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．
