Wisconsin Aids Australian DDGS-Feeding Trial

Trial being supported by Wisconsin company and organizations.

A donation by The DeLong Company Inc. of Clinton that helped ship U.S. distiller’s dried grains with solubles (DDGS) to Australia is paying off with positive feeding results by Australian dairy producers.

DDGS are a high-protein animal feed and a co-product of U.S. ethanol production.

Preliminary feeding trials conducted by Australian feed supplier CopRice with support from the U.S. Grains Council show DDGS can be included in dairy rations up to 20 percent without any adverse effect on milk production. In addition, milling trials showed DDGS can be included in pelletized high protein, high energy rations with no negative impact to the milling process.

CopRice contracted with two farmers, each milking 450 to 500 cows, totaling nearly 1,000 cows. Inclusion of pelletized DDGS was 0%, 5% and 10% at one farm. At the other, the inclusion was 0%, 5%, 15% and 20%. Rations were formulated to the same energy and protein contents as those without distiller’s grains. Upon completion of the trial, CopRice measured milk volume and output per cow, milk fat and milk protein content. Results, compared to a control diet, indicated no negative impact on milk production.

The study offers potential for DDGS in Australia, according to Adel Yusupov, USGC regional director in the area. He said DDGS prices in Australia depend largely on shipping cost and if they prove price competitive Australian end-users will incorporate the co-product into feed formulations.

The Wisconsin Corn Promotion Board provides funding for USCG marketing initiatives through the state corn checkoff program, which collects one-half cent for every bushel of Wisconsin corn sold. The primary objective of Wisconsin’s corn marketing order, which has been in place for more than 26years, is to maintain and expand sales of Wisconsin corn. WCPB President Ken Rosenow serves as Wisconsin’s representative to USCG, a private, non-profit partnership of farmers and agribusinesses committed to building and expanding international markets for U.S. corn, other feed grains and their products.
