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.
A variety of corn gluten meal with 41 percent protein is available in some areas. It is higher in crude fiber (5 percent) and lower in TDN (78 percent) than the variety with 60 percent protein.
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.
Corn Gluten Meal (60% protein) is highly valued by the pet food industry and provides benefits to aquaculture feed as well. Corn gluten meal is used extensively by the poultry industry as a source of protein and xanthophyll. GPC corn gluten meal is used in poultry rations to produce poultry products with the healthy golden glow consumer’s demand. GPC can also supply Identity Preserved (I.P.) non-GMO corn gluten meal.

CGM is applied using a spreader or even by hand: the material is essentially harmless if not inhaled, and is, in fact, edible (though not particularly palatable). On lawns, CGM is applied in early spring (usually timed phenologically by the blooming of crocus or forsythia), and again in the autumn. If the lawn is overseeded, CGM should either be applied at least six weeks before sowing, or two weeks afterwards.
