The Director of Research with Pipestone Applied Research is confident a simulation model which shows pathogens responsible for disease in swine can cross the ocean in feed ingredients will stimulate discussion on action that might be necessary to reduce the risks associated with imported feed products.
Research underway at South Dakota State University, in which scientists are simulating the movement from China across the ocean to Iowa of feed ingredients contaminated by microorganisms, shows imported feed ingredients are capable harboring the pathogens that cause disease in swine.
Dr. Scott Dee, the Director of Research with Pipestone Applied Research, a part of Pipestone Veterinary Services, says the study started out by looking at feed ingredients inoculated with PED virus and has been expanded.
Dr. Scott Dee-Pipestone Applied Research:
Similar to what we saw with PED work, products that are soy based seem to be very supportive for what ever reason.
Lysine seems to be repeatable, choline seems to be repeatable and it seems to also depend on the structure of the virus.
If the virus is very stable, it's living longer.
If they virus is very labile outside the host, for example it dies quickly, dries out, those don't make it across the ocean so to speak.
What we hope to do is a couple of things.
Just raise the awareness that feed ingredients could be risk factors for disease transmission.
