Abstract

A 27-yr-old female pygmy hippopotamus (Choeropsis liberiensis) had two consecutive stillbirths with no overt signs of labor, suggestive of uterine inertia. After a third pregnancy was confirmed, an induction protocol was developed. Cloprostenol and betamethasone were administered on d 200 of gestation (time 0 h). Additional doses of cloprostenol were administered at 24 and 48 h and oxytocin at 30, 31, and 48 h. Each injection resulted in preparturient behavior without overt evidence of contractions. Fetal membranes presented at the vulva at 54.5 h after initial cloprostenol and betamethasone administration with no progression of labor. Transvaginal palpation and manual delivery of a live calf followed. Despite confirmed nursing, the serum glutaraldehyde coagulation test was negative. Failure of passive transfer may have been secondary to the induction protocol. The calf was treated with broad-spectrum antimicrobial agents due to diarrhea, and clinical signs resolved. This clinical brief details the first known induction of parturition in a pygmy hippopotamus, which can serve as the basis for further development of the technique.

诱导侏儒河马（choeropsis liberiensis）产仔。

一只 27 岁的雌性侏儒河马（Choeropsis liberiensis）连续两次死胎，且没有明显的分娩迹象，这表明它患有子宫惰性。在确认第三次妊娠后，制定了引产方案。在妊娠第 200 天（时间 0 h）给予氯前列醇和倍他米松。每次注射都会导致产前行为，但没有明显的宫缩迹象。首次注射氯前列醇和倍他米松后 54.5 小时，胎膜出现在外阴部，产程没有进展。经阴道触诊后，人工娩出了一头活牛犊。尽管确认了哺乳，但血清戊二醛凝固试验呈阴性。被动转移失败可能是诱导方案的次要原因。小牛因腹泻接受了广谱抗菌药治疗，临床症状有所缓解。本临床简报详细介绍了已知的首次侏儒河马催产，可作为进一步开发该技术的基础。

期刊介绍： The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers. The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution. Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
