PEDv Update

Mar 28, 2014

University of Nebraska-Lincoln Veterinary Diagnostic Center has provided guidelines for submitting PEDv samples to the lab for PED diagnostics.
KSU provided a link to a suggested protocol for feed sample collection and an evaluation of possible technologies to reduce feed contamination with PEDv.
National Pork Board appropriated $650,000 for PEDv research, American Feed Industry Association (AFIA) also provided an additional $100,000 to investigate feed related issues. Genome Alberta is contributing $500,000 for collaborative research.
AASV, NPB and NPPC met with feed industry representatives in March to discuss research needs relative to feed and ingredients as a potential vector for the transmission of PEDv.
- VDLs and researchers have looked at a number of PCR positive samples using bioassay and haven’t been successful showing a connection
  - Sample retention questions
  - Sensitivity of the bioassay – testing few animals for what may be a low (but not zero) risk of transmission
  - Testing methodology questions
Canadians were able to infect pigs using contaminated porcine blood products but not finished feeds
Scott Dee is reporting success using bioassay and feeding pigs for a longer period of time.
The New Case Report for the week ending 3/22/14 has been posted on the AASV PEDv web page. The NAHLN reports 266 positive accessions out of 825 tested at 9 Veterinary Diagnostic Labs. In addition, they adjusted last week’s number down to 291 from 296. This maintains the general downward trend in positive case submissions. No new states reported a confirmed case.

Video: Special Considerations for Grazing Sheep

Presented by Christine O'Reilly

Many Canadian grazing recommendations were developed using beef cattle in the prairies. While we have adapted these the forage species and climate in Ontario, other livestock have different needs. Public enemy number one for grazing sheep are gastrointestinal parasites.

The purpose of the Profitable Pasture conference is to bring fresh ideas and new research results to Ontario grazing managers across the ruminant livestock sectors. These conferences have a major focus on pasture management.
