As one of the premier research programs at UNL and nationwide, his findings have had a tremendous economic impact on cattle feeding in Nebraska and the nation. Terry was a pioneer in using corn byproducts from the ethanol and sweetener industries to supplement cattle feeding creating a win-win-win scenario for cattle feeders, grain farmers and the milling industries. Principles learned in the evaluation of protein sources, protein requirements and growing/finishing systems have been used by the feed and livestock industries. Research with grazing and treating crop residues have been adopted by cattle producers both within the US and internationally. Terry has authored over 300 refereed articles and over 1000 abstracts and technical articles.
