大熊猫饲养繁殖的研究与进展

国内外从１９３６－１９９２年，共在野外捕捉２６０支大熊猫，迄今尚活着的有７０支，死去的平均寿命低于野外２－３岁。自１９６３年北京动物园繁殖成功到１９９２年，共繁殖９４胎产１４１仔。迄今尚活着有３７支；死去１０４支。其中，仅活一周的有８４支，占死亡总数的８１％。双胞胎共４６胎，但全成活的仅３胎。说明亟待急需解决如何提高寿命和幼仔的存活率。

Development and progress of Breeding and Rearing Giant Pandas

4000 years ago it was likely that our country had begun to breed the giant panda, but modern zoo breeding giant panda took place in the Chicago Zoo, USA, 1936 and in the Beibei Park, Sichuan, China, 1939. From 1936 to 1992 all the zoo breeding giant pandas abroad and home from the wild are added up to about 260, till now only about 70 ones have survived. Those dead ones are aversgely one or two years younger than the wild ones. In 1963 the first example of artificial giant psnda reproduction was successfully achieved in the Beijing Zoo. During the long period from 1963 to 1992 there were 94 artificial birth and 141 cubs, 37 sarvived, 104 died. Those who only lasted their lives for only a week were 84, making up of 81% of the dead cubs. Of 94 birth there were 46 twins, but only three twins survived. It suggests that to raise the surviving rate of the cabs and last the adults' life attaches great importance to present giant pandas breeding and rearing.
