| Popis: | The captive greater one-horned rhinoceros population consistsof 176 animals. Since 1971, a total of 226 calves were born intothis captive population. However, 24% of the offspring bornwere either stillborn or did not survive the first 3 months. Thecauses for this high rate of stillbirth and neonate mortalityhave not yet been documented. Here, we report on theveterinary management of a dystocia and foetotomy resultingfrom a malpositioned greater one-horned rhinoceros foetus.The dead foetus presented with a forelimb flexed at theshoulder joint, with all other joints extended. The foetus wasdissected into five parts and extracted during two anaesthesiason two consecutive days. The dam recovered fully and cameinto oestrous 31 days after surgery. Post-mortem and CTexamination of the malformed foetal head revealed cranio-schisis with cerebral aplasia and cerebellar hypoplasia. Thecerebral aplasia presented here and in other recent casessuggests that neural tube defects and cranial malformationsmay be associated with more captive rhinoceros stillbirths thanpreviously considered. Epidemiologic studies of these phe-nomena and possible nutritional deficiencies or hereditarydefects are warranted. |
