What do you want to DO after college? If you hope to work at a very large breeding facility or research lab (breeding, genetics, 5 panel testing facilities, developing new pelleted feeds or injury therapy methods, etc.) then it may be a good option. If you want to work hands on with horses at a busy show barn, save your pennies and take on an internship with a trainer.
I have an Bachelor of Science majoring in Equine Science & Training. The experience was UTTERLY AMAZING and I learned more in those 4 years than 10 years of other experience! Classes focusing on breeding, genetics, nutrition, riding, facility management, crop management, business accounting & equine marketing, plus all the core Bachelor's degree courses.
All that said, I graduated in 2001 and I haven't worked in any agricultural capacity since 2003. My childhood dreams of making a living with horses didn't turn out the way I'd imagined, lol. I now work downtown in a corporate job to fund having a horse as a hobby, and I'm still paying off my student loans.
