，SIB猴子在单独的笼子里呆的时间比对照组多 (6.4年对4.2年)。其次，SIB猴子是 单独居住的年龄比对照组年轻(16.2个月比 28.5个月)；这表明个人更容易受到伤害 为年幼的动物提供住所。第三，SIB猴子被转移到 同一房间内的不同笼子比对照组更常见(3.5 移动与1.7移动)。而个人住房可能是因果关系 与SIB的发展有关，目前尚不清楚 动物被关进不同的笼子是SIB的原因或结果。 然而，这些结果支持这样的观点，即某些养育和 住房条件以及对日常生活的过度干扰 可能会导致或加剧猕猴的自我伤害行为。

Research has shown that approximately 10% of captive, individually housed monkeys have had some veterinary record of self-injurious behavior (SIB) within their lifetime. Given the idiosyncratic and heterogeneous nature of SIB, its seems unlikely that a single cause will be discovered. The purpose of this investigation was to identify possible risk factors for SIB by examining the demographic, environmental, developmental, and behavioral correlates of SIB. Examination of the colony records and behavioral assessments of 188 male individually housed rhesus monkeys at the NERPRC (14% assessed as showing self-biting behavior) yielded 3 potential risk factors. First, SIB monkeys spent more time in individual cages than controls (6.4 years versus 4.2 years). Second, SIB monkeys were individually-housed at a younger age than controls (16.2 months versus 28.5 months); suggesting an increased vulnerability to individual housing for younger animals. And third, SIB monkeys were moved into different cages within the same room more often than controls (3.5 moves versus 1.7 moves). Whereas individual housing may be causally linked to the development of SIB, it is unclear whether movement of animals to different cages was a cause or a consequence of SIB. Nevertheless, these results support the ideas that certain rearing and housing conditions as well as excessive disruption of daily routines may either cause or exacerbate self-injurious behavior in macaques.
