LD, long day; ns, non-significant; RQ, respiratory quotient; SD, short day. Values are presented as the mean ± SEM of ten animals per group. aEnergy balance was estimated by difference between energy intake and energy expenditure. bDenotes two-way ANOVA analysis: P, photoperiod effect; F, fruit effect; F*P, interaction effect of photoperiod and fruit treatment (P ≤ 0.05). *Effect of fruit on photoperiod group determined by Student’s t test (P ≤ 0.05).
