环境丰容对赤猴行为分配影响的研究

Influence of environment enrichment to the behaviors of Erythrocebus patas in captive

2011年初福州动物园饲养的3公3雌赤猴出现行为单一、毛发粗糙、尾部干枯断裂、见有跛行等不良生长状况。为了改变猴群出现的不良状况,福州动物园将赤猴转移至新兽舍饲养,该新兽舍有较大的活动空间、良好的植被覆盖,还在新兽舍中安置有假山、攀网、跑道等设施供赤猴锻炼。此外,还将赤猴部分饲料由定点投喂改为抛洒投喂。经过约一年适应,赤猴昼间行为分配相较旧笼时觅食和运动行为分别提高61.3%、213.2%;行走和休息时间分别减少41.2%、26.7%,猴群被毛良好,尾部恢复正常,跛行现象基本消失。

In 2011, the 3 male and 3 female Erythrocebus patas raised in Fuzhou Zoo suffered from such unhealthy growing conditions as unitary behavior, coarse hairs, dry and ruptured tails and claudication, etc. They were transferred to a cage with certain environment enrichment and stayed for one year. Compared with the conditions in the previous cage, the allocations of Erythrocebus patas' daytime behaviors of foraging and sports increase by 61.3% and 213.2% respectively, and their walking and resting time decrease by41.2% and 26.7% respectively. Now, the Erythrocebus patas have fine hairs, their tails recover to normal conditions, and claudication basically disappears.
