Three photoperiods were applied: a short photoperiod (8L∶16D), normal photoperiod(12L∶12D) and a long photoperiod(16L∶8D). The results show that digestibility and assimilation rate were highest in the short photoperiod with values of 83 97%±1 16% and 80 46%±1 34%, and lowest in the normal photoperiod with values of 81 74%±1 76% and 78 45%±1 41%. Moreover, the energy intake, digestibility and assimilated energy of N. confucianus decreased with the amount of daylight. The statistical significance of the results obtained by a one-factor analysis of variance were all less than 0 01 or 0 05 except for digested energy. This indicates that photoperiod is an important environmental factor to affect the energy metabolism of Niviventer confucianus .展开更多
