I agree with Josh, you don't want to be administering any vaccines 30 days prior to or after AI as they can have effects on a deer just as they would a person. You can see a slight increase in Body temperature among many other things, this is something you want to avoid when breeding season is upon your deer. Vitamins such as Vit. E and Vit. B will be beneficial for your AI, especially Vit. E as it has been proven in the goat industry to slightly increase egg production in does. I always tell people that I am going to AI for, stick with what has worked best for you in the past. If you haven't had good success, make small changes here and there to try and improve.
