摘要
20 0 2年 1 1月～ 2 0 0 3年 1月 ,采用随机和焦点动物法对长颈鹿的日活动格局做了观察。结果表明 :摄食是越冬的主要行为 ,相对集中在昼间呈锯齿状多高峰均匀的采食节律 ,其次是反刍和卧息 ,最少是站立 ;孕鹿趋向于站立反刍并减少移动时间 ;雄鹿以最少的摄食时间获得最大的干物质净收益 。
From November 2002 to January 2003, the time budget of captive Giraffe in winter was observed using Focal Animal Sampling. The result showed that foraging behavior account for most for daily time, with a polyphasic and evenly distributed pattern during the daytime, followed by for ruminating and bedding.Least time was spent for standing behavior. The pregnant Giraffe spent more time in ruminating by standing and less time in moving around. The male tended to spend least time in foraging the most fodder. The Giraffe in captivity tended to budget daily time with a standing posture and nighttime with a resting posture of lying down.
