East African meso- and mega-herbivores have been a key part of the Earth’s ecosystem for millions of years, but are now at risk of disappearing. To ensure their conservation, operations that involve veterinary immobilization are becoming essential for wild populations. However, capture morbidity remains high, with both short- and longer-term physiological alterations that can result in acute or delayed death. In large-sized herbivores, the size and unique anatomy and physiology contribute to the high susceptibility to capture stress, drugs adverse effects and alterations due to recumbency. On top of this, the limited knowledge in the species-specific physiological response to immobilization and, as a result, the obliged practice of extrapolating drug doses and protocols from similar species, enhances the risk of complications. Improvement in capture methods and drug protocols are advocated, and as such, in order to develop targeted strategies, it is essential to gain a better understanding of the species-specific physiological impact of capture. The general objective of this thesis is to advance the knowledge of the physiological mechanism of capture morbidity, and evaluate strategies for the prevention, detection and treatment of complications arising from opioid-based immobilization of selected species of East African megaherbivores, the giraffe (Giraffa camelopardalis ssp. tippelskirchi and reticulata) and the black rhinoceros (Diceros bicornis ssp. michaeli), and in a large mesoherbivore, the African buffalo (Syncerus caffer). A key factor of this study was the collection of data through an opportunistic approach, whereas the research design was shaped for each of the study species based on targeted needs, thus different specific objectives were pursued for each species. In free-ranging Masai giraffes that were immobilized for a translocation, a combination of etorphine and azaperone was evaluated for physiological and handling safety. Early opioid antagonization – a common procedure performed to reduce ... |
