摘要
1999～2006年北京南海子麋鹿苑出生麋鹿幼仔224只,新生麋鹿幼仔存活率81.70%,死亡率18.30%。41只麋鹿幼仔死亡的主要原因为死胎、弱胎和弃子等。分析仔鹿初生体重与仔鹿死亡关系发现,存活仔鹿与死亡仔鹿的初生体重具有极显著性差异,体重大的幼仔更容易存活,事实上初生体重小于6.00kg时仔鹿基本不能存活。北京南海子散放麋鹿难产率为2.23%(5/224),低于以往的记录。
The paper discussed the factors that affected the survival of the infants of milu（Elaphurus davidianus）,and hope to improve the infants＇ livability and provide experience of feeding and management for other zoos and breeding places.The objects of study are 224 infants of milu born during 1999 to 2006 in Nan Haizi Milu park in Beijing,and the death cause of 41 babies was also analyzed.The survive rate of infants was 81.70%,and the main reasons of the death were stillborn,weak-born,and abandoned,etc.There was significant difference（P=0.0000.001） between the birth weight and the infants＇ death,which means the heavier infants could survive easily.In fact,if the birth weight of the infant is less than 6.00 kg,it can＇t survive.The dystocia rate of milu deer living in Nan Haizi is 2.23%（5/224）,and the result is lower than record of past.
