Adult female rats showed increase in ambulatory activity and marked decrease in drinking behavior at early dark period (18:00-24:00) of proestrus stage before ovulation. In this study, we observed the changes in patterns of ambulatory and drinking activities of immature rats associated with estrous cycle during growing period. Immature female rats of the Wistar-Imamichi strain were used, and both behavioral activities were measured continuously, using Gundai type Ambulodrinkometer. From these observations, it was found that the typical patterns of ambulatory and drinking activities which were observed in adult female rats appeared at the sixth (51-60 days old) and the third (39-49 days old) estrous cycle, respectively.
成年雌性大鼠在排卵前动情前期的早期黑暗期（18:00 - 24:00）出现活动增加和饮水行为显著减少。在本研究中，我们观察了未成年大鼠在生长期与发情周期相关的活动和饮水活动模式的变化。使用了Wistar-Imamichi品系的未成年雌性大鼠，并使用群带式活动饮水测量仪连续测量两种行为活动。从这些观察结果发现，成年雌性大鼠中观察到的典型活动和饮水活动模式分别出现在第六个（51 - 60日龄）和第三个（39 - 49日龄）发情周期。
