Part of it is the whole, we don't know what is destroyed by grinding freezing thing. If we need to supplement taurine, who is to say the other amino acids don't need a boost too?
Also, when I get a hedgehog (which is looking like it will be a very long time from now), its food will need to be cooked, so I would be more comfortable feeding cooked meat if I could add the amino acids back.
As far as the ca/ph ratio, it looks to be about 1.6 to 1, which is easily corrected by feeding some extra boneless meat.
