I never figured out a way to *stop* heat, but I had one very hormonal mare that would come into heat when she saw a bay male (which meant that every competition we did was during a hormonal storm, since there are a lot of bays out there).  During breeding season I would stable my two bay geldings out of her sight and then shortly before trailering her to the stallion I'd put one of them in the adjacent paddock.  Sounds bizarre, but she'd be in receptive heat  shortly after arriving at the stallion, and get pregnant on that cycle.
