Dr. Wayne Greene is Professor of Beef Cattle Nutrition and Production in the Department of Animal Sciences. Dr. Greene is currently teaching Introduction to Animal Science and graduate level Vitamins and Minerals, and Advanced Beef Production Systems. His research is focused on beef cattle production in both grazed and feedlot environments with an emphasis on nutrient utilization. He served as Professor and Department Head of the Department of Animal Sciences at Auburn University for 20 years. Prior to joining the Department of Animal Sciences he served a 23 year career in teaching, research and extension at Texas A&M University with joint appointments at West Texas A&M and Texas Tech Universities. Throughout his career, he has taught multiple courses in animal nutrition and conducted research in mineral metabolism of beef cattle. He has trained over 40 graduate students with M.S. and Ph.D. degrees, and published more than 500 scientific articles on beef cattle nutrition. Dr. Greene focuses his teaching and research program on mentoring students to develop the next generation of leaders that serve animal agriculture in food animal production. Dr. Greene has served his professional societies/organizations as President of the Plains Nutrition Council, Southern Section American Society of Animal Science, American Registry of Professional Animal Scientists and Alabama Coalition for Farm Animal Care and Well-Being. He is a Diplomate of the American College of Animal Sciences and certified as a Professional Animal Scientist. He is a Fellow of American Society of Animal Science, Regents Fellow of Texas A&M University System, and Faculty Fellow of Texas AgriLife Research. Dr. Greene has been awarded the Distinguished Service Award from the American Society of Animal Science - Southern Section, and the Distinguished Professoinal Animal Scientist Award from the American Registry of Professional Animal Scientist. Along with his duties in the Department of Animal Sciences, Dr. Greene currently serves as Scientific Advisor for Maxx Performance, Inc. andon the Board of Directors of the Southeastern Livestock Exposition.

Research

Research is focused on beef cattle nutrition in beef production systems. Specific research has focused on the mineral nutrition of beef cattle in grazing and fed environments. His work is recognized in areas of mineral supplementation to curtail the incidence of grass tetany, nutritional management to enhance environmental sustainability in cattle production facilities, macro- and micro-mineral nutrition to enhance animal health and productivity, interaction of feed additives and their use in beef cattle production systems.

Extension Experience

Extension and Outreach programs have focused on mineral nutrition needs of grazing cattle. This has involved one-on-one consultation with beef cattle producers to assess problems/issues faced in their production operation and the delivery of timely extension/outreach programs in support of beef cattle production.
