The ethanol industry is rapidly expanding. As much as 40 percent of the energy cost is associated with drying of the feed co-products. Distillers grains are excellent sources of nutrients for the diets of beef cattle, but have a short shelf life. To expand the use of wet distillers feeds to more producers, longer term, low-cost storage methods are required. Studies done in 2006–2007 showed that bagging these products was an effective management practice, but was higher in cost than acceptable to some producers. Additionally, availability of bagging equipment is limited, thus encouraging other storage methodologies to be investigated.
