Abstract

The drill ( Mandrillus leucophaeus ) is listed as endangered by the IUCN and its population is decreasing due to habitat loss and human activity. The European Endangered Species Programme (EEP) aims to consolidate a self-sustaining ex-situ population, and there is a need to develop appropriate assisted reproductive technologies (ART) that could help to increase breeding rates and/or genetic variability, or at least preserve sexual cells for the future. In 2006, a new breeding male drill arrived at Barcelona Zoo but was unable to mate appropriately with females during oestrus. Several attempts at sperm cell recovery by electro-ejaculation were performed on the breeding male in order to ascertain his fertility, while female oestrous cycles were visually monitored every month. In all, five electro-ejaculation and artificial insemination (AI) attempts were undertaken. Good samples of sperm were gathered and preserved, but the optimal moment for insemination needs more investigation, as no female got pregnant. To our knowledge, this is the first report of attempted AI in drills under anaesthesia and provides some valuable information for the future development of ART in endangered cercopithecids.
龙钻(Mandrillus leucophaeus)生殖评价及辅助生殖技术初步评价
世界自然保护联盟(IUCN)将孟钻(Mandrillus leucophaeus)列为濒危物种,由于栖息地丧失和人类活动,其数量正在减少。欧洲濒危物种方案(EEP)旨在巩固一个自我维持的迁地种群,并且有必要发展适当的辅助生殖技术(ART),以帮助提高繁殖率和/或遗传变异,或至少为将来保存性细胞。2006年,一只新的繁殖雄钻抵达巴塞罗那动物园,但在发情期无法与雌性交配。为了确定其生育能力,对育龄雄性进行了几次电射精恢复精子细胞的尝试,同时每月对雌性的排卵周期进行目测监测。总共进行了5次电射精和人工授精(AI)尝试。他们收集并保存了良好的精子样本,但受精的最佳时机还需要更多的调查,因为没有女性怀孕。据我们所知,这是第一次尝试在麻醉下进行人工智能的报道,为未来在濒危尾蚴中进行抗逆转录病毒治疗提供了一些有价值的信息。
