Robert Larson

Dr. Robert (Bob) L. Larson's research program focuses on improving the health, productivity, and sustainability of beef cattle systems through an integrated, applied approach that combines clinical veterinary medicine, epidemiology, and production management. His work emphasizes the intersection of animal health, biological performance, and economic decision-making, with the goal of developing practical, science-based strategies for cattle producers and veterinarians. A central theme of his research is the prevention, diagnosis, and management of major cattle diseases - particularly bovine respiratory disease (BRD) and other causes of morbidity and mortality in feedlot systems. This includes identifying risk factors, refining case definitions, and developing predictive models to improve treatment decisions and reduce losses. His work increasingly incorporates advanced analytics, including machine learning and precision livestock technologies, to support earlier disease detection and more targeted interventions. Dr. Larson also has a strong focus on reproductive efficiency and herd-level fertility, including evaluation of breeding soundness, heifer development, and management strategies that improve reproductive outcomes. His research integrates physiology with management practices to enhance reproductive success within the broader context of herd productivity. In addition, his work contributes to antimicrobial stewardship and evidence-based veterinary medicine, emphasizing the responsible use of therapeutics and the application of epidemiologic principles to clinical decision-making. He has been involved in multi-institutional collaborations aimed at optimizing metaphylaxis strategies and understanding disease dynamics in commercial cattle populations. Overall, his research is characterized by a systems-based perspective that links individual animal health to population-level outcomes and industry-wide impact, with a consistent emphasis on translating research findings into practical tools and recommendations for the beef cattle industry.
