Research Program

Environmental Aspects of Swine Nutrition

Dr. Radcliffe's research focuses on "environmental nutrition" in swine and poultry. Specifically, his lab is investigating dietary additives that reduce nutrient excretion and that might serve as potential replacements for subtherapeutic levels of antibiotics in the diet. In conjunction with this research he has been involved in the development of a steered ileo-cecal valve (SICV) cannulation technique that is used in pigs to collect ileal digesta and determine amino acid digestibilities. Students in his lab will be exposed to a wide range of laboratory techniques and will be asked to address research areas on both an applied and a basic level.
