By agreement, all cubs born at the zoo are sent to China when they are 4 years old.
根据协议,所有在该动物园出生的熊猫幼崽都将在4岁时被送回中国。
如今,22岁的美香快要结束育龄。据《华盛顿邮报》报道,动物园于3月份用雄性大熊猫的冷冻精子对这只大熊猫进行了人工授精,此后一直在监控美香的情况。
Reproductive scientists from the Smithsonian Conservation Biology Institute and zoo veterinarians performed the artificial insemination of Mei Xiang in late March, with frozen semen collected from Tian Tian, Mei Xiang's companion who also came to the zoo nearly 20 years ago, the zoo said in a statement.
动物园在一份声明中说,来自史密森保护生物学研究所的生殖科学家和动物园兽医在3月下旬为美香进行了人工授精。使用的冷冻精子来自美香的同伴添添,添添在近20年前和美香一起来到动物园。
令人担忧的是,美香之前有两次怀过双胞胎,而每次都只有一个宝宝存活。如今她作为“高龄产妇”,即使怀孕,也面临着一定风险,牵动着工作人员的心。
The panda could also have a stillbirth, or the fetuses could be resorbed, said spokeswoman Pamela Baker-Masson.
发言人Pamela Baker-Masson说熊猫宝宝有可能死产,胚胎也可能被吸收。
Chief veterinarian Don Neiffer said the zoo’s panda pregnancy team would meet and make sure everyone was ready. “It takes a village to raise a panda — or at least get one out,” he said.
