文摘内容
Digested energy, metabolizable energy, digestibility and assimilation rate were quantified at different photoperi-ods in Niviventer confucianus using the food balance method. 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 as-similation 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, di-gestibility 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。
