Japanese macaque societies are characterized by frequent intragroup conflict both in free-ranging and zoo-housed conditions. In zoos, understanding the factors that contribute to wounding is of interest because this knowledge can aid in proactive husbandry and management planning that can minimize the negative impacts wounding can have on individual welfare. This study sought to determine whether the variables sex, season and age predicted wounding rates. Data were collected for 24 months on 119 Japanese macaques living in 10 zoos, and we analyzed the contribution of variables using generalized linear mixed models. A total of 1,007 wounds were reported, and the best model included the interaction between sex and season. Follow-up analyses revealed that females incurred more wounds than males, and this sex difference was more pronounced during the breeding compared to the nonbreeding season. On average, individuals received 4.67 (±SEM: 0.55) wounds per year and 77.31% of the population incurred at least one wound in the study period. The majority of wounds were superficial and did not require veterinary intervention. Wound locations were not randomly distributed across body regions and were most often reported on the face. Finally, macaques living in larger social groups experienced more wounds, on average. This study represents the first quantification of wounding in this species and may provide insight to help inform husbandry and management strategies in zoos.

性别和季节预测动物园饲养的日本猕猴 (Macaca fuscata) 的伤口:一项多机构研究

日本猕猴社会的特点是在自由放养和动物园条件下频繁发生群内冲突。在动物园中,了解导致受伤的因素很重要,因为这些知识可以帮助制定积极的饲养和管理计划,从而最大限度地减少受伤对个人福利的负面影响。这项研究试图确定变量性别、季节和年龄是否能预测受伤率。收集了生活在 10 个动物园中的 119 只日本猕猴 24 个月的数据,我们使用广义线性混合模型分析了变量的贡献。总共报告了 1,007 处伤口,最佳模型包括性别和季节之间的相互作用。后续分析显示,女性比男性受伤更多,与非繁殖季节相比,这种性别差异在繁殖期间更为明显。平均而言,个体每年受到 4.67 (±SEM: 0.55) 处伤口,并且 77.31% 的人口在研究期间至少受到一处伤口。大多数伤口是浅表的,不需要兽医干预。伤口位置不是随机分布在身体各部位,最常报告在脸上。最后,平均而言,生活在较大社会群体中的猕猴遭受的伤口更多。这项研究代表了该物种受伤的首次量化,并可能提供洞察力,以帮助为动物园的饲养和管理策略提供信息。在研究期间,31% 的人口至少遭受了一处伤口。大多数伤口是浅表的,不需要兽医干预。伤口位置不是随机分布在身体各部位,最常报告在脸上。最后,平均而言,生活在较大社会群体中的猕猴遭受的伤口更多。这项研究代表了该物种受伤的首次量化,并可能提供洞察力,以帮助为动物园的饲养和管理策略提供信息。在研究期间,31% 的人口至少遭受了一处伤口。大多数伤口是浅表的,不需要兽医干预。伤口位置不是随机分布在身体各部位,最常报告在脸上。最后,平均而言,生活在较大社会群体中的猕猴遭受的伤口更多。这项研究代表了该物种受伤的首次量化,并可能提供洞察力,以帮助为动物园的饲养和管理策略提供信息。
