It depends on if you were adding nutrition to the live ones (called a gut load) or not. The dead ones are dehydrated, empty stomach contents (less overall nutrition compared to live/gut loaded) which is how that protein gets so high.
I use the dry as a treat to bring them home easier, but I don't rely on them to be the main protein source because they don't have any other nutrients in them. If that makes sense. You can give live ones a gut load of high protein starter or game feed, and sprinkle with calcium (for reptiles) to give to layers. Then simply serve less of them, to spread your supply a little farther.
If you're raising them they should have gut loads. It's the live ones that are store bought that do not have a gut load.
Or just mix the dried with the live, and give both, reducing what is coming out of your bins.
