Fund Detail

This fund was formed to recognize the contribution of Dr. Gary Cromwell to non-ruminant nutrition and to the American Society of Animal Science. The money supports an award for outstanding research in the field of minerals nutrition. This award is given yearly at the ASAS National Meeting.

Gary Cromwell obtained a B.S. degree in agricultural education at Kansas State University and M.S. and Ph.D. degrees in animal nutrition at Purdue University. His entire 36-year research and teaching career has been at the University of Kentucky, where he is a professor in the Department of Animal Sciences. 

Cromwell's broad-based research has included the assessment of amino acid and mineral requirements of swine, the bioavailability of phosphorus in feedstuffs, copper as a growth promotant, the efficacy and safety of antibiotics, nutritional aspects of genetically modified crops, and environmental aspects associated with the use of phytase in swine diets. His research on phosphorus bioavailability has provided the basis for formulating pig diets on an "available phosphorus" basis. He is the author or co-author of more than 950 publications, including 139 refereed journal articles. He has directed or co-directed 61 graduate students, many of whom have prominent roles in the feed industry or academia. Cromwell served as president of ASAS in 1989-1990 and as nonruminant nutrition section editor of the Journal of Animal Science. He presently is chair of the FASS Food Safety Committee and the National Research Council's Committee on Animal Nutrition. He chaired the committee that prepared the 10th edition of Nutrient Requirements of Swine, in 1998. In 2002, he was the recipient of the Morrison Award.

2020 Recipient of the Gary L. Cromwell Award for Mineral Nutrition:

Dr. James C. Matthews, University of Kentucky

Dr. James (Jamie) Matthews has established a cutting-edge research program in mineral nutrition and physiology at the University of Kentucky using commercially-relevant experimental models. His research program has elucidated novel understandings of selenium and amino acid transport and metabolism that expands both production-animal and biomedical knowledge databases. His genomic and protein findings about how the expression and function of nutrient transporters and enzymes are coordinated is highly relevant to both the production animal and biomedical sciences. Importantly, 14 Ph.D., 7 postdoctoral, 13 M.S., and 22 undergraduate students have received significant to extensive training with Dr. Matthews in whole animal, biochemical, and molecular biology research techniques. Because of the extensive use of industry-relevant animal models, his basic research has the potential to have a rapid impact on development of nutritional regimens that optimize the performance of developing and mature animals.

2017 Recipient of the Gary L. Cromwell Award for Mineral Nutrition:

Dr. Xingen Lei, Cornell University

Dr. Xingen Lei received his B.S. and M.S. in China, and Ph.D. from Michigan State University. He was among the first to demonstrate nutritional and environmental values of supplemental phytase in improving feed phosphorus utilization. Lei developed a new generation of bacterial phytases that are used worldwide by the feed industry. Lei also pioneered nutritional genomics of selenium in pigs and chicks, and revealed dual roles of selenium in oxidative stress and diabetes. Lei discovered novel enhancers to improve iron nutrition of pigs. Lei authored over 400 publications, advised over 130 graduate students, postdocs, and visiting fellows, and served on panels for NIH and USDA, the NRC Committee on Mineral Toxicity, the CAST Task Force on Biotechnology and Manure Nutrients, and 9 Editorial Boards. Overall, Lei’s creative research on minerals has demonstrated clear benefits to animal agriculture and the environment.
