As this will be her first pregnency you want a complete vet examination. You want to make sure she is perfectly healthy and in good physical form. You will also want a breeding exam to check her ovaries and uterus. She may take a bit longer to conceve, you will want regular vet checks to ensure she is in good health. Once she has cobceved you will need to keep an eye on her, as she is older and it's her first pregnancy, there are risks of complications and even her aborting the fetus. You will need to supplement her diet with a stud feed and possibly a veteran fees aswell. You also need to ensure that both mare and stallion are a physical match for each other. Meaning that they compliment each others conformation and neither have any drastic faults. Bare in mind that even the most stunning horses can produce an ugly foal if the have bad conformation in their genes. You don't want to stress her out by keep trying. if after the first few tries she hasn't taken, leave her til her next season and try again. Breeding can be a time consuming and sometimes unpredictable. Good luck.
I would get a breeding soundness exam on her, first. Just to make sure everything is okay. It might be harder on her since he is an older mare has never been bred before. I'm happy that someone that knows what there doing is breeding, not just some back your breeder. Those people make me so mad. Okay, I know you said not to give you the talk but I'm going to anyway. Please go get a nice, young, registered foal from the auction. You can save him/her from a bad home, save another horse from dying/being abused. Please. ]
