海豚妊娠分娩哺育期间的观察及护理

OBSERVATIONS AND CARE OF A DOLPHIN DURING GESTATION,PARTURITION AND LACTATION

野生海豚的妊娠、分娩及哺育过程很难进行科学、系统地观察监测,人工饲养海豚的繁殖情况却屡见报道。我馆于2003年3月20日从日本购进 6 头雌性太平洋瓶鼻海豚(Tursi ops truncatus aduncus),其中1头编号为“270”的海豚于2003年6月19日顺利产下1头雄性幼仔,作者对其母子进行每天24h看护达2 周之久。此后的 1 年中,幼仔生长良好。本文就海豚“270”的妊娠、分娩及哺育过程进行详细描述,并将工作人员对“270”母子采取的护理措施作一具体说明。

The systematic and scientific observation of the gestation, parturition and lactation of dolphins in the wild is very difficult,but the reproductive process of captive dolphins has often been recorded. On March 20,2003 the Beijing Aquarium acquired six bottlenose dolphins from Japan. One individual, which was to be known as “270”,gave birth to a male calf on June 19,2003.The birth was successful. The mother and calf were observed day and night for two weeks. During its first year the calf grew well. This article describes the processes of 270's gestation, parturition and lactation in detail, and explains the physical husbandry and social management given by the trainers and veterinary staff.
