Rhinoceros Conceived Artificially Born at California Zoo

通过人工受孕降临的白犀牛在加利福尼亚州动物园出生

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

一个美国的组织报道称首个通过人工授精产生的南方白犀牛在美国北部成功出生。

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.

此宣告出自于加利福尼亚州圣地亚哥的圣地亚哥动物园全球。它将这次出生描述为拯救另外一种白犀牛物种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表示犀牛妈妈维多利亚于周日在圣地亚哥野生动物园产下一头健康的雄性南方白犀牛。

“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.

“在圣地亚哥全球的所有人都对这头特殊的犀牛幼崽的降临感到很开心,”芭芭拉·杜兰特表示。她在这个动物园担任生殖科学主任。

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

医生使用人工授精的方式治愈人类和其他物种的不育症。

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.

圣地亚哥动物园全球报告称科学家们给维多利亚注射了荷尔蒙。荷尔蒙可致使她的生殖系统释放一颗卵子。接着科学家将从一只名为Maoto的雄性南方白犀牛那里获得的精子注射入她体内。他的生殖液体是在他死之前收集并储存起来的。

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.

在2018年三月确认了维多利亚已经怀孕。她孕育了她的胎儿一年多的时间也就是493天。妈妈和幼崽将被与牛群隔离以给它们时间去培养感情。

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.

这只小牛终将与其他五头母犀牛在尼基塔卡恩犀牛救助中心接触。这五头犀牛中有一只叫做阿曼尼。科学家希望她能在九月或者十月生产。

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

这只新生的幼崽“代表着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,”杜兰特说。

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

现今地球上只生存了两头北方白犀牛。它们都是母犀牛。名为Sudan的最后一头雄性北方白犀牛死于2018年3月。

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.

在Sudan和其他雄性犀牛死亡之前科学家从它们体内收集了精子。现在这些科学家希望利用那些精子去帮助恢复物种。

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的亚种或者更小的种群。科学家表示雌性南方白犀牛不久将被用来孕育北方白犀牛的胚胎。使用这些过程,研究人员认为一只北方白犀牛幼崽可在10到20年内被产下。

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.

犀牛很久之前就被猎杀了以及几种亚种也在面临着永久消失的危机。世界自然保护联盟已经将南方白犀牛列入濒危物种红色名录。

Rhinoceros Conceived Artificially Born at California Zoo
