I graduated in '09 and did BIMS. Honestly I kind of regret BIMS. I thought it was too heavily based in theory and you didn't get enough hands on with the animals. I found myself taking more and more ANSC classes towards the end and I think I would've been happier, and perhaps salvaged a chunk of my GPA, had I just gone ANSC instead of BIMS.
I will say this, however: BIMS does a good job of preparing you for vet school. The transition was quite smooth even though I had a year long gap between the two. But then, the ANSC majors don't seem to be having a problem either so I'm not sure it matters much.
But if you do decide to go ANSC, be sure to take Physiology and Anatomy in your senior year (or whenever), as they'll help out tremendously to already have that background going in.
Oh and just for the record, it doesn't much matter which major you pick as long as you have all the pre-requisites, so if you want to do a major in, say, Business (I wish I had taken more business classes in undergrad personally), Entomology, Arts, Engineering, or whatever, go for it,, but you'll have to just plan out that much more what your schedule will be like.
One last thing: if you've any questions about A&M, vet school, BIMS, or whatever feel free to PM me. It might take me a few days to get back to you though.
