Bing I did a similar test and found just the opposite. Mine ate GFC better. I still use both and up the % AM in the fall. The other advantage is the mixed sizes of GFC so even the little BG can eat. Now the LMB and HSB like the AM 600 better.

There are several studies that show 32% is plenty of protein for BG and IIRC no significant growth advantage to feeding higher % protein levels. I can dig those out if you like.

Deaner be sure your 75-D will throw AM 600 without jamming first.
