Dr Duncan Prinsloo Senior made history in 1986 by doing the very first embryo transfer on a horse in South Africa.
At that stage no AI or Embryo transfer foals could be registered so our work was done on an experimental basis, until AI- & ET (embryo transfer) foals could be registered in the early 1990s.
Drs Duncan Prinsloo Snr & Jnr have traveled to Brazil, USA, Netherland, Belgium & France to stay up to date with the latest advances in the Equine Embryo Transfer industry, in an endeavor to render the best possible service.
We have flushed embryos from Warmbloods, Arabs, Friesians, Appaloosas, American Saddlers, Australian Stock horses, Boerperde, Hackneys etc throughout Southern Africa & as far abroad as Kenya.
Our Equine reproduction center in Gauteng is currently the only registered Equine AI & Embryo Transfer center in South Africa
We are also available to come and do embryo programs on-site at the studfarms throughout Africa.
Mares can be bred naturally by the stallion (either at pasture or in a controlled environment with the stallion in hand) or by artificial insemination (AI). Natural service is very common but carries an increased risk to the mare, stallion and mare holders or the stallion handler. It is not uncommon for pasture bred horses to receive injuries and many of these may result in fertility or behavioral issues for the stallion. AI is breeding of a mare with semen that has been collected and then inseminated into the uterus or vagina using instruments or equipment rather than by natural service. AI has been around for years, in fact the earliest report that we have seen (Jim Bowen in the USA ) quotes an Arab chieftain in 1322 stealing some freshly deposited semen and breeding his own mare. Only the Thoroughbred breed actively campaigns against its use: why is still a mystery to those who understand reproduction. AI can be used to breed mares with fresh semen or the semen can be mixed with seminal extenders and thus treated with antibiotics and cooled for 24-48 hours or frozen for AI much later on
We pride ourselves on the quality service that we render when it comes to training a stallion, collecting & shipping semen, or freezing semen.
Dr Duncan Snr spent a lot of time, energy & money to acquire the best techniques for especially semen freezing. He visited the USA (colorado state university), the Netherlands, Belgium & France to learn from world specialists in the field of semen freezing which techniques they use for different stallions. We have found that by using different freezing protocols (and patenting some of our own) that we can get the best possible post thaw mortality (amount of live semen) and motility (forward movement) to ensure good fertilisation when doing frozen semen AI. The difference between mediocre & good frozen semen is vast: with mediocre semen the inseminating vet is never really confident that he will get pregancies, especially in maiden mares, whereas with really good frozen semen one can even attempt AI on older mares & easily do Embryo transplants
Below is a video clip of frozen semen of just one of many stallions that we froze from. The semen is so good that we had to dilute the smear just to get a picture that is not too overcrowded. Feel free to call us for more info on freezing semen of your stallion
