Ditto the KSU, OkSU, TAMU, CSU. Maybe Iowa too? But honestly, if you go wherever is the cheapest/easiest for you, you'll get good production animal medicine. It's part of the curriculum anywhere, and there are more opportunities if you seek them out. There's not as much interest/competition either (compared to zoo medicine, small animal specialties, etc.) so you will probably get some more personalized attention (IMO).
