Every school sucks. The only good school is Harvard (it's DEFINITELY a vet school everybody, my cousin's mom told me!) and the prerequisite to get into THAT school is a DVM degree and a signed letter from the president that you've personally treated his Portuguese Water Dogs for super lupus. I also heard that their veterinarians resurrected Steve Jobs (people are animals too!) to do their site design himself.
All joking aside:
Pre-requisites don't mean much - they're basically some bare minimum knowledge that schools think will prepare you for a veterinary program. If you want to see a school with few prerequisites (possibly fewer than Mizzou), I invite you to take a look at CSU's list - it's pretty paltry as well. This means pretty much nothing about either program. Schools know what they want and honestly for any school prerequisites in general are fairly similar.
Don't worry too much about it (or the site design!). Frankly, based on a few of the vets I know, I would be dead impressed if any of them knew enough about a computer to even get a site running. Good site design can be nice, but remember that they're training you to be a veterinarian and the people in charge of a site's looks are usually either administrative or in a different department altogether.
