It really shouldn't be a problem on 500# calves if they are eating at least 1% of there body weight in a grain mix. They need energy to convert npn into microbial protein in the rumen. Or that is what I was taught but that was along time ago. I actually use 40% protein with 14% of protein from npn. Your other protein sources should have a high by-pass protein source though in the mix.
