Corn gluten meal (CGM) is a byproduct of corn (maize) processing that has historically been used as an animal feed. The expression “corn gluten” is colloquial jargon that describes corn proteins that are neither gliadin nor glutenin. Only wheat, barley, and rye contain true gluten, which is formed by the interaction of gliadin and glutenin proteins.
Since corn gluten meal in different usage and different production process has different nutritional ingredients, it directly affects the effective availability and economic benefit of feed formula. The protein content of corn gluten meal produced in medical industry is up to more than 60%. It is respectively 21% higher than bean cake and 3.7% higher than fish meal. It is a kind of feedstuff with high content of protein. Meanwhile, its crude fiber content is lower than 3．9% bean cake. The fat content of medical corn gluten meal is higher than bean cake and corn. After it is mixed into feed, it is with high fat content and in favor of reducing the amino acid oxidation and generated ribosomal protein, and also can restrain glucose and other fat transformed by precursor substances; under high temperature, it is also beneficial to energy intake, reduces body heat consumption of beasts and birds and is slow down heat stress.
Corn gluten inhibits seeds from forming roots during germination. The application must be carefully timed before germination of crabgrass seeds, for instance. The seed will germinate and form a shoot, but not a root. Prior to germination, a short drying period is needed to kill the germinated, but rootless, plant. If conditions are too wet during germination, the plant will recover and form a root.
Corn gluten provides no post-emergent weed control. If seeds have already germinated, a late application of corn gluten will only serve as fertilizer for the weeds.
Applications of corn gluten should be timed with rainfall. If it doesn’t rain within five days of application, it needs to be watered in with 1/4 inch of water. A dry period of a day or two must follow the watering in to prevent the seedling from growing another root.
Downside of Using Corn Gluten
Corn gluten is costlier than conventional pre-emergent herbicides. Because multiple applications are often required, you could be handling hundreds or even thousands of pounds of the product, depending on the size of the yard. Sprayable, liquid forms of corn gluten can make applications easier but are still costly.
Timing is critical for both organic and synthetic chemical pre-emergents. It’s very important to remember that all pre-emergents suppress seeds, including grass and flower seeds. When using non-selective pre-emergents, most of the seeding needs to be done in the fall.
CGM is used as an inexpensive protein source for pet foods. CGM is an especially good source of the amino acid cysteine,but must be balanced with other proteins for lysine.
It is commonly used as livestock feed, including poultry and fish. It is a good source of protein, energy and pigments.
1.Good quality on the aspect of color, moisture and protein
2.Provides with various amino acid,vitamin and micronelement
3.Good purified materials improve the growth and disease resistance of poultry and livestock
