Improving digestibility of corn stover, other feed alternatives
With 2012 bringing one of the warmest and driest April-through-July stretches in more than 100 years, pastures, crops and even established trees are suffering from the drought. In response to the reduction in forages, some cow-calf operators are considering significantly reducing or liquidating their herds.
For those livestock farmers struggling to find feed sources, Justin Sexten, University of Missouri beef nutritionist, the Missouri Corn Merchandising Council and the Missouri Cattlemen's Association are working together to explore alternative forages. The coalition will be hosting workshops around the state to demonstrate how to improve digestibility of corn stover and lower-quality hay by 15 percent while doubling the feeds' protein content.
Incorporating a specific treatment process called ammoniation, producers can treat corn stover at a cost of approximately $25 per ton of forage. The added nutritional value makes it an economical choice in a season filled with climatic and economic challenges. To help walk producers through the process, the university and the state's corn and cattle organizations are offering free workshops in select regions.
"The livestock industry is our No. 1 customer," said Gary Wheeler, vice president of operations and grower services for Missouri Corn. "Through these free forage demonstrations, we are working to help connect corn growers with cattlemen for the good of all parties involved."
Sexten will also demonstrate treatment of processed corn stover with calcium hydroxide. Similar to ammoniation, stover digestibility is improved with this process and the protein content remains unchanged.
Farmers interested in purchasing or selling corn stover, cornstalks or hay as a feedstock are encouraged to visit the following online forage directories: agebb.missouri.edu/haylst, www.mocattle.org/haydirectory.aspx, and mda.mo.gov/abd/haydirectory.
