The 2014 Gary Allee Science in Practice Symposium at the Midwest ASAS meetings will have two parts this year. The first part will feature speakers invited to discuss feeding sick pigs, and the second part will feature a panel and discussion around PEDv and feed as a possible vector of disease spread. Four speakers have been invited to talk about the challenges, costs, and some successes in feeding health challenged pigs. Dr. Nick Gabler, from Iowa State University, will discuss how Porcine Reproductive and Respiratory Syndrome (PRRS) impacts metabolism, body protein accretion and feed efficiency in grow-finisher pigs. Dr. Ryan Dilger, from University of Illinois, will discuss the metabolic events that occur during immune activation, and the physiological ramifications. Dr. Dean Boyd, from The Hanor Company, will discuss practices he has used through commercial application when feeding groups of health challenged pigs. Dr. Timothy Loula, from the Swine Vet Center, will discuss disease management from a Veterinarian’s point of view and the cost of disease and how he has worked jointly with nutritionists to help solve issues. Dr. Loula will serve as a transition from feeding sick pigs to a discussion on PEDv. He will continue his talk about what he has seen on the ground over the last several months. In addition to Dr. Loula, we have invited three others to be on a special panel to discuss PEDv, bringing in the latest information around PEDv, specifically as it relates to feed and nutrition. These are Bob Morrison DVM, a diagnostic Veterinarian at University of Minnesota, Noel Williams PhD, Chief Operating Officer at Iowa Select farms, and Henry Turlington PhD, Quality & Manufacturing Regulatory Affairs Director at the American Feed Industry Association. Each of them will respond to specific questions prepared beforehand, and then be part of an open discussion forum. The goal of this part of the Symposium will be to examine the scientific data available to aid in decision making around this very important topic to the swine industry.
