Physical And Chemical Properties Of Corn Distillers Wet Grains, Kurt A. Rosentrater, R. Michael Lehman Jan 2008

Physical And Chemical Properties Of Corn Distillers Wet Grains, Kurt A. Rosentrater, R. Michael Lehman

Kurt A. Rosentrater

The production of corn-based ethanol in the United States is dramatically increasing, and consequently, so is the quantity of generated coproducts, all of which are currently fed to livestock. Distillers Wet Grain (DWG) is one of these coproduct feeds. Many studies have investigated the nutritional properties of DWG and the response of livestock (primarily beef and dairy) to inclusion of these ingredients in their diets. To date, physical properties have been largely ignored, but they are needed for the design of storage facilities and equipment. The objective of this research was to quantify physical and chemical property values for typical ...


Concentration Of Key Elements In North American Meat & Bone Meal, Rafael A. Garcia, Kurt A. Rosentrater Jan 2008

Concentration Of Key Elements In North American Meat & Bone Meal, Rafael A. Garcia, Kurt A. Rosentrater

Kurt A. Rosentrater

Meat & bone meal (MBM) and related rendered protein commodities have potential for use in applications other than animal feed, including use as a fuel or a phosphorus fertilizer. In order to develop these applications, data on the elemental composition are required; the currently available elemental composition data have important limitations. To generate more appropriate and reliable data, MBM samples were collected from 17 North American rendering plants, carefully prepared and analyzed for 20 elements. Preliminary studies showed that the sample preparation process artificially increased levels of sulfur and nickel in a manner that was correctable. Concentrations of many elements were found to agree with previously published values, but concentrations of potassium, magnesium and copper were significantly different from the most authoritative reference. Concentrations of heavy metals tested for were low, and arsenic and cadmium were not detected in any sample ...
