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。 Changes in food resources or energy revenues affect the behavior patterns of animals. In this study, two groups of raccoon dogs were fed with high-fiber diet and standard rat diet respectively. Four kinds of raccoon feeding, activity, rest and grooming were recorded on the 20th day after the infrared camera was recorded. The circadian rhythm and the effect of high fiber foods on its circadian rhythm. The results showed that the activities of plateau rats were mainly in the night. The effects of high-fiber diet on the behavioral patterns of plateau rats were mainly manifested as nocturnal activities, increased feeding and increased daytime rest.
