Just curious, can you link your references? Saying it creates a deformity with out data to back it up doesn't make a lot of sense.
Not trying to be mean but if there is info out there I haven't seen I'd like to read it. Every "power fed" animal I've seen just looks like a fat sausage but definitely not deformed. I can see how it could possibly create underlying health issues or growth problems but there hasn't been any legitimate studies on it. And throwing this out there again, I don't agree with the practice and we grow our BPs up at an appropriate pace.
