摘要: 近年来,在动物园内人工饲养下的大熊猫(Ailuropoda melanoleuc),由于雌雄个体常常不能同时发情,甚至都不发情,因而不能正常产仔。故大熊猫的繁殖问题就成为国内外各动物园所关注的问题之一。 北京动物园大熊猫于1963年自然交配产仔首次成功。1978年以后,国内外动物园又相继进行了上百次的人工授精试验,据报道,真正受孕产仔的仅有中国的北京、上海、成都、杭州以及西班牙的马德里和墨西哥等动物园。可见其受精率很低。

Abstract: This paper deals with the oestrus behavior of two pandas in April, 1982 and in March-April, 1983.During their oestrus, the male shows expansion of testis and the female has scent-marking behavior, the most of the scent-marking of the female has come up to 247 times a day.One of the courtship behavior of female and male is bleating, the frequency of which is 257 at most in a day.The content of panda chorionic gonadotrophin(FCG)in serum and urine of the female after artificial insemination is determined. The content of PCG in serum is 5.9μg/ml in the 5th week, and 8.5μg/ml in the 10th week. The content of PCG in urine is 3.6μg/ml in the llth week, and 1-2 μg/ml in the 15th week, and the PCG disappeared entirely after 18th week. The content of PCG is determined on the first day of each week.The cutitular epithelial cells of the vaginal secretion during the oestrus are examined.Their body temperatures are higher in the period of oestrus than otherwi se.The normal range of body temperatures of pandas is 36.5-37.2℃ in non-oestrus. The body temperatures of the female range 38.2-38.8℃,the male 38,4-38.6℃ in the oestrus.
