SHIC-FUNDED SYSTEMATIC LITERATURE REVIEW REVEALS JEV KNOWLEDGE GAPS

Jul 24, 2023

Due to the ongoing risk of Japanese encephalitis virus emergence in the US, the Swine Health Information Center funded a systematic literature review intended to increase understanding of the virus’s biology, components and dynamics of transmission, and environmental factors necessary for incursion and establishment. The recently completed systematic review is in addition to a separate JEV Risk Assessment funded by SHIC that is still in progress. As the US is considered a susceptible region with potential for the introduction of JEV, SHIC has focused on these projects designed to further strengthen US swine industry preparedness and inform response efforts, should they be needed.

Led by Dr. Natalia Cernicchiaro, Kansas State University, and in collaboration with researchers from the United States Department of Agriculture National Bio and Agro-Defense facility and the National Feral Swine Damage Management Program, the study synthesized existing information on the role of domestic and feral swine in the transmission of JEV through a systematic review of 228 articles deemed relevant in a process designed to identify knowledge gaps.

Video: Assessing Welfare Resources During Late Finish - Dr. Anna Johnson & Emma Coursey

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Anna Johnson from Iowa State University and Emma Coursey from the University of Illinois discuss research evaluating welfare resources during the late finishing stage on commercial swine farms. They explain how feeder management, water use, space allocation, and pig health influence welfare outcomes and practical on-farm management. Listen now on all major platforms!

"Small resource issues can become larger welfare problems when multiple stressors interact across finishing barns."

Meet the guests: Dr. Anna Johnson / anna-johnson-05028a14 is the Morrill Professor of Animal Behavior and Welfare at Iowa State University. She earned her Ph.D. in Animal Sciences from Texas Tech University and completed her master's degree in Applied Animal Behaviour and Welfare at the University of Edinburgh. Her research focuses on practical solutions that improve farm animal welfare, including sow productive lifetime, animal-human interaction, environmental enrichment, and Precision Livestock Farming.

Emma Coursey / emma-coursey-183810241 is pursuing a Doctor of Veterinary Medicine degree at the University of Illinois College of Veterinary Medicine after earning a bachelor's degree in Animal Science from Iowa State University. Her academic interests include swine health, production, and animal welfare, with research experience evaluating welfare resources in commercial finishing pigs.
