The feeding microstructure of male and female mice
Fig 2
Daily energy intake and ambulatory activity of normal mice housed in groups.
A. Daily energy intake of 10w, 20w and 30w old males and females. Intake was continuously computed during 14 days in mice fed ad libitum of a chow diet (3.0 kCal/g). Results are expressed as the mean ± SEM after adjusting to the mean BW recorded during the same period of time (n = 10, *p<0.05 sex; ●p<0.05 vs. 10w old mice, F(14,183) = 1.79, p<0.05). B. Mean adjusted nocturnal and diurnal energy intake of group-housed mice at 10w, 20w and 30w of age (n = 10, *p<0.05 sex, F(14,183) = 1.79, p<0.05). C. Circadian variation and cosinor analysis of adjusted energy intake in males and females of the indicated ages continuously computed in bins of 60min during 14 days of ad libitum feeding. Data for cosinor analysis is shown in Table 1. D. Circadian variation and cosinor analysis of net random ambulatory activity of mice of the indicated sexes and ages. Data represents the mean ± SEM of daily activity recorded throughout the course of 14 days of ad libitum feeding.
