I figure it would be more brain size than intelligence. I would expect pain would increase by having more neurons to feel it, not having a deeper understanding of what it is.
Beef-only has the opposite problem. If not all creatures suffer equally, avoiding cows would be most important.
Also, I found the article. If those numbers are somewhat correct, maybe add an adjustment for brain mass to it? But just from rough guesses at the affect that would have, I see why going for medium-size animals makes sense.
