At UC Davis, we have the following tracks (there are 9):
Equine
Equine/Small Animal
Food Animal
Food Animal/Small Animal
Large Animal
Mixed Animal
Small Animal
Zoological Medicine
Individual
8 species-specific tracks and 1 other, which it is my understanding is primarily used for folks who are interested in research, but I'm not totally clear on that yet.
I don't know where there might be one central location where you could get this info for all schools (I'd almost bet there isn't one). But here it is for Davis. 🙂
