摘要
食物资源或能量收支的变化会影响动物的行为模式。该研究采用高纤维饲料和标准鼠饲料分别饲喂两组板齿鼠,以红外摄像机录像第20天时各组板齿鼠取食、活动、休息和理毛等4种行为,分析了板齿鼠的昼夜节律及高纤维食物对其昼夜节律的影响。结果表明,板齿鼠的活动行为主要在夜间进行;高纤维食物对板齿鼠行为模式的影响主要表现在夜间活动、取食增多,而白天休息增多。
Food resources and energy budget affect the behaviors and time budgets of animals.To clarify the effects of a high-fiber diet on greater bandicoot rat （Bandicota indica） behavior,we compared B.indica under a high-fiber diet and a standard rat diet using video monitoring.Our results show that B.indica are mainly active and feed at night,typical of nocturnal animals.A high-fiber diet resulted in a longer time to feed and become active at night and reduced the time spent feeding during the day.These findings suggest that food quality plays an important role in the behavioral timing of B.indica;this helps to understand seasonal changes in behavior demonstrated by B.indica.
