Ethanol Byproduct Has High Energy, Fiber

The Joplin Globe:
Feeding dried distillers grain (DDG) in feed bunks to grazing cattle could mean more time on grass and less in feedlots.
The cost of animal gain is cheaper when cattle eat more grass and less $4-a-bushel corn in feedlots, said Karl Harborth, Kansas State University’s Southeast Area Extension livestock specialist in Chanute.
He spoke during a Beef Cattle and Forage Crops Field Day on May 3 at Mound Valley.
DDG is a byproduct of making ethanol.
Kansas has eight dry mill ethanol plants, including one at Garnett. Those plants create a market for more then 76 million bushels of corn and sorghum a year and produce 684,000 tons of DDG, according to the annual report issued by the KSU Southeast
Agricultural Research Center.
DDG has 25-30 percent crude protein, high energy content, high levels of fiber, low starch and is available, Harborth said.
On the down side, it has an average 10 percent fat content, variability of content, sulfur levels are questionable, storage is needed and availability can change, he said.
He provided information about tests where DDG was fed to steers grazing either native pasture or Bermuda grass in 2006 at Mound Valley. The DDG for the 2006 study was purchased at a price of $100 a ton. It was used as a supplement to steers grazing either native prairie or Bermuda grass pastures and is being continued this year.
