Vetnuus | September 2025 35 • Innovation: Development of concentrated butorphanol and fentanyl formulations, enabling reliable dosing via 2 ml darts. • Impact: Increased safety and effectiveness of immobilisation during lengthy procedures such as OPU, translocation, and dehorning. • Conservation Utility: These drug protocols can be applied more widely across rhino management operations. Conclusion The contribution of veterinary science, and specifically the work of Embryo Plus veterinarians, represents a transformational step in rhino conservation. These protocols—ranging from IVF and pregnancy diagnosis to genetic banking and safe anaesthetic techniques—address both immediate conservation needs and long-term sustainability of the species. This work is a true testimony to the dedication of South African veterinarians, whose science-driven solutions are not only helping to safeguard the Southern White Rhino but are also laying the groundwork for the conservation of endangered species worldwide. v We compound veterinary medicines www.v-tech.co.za / Tel: +27 87 150 5925 (SA) Article
