Authors Donald C. Beitz (Chair) is professor in the Department of Animal Sciences and Biochemistry at Iowa State University, where he has taught since 1977. He received his Ph.D. from Michigan State University. His research interests in- clude lipid metabolism in farm animals, ketosis in dairy cattle, and catecholamine metabolism in pigs. George C. Fahey is a professor of animal sciences and nutritional sciences at the University of Illinois, Urbana-Champaign. He received his Ph.D. from West Virginia University in 1976. His research interests include comparative carbohy- drate nutrition, ruminal and lower gut fermentation processes, and plant cell wall biochemistry as it applies to nutrition. Companion animal nutrition has been a recent focus of his research. Delbert Gatl~n III has served as the associate head of research and graduate programs for the Department of Wildlife and Fisheries at Texas A&M University since 1994. Since receiving his Ph.D. in 1983 from Mississippi State University, his research studies have included the nutrition of various fishes and shellfishes with a primary interest on species cultured for human consumption. Ronald L. Horst, an adjunct professor of nutritional biochemistry, is the re- search leader of the Metabolic Diseases and Immunology Research Unit, U.S. Department of Agriculture, Agricultural Research Service, in Ames, Iowa. He received his Ph.D. in nutrition from the University of Wisconsin at Madison in 1976. Research interests include the study of metabolism of vitamins A and D 79

Terry Klopfenstein is professor of beef cattle nutrition at the University of Nebraska. He received his Ph.D. from Ohio State University. Research interests include enhancing nutritional value of low-quality forage, crop residues for beef cattle, bypass protein sources for growing beef cattle, and alternative feedstuffs. Austin 'l. Lewis is a professor of nutrition at the University of Nebraska. He received his Ph.D. in 1971 from the University of Nottingham, England. His research interests include amino acid and energy nutrition and metabolism of all classes of swine. Carl Parsons is a professor of animal science at the University of Illinois at Urbana-Champaign. He received his Ph.D. in animal science from Virginia Polytechnic Institute and State University in 1981. His research interests include poultry production and management with emphasis in the field of nutrition and improved nutritional efficiency for the production of poultry meat and eggs, particularly with respect to protein utilization. Alice N. Pen is an associate professor of animal science at Cornell University. She received her Ph.D. in 1984 from the University of Vermont. Her areas of interest include the study of ruminant nutrition, ruminant microbiology, applied nutrition, and bovine somatotropin. Gary D. Potter, a professor of animal science and nutrition and the leader of the Equine Sciences Program, has taught at Texas A&M University since 1972. He received his Ph.D. in 1968 from the University of Kentucky. Research interests include equine nutrition, exercise, and physiology. Jerry L. Sell (Chair, Steering Committee) is a professor of animal nutrition at Iowa State University, where he has taught since 1976 and from which he re- ceived his Ph.D. in poultry nutrition in 1960. His major areas of research are dietary energy-to-amino acid relationships, amino acid requirements, mineral metabolism, and nutrition by disease interactions of turkeys and chickens. Karin M. Wittenberg is an associate professor at the University of Manitoba, Canada, where she received her Ph.D. in 1985. Her interests include investigat- ing new harvest storage technologies to improve feed value of conserved forage as well as evaluating the microstructural and biochemical techniques for plant breeding programs focused on digestibility.
