Rhinoceros Conceived Artificially Born at California Zoo

人工受孕的犀牛在加利福尼亚动物园出生

A U.S.-based group is reporting the first successful artificial insemination birth of a southern white rhinoceros in North America.

一个总部设在美国的研究组织发表报告称,北美第一例成功进行人工授精的白犀牛产下了一头南方白犀牛。

The announcement came from San Diego Zoo Global, in San Diego, California. It describes the birth as an important step in saving another white rhino species from extinction.

这一消息来自加州圣地亚哥《圣地亚哥动物园全球报》。报告称,这是拯救另一品种白犀牛免于灭绝的重要一步。

San Diego Zoo Global said that mother Victoria gave birth Sunday to a healthy southern white rhino male at the San Diego Zoo Safari Park.

《圣地亚哥动物园全球报》称,上周日,一只名叫维多利亚的母犀牛在圣地亚哥野生动物园产下了一头健康的南部白犀牛。

“All of us at San Diego Zoo Global are (happy) with the arrival of this special rhino calf,” said Barbara Durrant. She works as the zoo’s director of reproductive science.

“这头特殊的小犀牛来到圣地亚哥动物园时,我们所有人都非常高兴,”芭芭拉·杜兰特说道。她是动物园生产科主任。

Doctors use artificial insemination methods to treat infertility in people and other creatures.

医生使用人工授精的方法来治疗人类和动物的不孕症。

San Diego Zoo Global reports that scientists gave Victoria a hormone, which caused her reproductive system to release an egg. Next, scientists injected semen from a male southern white rhino named Maoto. His reproductive fluid was collected and frozen before he died.

据《圣地亚哥动物园全球报》报道,科学家给维多利亚注射了一种激素,使她的生殖系统释放一个卵子。接下来,科学家们向这颗卵子中注射了一头名叫毛托的雄性南方白犀牛的精液。他的精液在他死前被收集并冷冻。

Victoria’s pregnancy was confirmed in March of 2018. She carried her baby for over a year — 493 days. Mother and baby will be kept away from the public to give them time to form a relationship.

维多利亚于2018年3月被确认怀孕。她怀胎一年多,共493天。母犀牛和小犀牛将远离公众,留给他们一些时间来形成亲密关系。

The calf will eventually meet the other five female rhinos at the Nikita Kahn Rhino Rescue Center. One of the five is named Amani. Scientists expect her to give birth in September or October.

这头小犀牛最终将在尼基塔·卡恩犀牛救援中心与其他五头母犀牛会合。五头犀牛中有一只叫阿曼尼。科学家预计它将在9月或10月分娩。

The new baby rhino “represents a critical step in our effort to save the northern white rhino from…extinction,” Durrant said.

杜兰特说,新出生的小犀牛“代表了我们在拯救北方白犀牛免于灭绝的努力中迈出的关键一步”。

Only two northern white rhinos currently remain on Earth. Both are female. The last male northern white rhino, named Sudan, died in March 2018.

目前地球上只剩下两头北方白犀牛。都是雌性。最后一只雄性北方白犀牛苏丹于2018年3月死亡。

Scientists collected sperm from Sudan and other males before they died. Now, those scientists hope to use that sperm to help bring back the species.

科学家在苏丹和其他雄性白犀牛死亡前收集了他们的精子。现在,这些科学家希望用这些精子来帮助恢复物种。

Southern white rhinos are a sub-species, or smaller grouping, of northern white rhinos. Scientists say the southern white rhino female will soon be used to carry northern white rhino embryos. Using these processes, researchers believe that a northern white rhino baby could be born within 10 to 20 years.

南方白犀牛是北方白犀牛种群中的一个亚物种,或更小的群体。科学家说,南部白犀牛的雌性不久将开始被植入北部白犀牛的胚胎。利用这些过程,研究人员相信,北方白犀牛宝宝可能会在10到20年内出生。

Rhinos have long been hunted, and several sub-species are at risk of disappearing forever. The International Union for Conservation of Nature has put the southern white rhino on its Red List of Threatened Species.

犀牛一直在被猎杀,有几个亚种也在面临着永远消失的危险。国际自然保护联盟已将南方白犀牛列入濒危物种红色名单。
