2007 Gamma Sigma Delta Research award

Dr. Arnold Hippen was presented the Research award of the SDSU Chapter of Gamma Sigma Delta at their annual awards banquet on 17th April. Dr. Arnold Hippen is an Associate Professor of Dairy Science. He has been a Dairy Science faculty member since 1998 when he joined as Assistant Professor under the David H. Henry sustained Professorship. During his tenure at SDSU, Dr. Hippen has established an outstanding, research program in dairy cattle nutrition. Since 2001 he has been PI or co-PI of 22 research projects of just over $800,000 resulting in over 70 publications. These include refereed publications, abstracts, proceedings, presentations, book chapters and a patent pending. Dr. Hippen has distinguished himself in the area of dairy cattle nutrient management influencing productivity and production efficiency, nutrient management, and general management strategies all with the goal of increasing profitability for dairy producers. This work and his on-going research work in applications of distillers grains in dairy cattle diets has successfully contributed new practical knowledge for dairy producers. Dr. Hippen’s research program focuses on contemporary agricultural trends in the state and the region. Thus, he has linked his research activities to the growing alternative fuel industry in the state. A good example of this is his research work with distillers grains. Further, he has also been involved in studies that are evaluating the use of glycerol, a by-product of biodiesel manufacture, for the prevention of fatty liver and ketosis in dairy cows. His distillers grains research program includes 1) strategies to increase the amount of distillers grains in the diet, 2) study of long-term effects of corn distillers grains in diets, 3) distillers grains as a component of calf diets, 4) study of germ predistillation fractionation of corn grain for ethanol production as a supplement for dairy cows. Dr. Hippen is currently also directing a research project that is determining mechanisms and efficiencies of methods to increase the content of “healthful” fatty acids in milk. These studies combined, will provide most valuable practical information to dairy producers. Dr. Hippen has served as mentor to a recipient of the Griffith Undergraduate Research Award, and the Joseph F. Nelson mentor program. At least 5 undergraduate students have developed research programs under his mentorship over the past five years. He is an active participant in and has played leadership roles in multi-state regional projects, NC 1009, Metabolic relationships of nutrients and NC 1119, Management systems to improve the economic and environmental sustainability of dairy enterprises. Dr. Hippen chairs the SDSU Institutional Animal Care and Use Committee.
