Professional Profile

Dr. Richeson became a faculty member in the Department of Agricultural Sciences and joined the Feedlot Research Group in 2011. He received his B.S. in animal science from Oklahoma State University in 2000, and spent two years working for a major cattle feeding company in Colorado. Dr. Richeson received a M.S. in ruminant nutrition from Texas Tech University in 2004, provided leadership of the Arkansas Beef Improvement Program from 2004 to 2008, and received his Ph.D. in animal science from the University of Arkansas in 2011.

Teaching and Related Service

Dr. Richeson teaches an undergraduate course in Anatomy and Physiology of Domestic Farm Animals and graduate-level courses in Advanced Animal Health Management, Research Techniques in Animal Science, and Agricultural Statistics.

Dr. Richeson is a member of the American Society of Animal Science and the American Registry of Professional Animal Scientists. He is co-advisor for the WTAMU Pre-Vet Club and manages the Ruminant Health and Immunology Laboratory on campus.

 

Research and Creative Activity

Dr. Richeson’s research interest involves the relationship of management, nutrition, physiological stress, and immunomodulation on the pathogenesis of bovine respiratory disease. Dr. Richeson and his graduate students evaluate respiratory vaccination strategies and the application of new technology and management systems to improve the health, immunity and well-being of beef and dairy cattle.
