In our experience success with frozen semen is a function of the experience and success rate of the vet doing the reproductive work. There is a huge range of competence with veterinarians. We have seen breeders waste a fortune on vets who simply do not really know what they are doing and/or do not do the procedure often enough to ever get good at it. Arthur is an OBGYN… like any area of medicine, the more you do a procedure successfully, the better you are at it. We use a vet here in the USA who is excellent, with an excellent rate of success. He got our 22 year-old mare in foal on one dose of frozen semen (Lord Sinclair), successfully harvested the embryo (producing our 2005 Lord Baltimore http://logresfarm.com/Lord%20Baltimore.htm ) and then got the 22 year old mare back in foal, again on one dose of frozen (from Sandro Hit). I should mention that this mare had her last foal at 26, so we concede that she had excellent reproductive health… and we provided an optimum environment for her.
About San Amour, our concern has to do with his movement, and what we see in his foals. To be blunt, we’d like to see the horse come under themselves better and engage the rear more actively. Other than that, we like many things about San Amour.
Re Sarkozy, watch him come straight at you… there is just not a lot of him, most especially he is very narrow, for that matter, so is Sandro Hit. I think that you have to be careful that the mare you put to these boys has sufficient body (and then some).
Btw, we value a versatile horse and look for good jumping scores as well as dressage scores, which is one reason we bred to Contango in 2003 (which produced Commander http://logresfarm.com/Commander.htm). You might look at Daddy Cool, he is on Schockemöhle’s website.
If you are breeding for yourself I think you tend to be much more careful about each and every aspect of the breeding because it will directly impact performance in later years. You may well do best with some obscure stallion who perfectly suits your mare. In contrast, if you are breeding to sell, i.e. to produce a marketable foal then all you really need is a pretty foal from the hot new stallion of the moment (e.g., Sandro Hit, Rotspon, Florencio, Hotline, Quateback, Diarado etc. )… and some pretty foal photos. Actual performance years down the road doesn’t really seem to factor in to this kind of breeding / marketing. So whether the breeder is keeping the foal or selling it makes a significant difference in stallion choices.
