Corn Gluten Meal (CGM) – USA

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 ¼ kg) per cow per day due to poor palatability above these levels.
