New Corn Coproducts Fact Sheet Series Available from Iowa Beef Center


AMES, Iowa -- In an effort to extract more value from the corn kernel, new technological advances in the ethanol-making process have resulted in coproduct feedstuffs that are compositionally different from those produced through earlier, more traditional methods. Coproducts can be vital components of beef cattle diets, and Iowa Beef Center director Dan Loy said it’s important for producers to understand what’s available and how best to use them.

“The most abundant of these feeds -- distillers grains with solubles -- can vary widely in oil concentration due to the process used,” Loy said. “Moisture and nutrients also can vary depending on the plant and the process used. On the horizon is the increased use of technologies that may also extract corn fiber from the products.”

While all of these factors may impact the feeding value of ethanol coproducts for livestock, including beef cattle, it is imperative to highlight that these feeds still can have significant economic and nutritional value. Loy, who also is a professor in animal science at Iowa State University, said corn coproducts in Iowa and the upper Midwest can and do play a key role in economical and efficient beef rations, as long as research continues to evaluate the most effective use of these products.

“That’s why we developed this series of six new fact sheets on changes in coproducts and the subsequent effects on nutritional and economic value for beef cattle,” Loy said. “Each fact sheet provides specific relevant updated information on these changes and suggestions on how producers can effectively incorporate these changes into low cost effective nutritional programs.”

All six of the publications in this series, “Ethanol Coproducts for Beef Cattle,” have been peer-reviewed and offer the latest information based on research and demonstration projects, and all are available for download at no cost through individual links here

The Iowa Beef Center at Iowa State University was established in 1996 with the goal of supporting the growth and vitality of the state’s beef cattle industry. It comprises faculty and staff from Iowa State University Extension and Outreach, College of Agriculture and Life Sciences and College of Veterinary Medicine, and works to develop and deliver the latest research-based information regarding the beef cattle industry.
