MARBLE HALL, South Africa, Sept 23 (Reuters) - Almost 40 years after the first human 試験管ベビー was born, South African scientists have produced something bulkier: the first Cape buffalo brought into the world by in vitro fertilisation (IVF).
Pumelelo the buffalo bull calf was born on June 28 and was 明かすd to the world this week at a game farm north of Johannesburg in South Africa's Limpopo 州.
The technique 持つ／拘留するs hope for far bigger and more 危うくするd 種類 such as the northern white rhino - only three of them are left on the 惑星.
"This success is of major importance for the 見込みのある 産む／飼育するing of 危うくするd 種類, and that is the 推論する／理由 why we are 請け負うing this work," said Morne de la Rey, a veterinarian and the managing director of Embryo 加える, which specialises in bovine embryo 移転s and semen collection, mostly for the cattle 産業.
Proud parents are 生物学の mother and egg 寄贈者 "Vasti" and sperm 寄贈者 "Goliat", which is Afrikaans for Goliath - in his bulky 事例／患者, no misnomer. The baby bull has a surrogate mother which has taken to him.
He could grow to 1,000 kg (2,200 続けざまに猛撃するs) or more.
Cape buffalos are 悪名高くも bad-tempered and dangerous animals and Vasti was sedated when her oocytes, or egg 独房s, were 抽出するd using a technique 類似の t o that used on human 寄贈者s.
Game farming is big 商売／仕事 in South Africa but those 伴う／関わるd in the 事業／計画（する） said the main 関心 was 自然保護.
"The 反対する is certainly not to 再生する buffalo of superior genetics ... the goal is the 自然保護 of 種類," said Frans Stapelberg, the owner of the farm where Pumelelo was born.
The 事業／計画（する） will now 焦点（を合わせる） on the northern white rhino and the trio who remain on the 惑星 on the Ol Pejeta Conservancy in Kenya. The San Diego Zoo is partnering with that 成果／努力.
There are around 18,000 to 20,000 southern white rhinos left, mostly in South Africa, but they are 存在 relentlessly poached for their horns to 料金d illicit 需要・要求する in Asian countries such as Vietnam, where they are a prized 成分 in 伝統的な 薬／医学.
によれば the International Union for 自然保護 of Nature, there are around 900,000 Cape buffalo, also called African buffalo, on the continent but they are now mostly 限定するd to 保護するd areas. (令状ing by Ed Stoddard; Editing by James Macharia and Andrew Heavens)
