I'm a bit biased here at Kansas State :P
I'm looking to go into the same thing you are, and one option to consider is what you actually want to accomplish with equine reproduction. You don't NEED a DVM, you can get a Masters and work from there.
Colorado State is usually the first that comes up, but the problem is that as soon as you go, they have you on a "tracking program", meaning your classes are tailored to what you want to work on in the future, i.e. avian, equine, small animal, etc. Problem with that is it becomes harder to pass your Boards tests after you graduate, because you don't have rounded knowledge.
I love all the professors here, and the Dean is actually a good friends of my grandparents. I work in the hospital right now, and I will ONLY use the college for any work I need with my own horses
