Feed Additive to Mitigate the Risk of Virus-contaminated Feed

Publish Date: May 1, 2022

The introduction of Porcine Epidemic Diarrhea Virus (PEDV) in 2013 into the US swine industry pointed toward feed ingredients as the likely route of introduction. Subsequent research trials have documented viruses can survive in feed ingredients and complete feed for transoceanic shipping (30 and 37 days) and transcontinental shipping (23 days.) Authors of the transoceanic trial concluded: 1. Viruses can survive in feed, but survival is variable and depends on specific properties of each virus; 2. Certain feed ingredients or feed products present a better matrix for virus survival than others; and 3. Select ingredient matrices seemed to enhance the survival of multiple viruses. This fact sheet focuses on three research papers which evaluated compounds to mitigate virus-contaminated feed. The compounds are classified into two different groups. Foreign Animal Disease (FAD) viruses: African Swine Fever (ASF) and Foot and Mouth Disease (FMD); and Domestic viruses: Porcine Reproductive and Respiratory Syndrome virus (PRRSV), Senecavirus A (SVA), and Porcine Epidemic Diarrhea virus (PEDV) are discussed.

Challenges to Pig Health Improvement

Publish Date: June 3, 2006

I appreciate the opportunity to lead off this very interesting program. Thanks to Dr. Rodney Goodwin for the invitation. My task for today is two-fold: 1). To establish the definition of the healthy pig and to 2): To identify the challenges to pork production from an infectious disease point of view. My background consists of 12 years in a swine practice and now almost 5 years in academia doing applied research on the transmission and elimination of porcine reproductive and respiratory syndrome virus (PRRSV). Therefore, I will be addressing this issue from the position of an applied scientist who spends a great deal of his time in the field.
