I have only used vets here. I can't see having someone who is not a vet do the work. When your most prized bucks are laying on the table why would you not want a qualified vet on hand? I have used Dr Bringans, Dr Gorley and Dr Favero. I love the way they not only collect the semen but also monitor the health of the buck while collecting. I listed the 3 vets that have been here, but that is not to say that others like Dr Shipley and such wouldn't be just as good.
