FEEDSTUFFS IN FOCUS: Demonstration project evaluates viral survival in feed

Dr. Scott Dee of Pipestone Applied Research discusses how a new research procedure takes learning about viral transmission in feed from the lab to real-world situations.

In this episode, Feedstuffs editor Sarah Muirhead talks with Dr. Scott Dee of Pipestone Applied Research about a demonstration project conducted to evaluate viral survival in feed. 

A demonstration project is a new way of taking what has been learned in the lab and running a trial under more real-world conditions. In this case, Dee took samples of soybean meal, conventional and organic, lysine, choline and vitamin A that were all spiked with a mixture of PRRSV 174, PEDV and SVA and transported for 21 days in a trailer of a commercial transport vehicle. Samples were then tested for viral genome and viability at the end of the transit period. The demonstration project showed that three significant viral pathogens of pigs could survive in select feed ingredients during commercial transport, involving diverse environmental conditions and realistic transit period. Dee talks about the project and the results.
