Fig. 3. Changes in the ‘general activity’ behaviour of mice fed the low-energy diet (A) from early pregnancy (N=15) and (B) from parturition (N=13). Observations made at night are identified by filled symbols; observations during the day are shown by open symbols. During both times of day, in both groups, the behaviour declined between early pregnancy and late lactation. Each point represents the mean percentage time spent in the behaviour across all mice. Parturition is day 0.
