I don't know about Iowa state.
Many places that offer an Animal Science program though, offer a pre-vet option which is many of the classes you would take in an Equine Science program (not sure about Equine Studies) including Chemistry, Biology, Anatomy, MicroBiology, Econ, Etc. The school I was looking at was in CT and was paired with their Animal Science program. This way, if you decide not to go into Vet school then you can work towards finishing up a 4 year animal science degree. You will have most (if not all) your science classes done, hands on experience with various animals, and then will be working towards most of your related classes.
The program here in MT actually requires you take not only riding and farm management classes but also to work with cattle, swine, and sheep. If you look around, there are many different variations of them.
I'm giving my advice from a student currently in college, so bare with me.
If you're not sure if it is for you, perhaps look into volunteering with a veterinarian...they almost all need an extra pair of hands.
Regardless of what you decide to do, I definitely think the people at LJ need to get their panties out of a twist and get over themselves. I think they had good intentions in mind, but people tend to just get snarky on the internet. If I read right, and you're not sure about working with horses or becoming a vet, then maybe a broader animal science type think would be a good idea.
As far as Iowa state, I don't think anywhere requires that you have more than a BS before getting into the vet/grad program...
