Abstract: Energy metabolism and behavior of musk deer during pregnancy and lactation wasstudied．The results showed：Average dry matter intake of prenancy female was 31·39± 8．31g／Kg^0.75 Per day，43．12% more than unfertilized female；Average total energyintake of pregnancy female was 556．51± 146．79KJ／Kg^0.75Perday，50．8% more thanunfertilze one． During the lactation period．average dry matter intake was 69．22± 10．09g／Kg ^0.75 for female with twins and 57．56± 9．08g／Kg^0.75 for female with single baby．Average total energy intake of lactation female(twins)was 1265．65 ± 181．92 KJ／Kg^0.75and 1052．73± 1 64．83KJ／Kg^0.75 for single baby a female，about 2. 27 (twins)and1．89 (single baby)time greater than pregnant female． According to the observation ofbehavior，musk deer spent more time on resting (1ying，sitting), in order to save theenegryduring reproductive period．
They also spent m ore tim e on feeding，especially in the lactation period．These results provide database for making ration of breeding in reproductive period．

摘要： 本文对饲养条件下林麝妊娠期和哺乳期的能量需要和行为特征进行了研究结果表明，妊娠初期和妊娠后期能量摄取量分别比孕前增加丁48．9% 和95．6% 哺乳期总摄入能比妊娠期分别高2．27倍(双胎)和1．89倍(单胎)。根据在繁殖期对麝的行为观察，我们推断：麝是通过增加采食时间来增加能量的摄取，并通过减少活动，增加躺卧时间来减少能量梢耗，以此满足繁殖期的能量需要。这些将结果为制定麝繁殖期的饲养标准和管理措施提供了依据。
