Improving the quality and digestibility of ethanol by-products for livestock feed is a major goal of Renessen, a joint venture between Cargill and Monsanto.
At the American Farm Bureau Federation annual meeting in Salt Lake City, Doug Rushing of Monsanto described how Renessen’s recently launched ethanol processing system, combined with a new corn hybrid, creates dried distillers’ grains (DDGs) with added value as hog feed.
The improved hog feed comes from lysine, an essential amino acid necessary for the growth and development of animals, which is an added biotech quality trait. The hybrid, called Mavera, also has twice the oil content of traditional corn.
The process cuts down the amount of DDGs produced by about one-third to one-half compared to traditional ethanol corn processing, but Rushing emphasizes that the DDGs are much more valuable to livestock producers who normally add synthetic lysine to rations.
The system is being used at a recently opened pilot ethanol plant in Iowa.

A University of Florida scientist is starting to see 20 years of research bear fuel.
A Malaysian company is building what it says is the world’s first plant to commercially produce ethanol from nipah palm trees.
The new chairman of the House Agriculture Committee made his first official appearance outside Washington at the South Dakota Corn Growers Association annual meeting Saturday, telling farmers that ethanol produced from corn and from new feedstocks such as switchgrass will be one of the forces driving a new farm bill in Congress.
Also addressing the corn growers was South Dakota Republican Senator John Thune who told the group that developing new feedstocks for ethanol should help the industry grow in other areas. “Corn ethanol is fine,” he said. The challenge for Congress: “Don’t screw it up.”
The demand for corn to make ethanol is expected to keep growing, which is creating challenges for livestock producers.
