Boy tough call...On one hand if cloning could be used to bring back lost breeds of horses or perhaps further an endangered breed. It could also be used to strengthen a breed that had been taken away from it's original foundation. However I would worry also that by using cloned horses for breeding purposes would drastically diminish the gene pool. Never mind if there truly are health issues, how many of those issues could be genetic and passed onto the offspring? I know I wouldn't want to breed my mare/stallion to a horse that was not healthy and didn't meet certain standards cloned or not.

This is a company that does cloning. Might have some more info for the OP. Either way I do not know enough about cloning to make a judgement call either way.

Thanks everyone.  I appreciate your input.  Has definatly helped me think through some new ideas.

Ride-now, you were right - the GP jumper named Sapphire that was cloned is a gelding. I stand corrected! I was not aware that there was another GP jumper named Sapphire other than McLain Ward's mount. But, the other day, I was flipping through my Practical Horseman and saw an ad for cloning - and, lo and behold, there was Sapphire. So, my bad! You were right all along.
