Synergies of Livestock and Ethanol
There is a lot made about tensions between the ethanol and livestock industries but the distillers grains co-product of ethanol production is providing significant benefits for animal producers even as ethanol has helped prop up corn prices.
A great discussion at the 6th Annual Iowa Renewable Fuels Summit featured corn and cattle organizations on the same panel talking about the “Synergies of Livestock and Ethanol.”
Moderator Iowa Agriculture Secretary Bill Northey opened the discussion by noting that sales of crops and livestock have risen as ethanol production has increased from $12 billion in 2002 – 6 billion in crop and 6 billion in livestock – to $24 billion in 2010, and 2011 is expected to be about $30 billion with at least $13 billion of that for livestock. “$13 billion on the livestock side versus $6 billion nine years ago,” Northey said. “Has ethanol been good for livestock agriculture in Iowa? I think very clearly.”

Iowa Cattlemen’s Association Executive Director Matt Deppe says it’s easy to see the benefits that distillers grains (DDGS) have brought to especially cattle feeders. “We look at it as a corn replacement,” Deppe says about DDGS. “It means that they (feedlot operators) have another option that’s cost effective to put into their rations.”

The livestock industry has traditionally been the most important market for corn, noted Iowa Corn Growers CEO Craig Floss, although use for ethanol has increased significantly in the past decade. “But a third of every one of those bushels that goes into an ethanol plant goes into DDGS,” he said.
The panel also included Randy Ives, director of ethanol services for the commodity management firm Gavilon Group.

According to the report by USDA’s Economic Research Service (ERS), “We found that, on average, for the past 5 crop years (2006/07-2010/11), 1 mt of distillers’ grains substitutes for about 1.22 mt of corn and soybean meal combined in the United States.”
Dr. Phillip Smith, a nutritionist with Tyson Foods, spoke at the recent
South Dakota State University Extension swine specialist Dr. Robert Thaler talked about the use of DDGS in hogs and how it helps supply phosphorus in the diet. “Phosphorus supplementation to the diet is very expensive,” he said. “The cool thing is that the phosphorus in DDGS is highly available. So, if you’re replacing dical or monocal with phosphorus coming from DDGS, you’re going to have less phosphorus in the manure, it will probably be cheaper and plus, you’re going to have less environmental problems.”
The ethanol by-product known as dried distillers grains, or DDGs, is being fed more often these days to all types of livestock. At first, it was mainly beef and dairy cattle producers that utilized the product, which is rich in protein, fiber and oil. Now more hog producers are using the product, which serves to recapture about one third of the corn that goes into making ethanol for the livestock feed market. Each bushel of grain used in the ethanol-making process produces about 18 pounds of DDGS.

The ethanol industry begs to disagree and contends that the livestock industry just wants cheap feed. “Once again, corporate livestock interests are seeking to return to the days they bought corn under the price of production for the American farmer. Such practices resulted in farmers getting more income from the government than they could from the marketplace, while corporate livestock industries prospered,” responded the 

“We walked through the B&I loan guarantee program, which has been used by their memberships, and we assured them that this was a long-standing program that we would use to help finance businesses in rural America, some of them may be ethanol facilities,” Schafer said. “We assured them that no specific money was being set aside only for the ethanol industry.”
