Biosecurity intervention: Swine industry model
Biosecuring Animal Populations is a timely topic, based on the domestic and transboundary challenges of swine pathogens, such as African swine fever virus and porcine reproductive and respiratory syndrome virus (PRRSV) that threaten our livestock industries every day. This lecture will highlight data from the field, describing the efforts of veterinary practitioners and scientists to measure the impact of Next Generation Biosecurity (NexGenBio) interventions on the control of these significant diseases. NexGenBio has been described as a science-based, comprehensive approach to biosecuring the swine breeding herd through the coordinated application of biosecurity protocols to reduce the risk of direct routes of disease spread (infected pigs and contaminated semen) and indirect routes (mechanical/fomite-based routes, aerosols and feed). To describe whether NexGenBio can effectively reduce the impact of PRRSV across the Pipestone System, the 3rd largest pork production system in the US, encompassing >76 breeding herds and 350,000 sows, PRRS incidence data from a field-based project of significant size, scope, and scale will be reviewed across the period of July 2021-June 2024.
This session originally was presented at AVMA Convention 2024.
Learning Objectives:
- Learn about the swine industry's actions to monitor major swine pathogens.
- Describe ongoing efforts to measure the impact of NexGenBio interventions.
- Review field data that illustrates application of NexGenBio interventions.
Scott Dee earned a DVM, MS, and PhD from the University of Minnesota, is board-certified in veterinary microbiology, past President of the American Association of Swine Veterinarians, past Chair of the American Veterinary Medical Association (AVMA) Council on Biologic and Therapeutic Agents and currently serves on the AVMA House of Delegates. After 12 years in swine practice and another 12 years in academia, Scott joined Pipestone Veterinary Services as Director of Applied Research, where he served as Emeritus Director of Discovery and Innovation for Pipestone for 12.5 years. Throughout his career, he has been awarded >12.5 M in research funding and published 182 peer reviewed papers, including the initial publications on the proof of concept of PEDV transmission in feed and the transboundary survival of ASFV in feed. He developed the initial knowledge and industry-wide protocols to understand and control Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection at the farm level. The comprehensive application of these protocols has reduced annual PRRS incidence below 10% across the 76 breeding herds in the Pipestone System, the 3rd largest pork production company in the US, over a 2-year period. This is the first report of long-term control of PRRSV in a large-scale commercial swine production system and was published in the Journal of the AVMA. He received the AASV Practitioner of the Year, the Howard Dunne Memorial, and Leman Science in Practice awards, a Warrior Chip from the FBI, and is a Master of the US Pork Industry. He has guest-edited a Special Issue on Feed Risk in Transboundary and Emerging Diseases and is currently guest-editing another Special Issue on Biosecuring Animal Populations for the journal Animals. He has been awarded the Distinguished Service to the US Pork Industry Award from the National Pork Board and the Distinguished Service and Research award from the PRRS scientific community, recognized as the Distinguished Research Alumnus by the UMN College of Veterinary Medicine and is an honorary member of the Phi Zeta Sigma Veterinary Honors and Research Society at Kansas State University College of Veterinary Medicine. Scott is currently retired, and he and his wife Lisa live in Alexandria, MN. They have two children: Nicholas, a medical student at the University of Minnesota Duluth, Ellen, a CPA at Cargill, and Matilda, a 3-year-old Scottish Terrier.
