South African Vets pioneers assisted copy in rhinos


In a ground-breaking initiative, The South African Veterinary Affiliation (SAVA) and Rhino Repro have efficiently developed and applied assisted reproductive strategies for rhinos, a ground-breaking initiative to protect and shield rhinos.

Rhino Repro’s ground-breaking strategy encompasses the harvesting, maturing, and fertilization of oocytes (creating eggs), adopted by embryo switch into surrogate moms.

By optimizing these strategies on Southern White rhinos (SWRs), shut relations of the critically endangered Northern White rhinos (NWRs), the crew is paving the way in which for the long run preservation of the NWR species. Their final objective is to reap oocytes from the remaining NWR females, mature and fertilize them utilizing beforehand saved NWR semen, or make the most of banked NWR genetic materials and reconstruct embryos by means of nuclear switch (cloning) to generate a large-scale provide of embryos that may be cryo-preserved or transferred to SWR surrogate moms.

Our pioneering reproductive strategies are really a world first, providing a glimmer of hope for the endangered rhino species. By pushing the boundaries of scientific data and harnessing the ability of assisted copy, we’re decided to safe a future for these majestic animals,’ stated Dr Morné de la Rey, founding father of Rhino Repro and a visionary veterinarian main the crew.

Over the previous 5 years, the Rhino Repro crew has made vital progress in understanding the intricate reproductive anatomy of rhinos and has efficiently collected and matured oocytes from SWRs. Their state-of-the-art procedures have yielded spectacular outcomes, with a mean of 5.5 oocytes collected per process in 2022 and a record-breaking 18 oocytes collected from a single process.

Along with their vital deal with the NWR species, Rhino Repro’s modern approaches have proven promising outcomes for addressing breeding challenges confronted by different rhino species, reminiscent of SWRs affected by poaching stress and orphaned circumstances. Their revolutionary strategies have offered invaluable insights into the pure reproductive cycles of rhinos and have even contributed to bettering the reproductive well being of particular person cows, resulting in profitable pure copy in beforehand infertile or compromised rhinos.

The success of those world-first reproductive strategies depends on the assist and generosity of the general public and the broader enterprise group. Monetary contributions play a vital function in advancing analysis, increasing procedures, and rising the possibilities of producing blastocyst embryos.

‘Preserving the endangered rhino species shouldn’t be solely the accountability of the larger crew; it’s a collective endeavour involving your entire veterinary group and our nation as a complete,’ emphasised Dr Paul van der Merwe, President of the South African Veterinary Affiliation. ‘Collectively, we will pioneer world-first strategies that may safeguard the way forward for these magnificent creatures and go away a long-lasting legacy for generations to come back.’
