抱崽与否对笼养雌性食蟹猴个体社会行为的影响

目的比较笼养雌性食蟹猴抱崽与否,是否对其社会行为有影响。方法从2010年5月开始,在江苏省苏州中科实验动物有限公司猴场可观察的个体中,随机抽取观察对象40个;同年10月开始正式拍摄,样本中,11个个体抱崽,29个个体未抱崽。三名观察员采用焦点观察法,使用高清摄像机,对所有个体每天跟踪拍摄7个时间片段,每个时间段为30分组,每个个体观察4 d,共计完成有效累积观察时间560 h;将每天所拍摄视频汇总而后随机分配给NOLDUS分析员分析转换成为行为数据。结果抱崽个体多数时间是怀抱住幼崽,社会友好行为较多,比如为其他个体理毛或被其他个体理毛;社会地位较高,如与猴王共坐于制高点(悬于空中的板子或链子上,依据各个猴场饲养条件而议)时间较长;通讯行为较多,即努嘴行为;运动行为和交配行为较多;而未抱崽个体聚温行为较多,即与其他个体相互怀抱聚温;两组在摄食行为、发情行为、休息行为、冲突行为、警戒行为和各种自我行为差异无显著性。结论抱崽对雌性食蟹猴的社会行为有影响。

Influence of reared baby or not on the social behavior of female Macaca fascicularis in free enclosure

Objective To explore whether reared baby or not influences the social behavior of female Macaca fascicularis raised in free enclosure.Methods From May 2010,we randomly selected 40 monkey samples of the observation-available subjects from the rear base of Jiangsu Province Suzhou Zhongke Experimental Animals Co.Ltd.The formal observation was conducted from Oct 2010.Of the 40 female monkeys,11 subjects reared baby and 29 subjects did not.Focal observation method using high resolution digital camera was employed by three trained observers to record the behavior of target subjects,7 phases per day,30 min per phase,and each subject was observed for 4 days,with a totally effective observation time 560 hours.The recorded video clips were randomly delivered to the Noldus analysis system with an analysis reliability kappa 〉0.8,and transferred into behavior data.Results The subjects,who adopted baby,just hold the baby in most of time,more social amicable behavior,for instance,mutual grooming for others or being groomed by other companion,higher social rank,namely to share the rest place with monkey king on the board（which was hung across over the room） for longer time;more communication behavior,lip smacking;and more locomotive behavior and mating behavior with male subjects than those female monkeys not reared baby.Notwithstanding,the subjects who did not rear baby spent more time on embrace behavior with other companions.Otherwise,there were not significant differences on ingestive,rutting,rest,conflict,vigilance and miscellaneous behaviors.Conclusion The reared baby has influence on the social behavior of female Macaca fascicularis.
