Corn Co-Products

The National Corn to Ethanol Research Center (NCERC), at Southern Illinois Univ. - Edwardsville, is measuring nutrient levels monthly from samples of dried distillers grains with solubles (DDGS), corn gluten feed (CGF), and corn gluten meal (CGM) from participating ethanol plants.


This is a collaborative project of The Illinois Corn Growers Association, Western Illinois University, University of Illinois in Champaign/Urbana, and the NCERC working with the livestock industry to ensure an economical and nutritious ethanol co-product feed supply for producers.
