 Corn gluten feed is a by-product  from the manufacture of cornstarch and corn syrup. It is a medium protein feed, which contains almost the same Total Digestible Nutrients level as barley. The protein in corn gluten feed is degraded relatively rapidly in the rumen. Corn gluten feed has medium palatability and may be included in the grain mixture up to a level of 50 percent or fed to cows at a rate of up to 5.4 Kg per cow per day.

Corn gluten meal is a by-product from the manufacture of corn starch and corn syrup. It is very high in protein supplement in feeds for livestock, poultry and pets. It contains slightly more TDN than corn. The protein in corn gluten is degraded relatively slowly in the rumen.  

Corn gluten meal usually is not included in mixtures at levels greater than 15 percent or fed at a rate greater than 15 percent or fed at a rate greater than 5 pounds (2 kg) per cow per day due to poor palatability above these levels.
