I plan to do an ET with a 5 year old Hanoverian competition mare next spring. I have just found two recipients that neighbors who breed Quarter Horses will let me use. Both are 7 years old and have had two previous foals. They are big bodied mares that I think will be able to carry a Hanoverian safely.
What tests or other checks should I do on these mares to be sure that they are good candidates as recipients? I plan to use P&E to time my mare's breeding as well as the recipients' cycles.

I would check out which mare was the easiest breeder. They should have records on the breeding dates and what medical proceedures were neccessary to get the mares in foal.
See if you can have a look at the foals. One thing that is often overlooked, is the temperment of the mare. I would choose the mare that displayed the calmest attitude. That foal will learn many behaviors from the recipiant mare. Which foals were more easily halter broken and handled? You may be able to speak with whomever trained and handled the foals. Observe the mares and watch for undesirable vices, those too can be passed on.
Talk to the vet, he should also have records reflecting what was done to the mares during the breeding and foaling.
Both mares have no record of anything out of the ordinary needed to get in foal or maintain a pregnancy. The farm stands its own stallions and teases and then does live cover. Both mares are well behaved, have had nice, manageable foals, show no vices, are very easy keepers, etc.
I was really asking about what medical tests I should run on the girls before proceeding to the stage where we are actually synchronizing mares, etc. I assume that they have no problems since they had easy and successful pregnancies, but know that I should probably know more about them internally.
Assuming that both are good candidates, I will synch them both, as we may get lucky and get more than one embryo.

Although it is not overly likely to be an issue with a 7 year-old mare, it is still probably worth having a endometrial biopsy performed now before you make a commitment to take them. You will really kick yourself in the event that you end up finding that you have placed an embryo into a IIB uterus!
Other than that, a standard pre-breeding work-up is advisable prior to the transfer next spring - i.e. culture and cytology, plus ensuring that regular cyclicity is in place.
Which veterinarian are you using for your transfers? I am also doing embryo transfer this year (in your area) and will be using Maria Cadario and Equi Gen. They have a recipient herd of about 30 horses. Have you heard of them?
