As far as a food that is appropriate for large breed growth and in regards to protein levels, meat has a lot of phosphorus in it naturally and the calcium/phosphorus ratio has to be in a certain range, so to keep the calcium low enough, they have to use meats that are low in phosphorus and/or limit the amount of meat. That’s why the really high protein foods aren’t on the list.
When I say some people have a personal limit of 30% protein, I mean they won’t feed a food that has less than that. I am however referring to dry matter, not guaranteed analysis. If you want to keep the calcium/phosphorus balanced but add more protein to a meal, tripe is the way to go. Not the bleached tripe that the butcher or grocery store sells though, green or canned tripe.
