摘要
2006年5-8月,采用行为取样法对济南动物园1只雌性圈养东北虎育幼期的行为进行了观察,旨在了解东北虎育幼期各种主要行为的活动节律和母性强弱的变化。结果显示：东北虎育幼期的主要行为包括休息、哺乳和运动3类,所占时间百分率分别为38%-51%、10%-39%、12%-25%,其他行为较少,仅占4%-15%。休息时间在1 d中几乎不间断;运动发生较少,主要集中在9：00-11：00和16：00-16：30;由于哺乳与休息具有同步性,哺乳发生次数也较多,没有明显的高峰期,一般每隔30 min就发生1次,1-1.5 h次/。在整个育幼期,母性行为哺乳所占时间比例呈下降趋势;亲仔时间变化不大;离开时间呈上升趋势,说明东北虎在育幼期内母性呈下降趋势。
