Much different than DDG which is byproduct of ethanol manufacturing (use to be primarily from high quality whiskey distilling. lol). DDG is a much higher quality product ranging in crude protein from 25% to as much as 34% and containing fat levels as high as 15% in some cases. Corn gluten feed will vary from 14% crude protein up to as high s 21% in some instances but most of the fat has been removed thus it has much lower net energy values than DDG and is considered more as a simply grain by-product. Just a personal opinion but I have very high regard for DDG but Corn gluten always hits me as sort of a "last resort" feed ingredient. Both work well when used properly and can be very cost effective.
