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: World Without Cows - Official Trailer

In World Without Cows, journalists Michelle Michael and Brandon Whitworth take viewers on a global journey to explore the essential role of cattle in agriculture, food systems, and rural economies. Through interviews with farmers, ranchers, and environmental scientists, the documentary challenges the growing wave of misinformation surrounding cattle and climate change.

Prompted by the rise of unscientific narratives that paint livestock in a negative light, Michael and Whitworth set out to tell a more balanced story—one rooted in evidence and lived experience. The film highlights the cultural significance of cows, their contribution to global nutrition, and the innovations within the industry aimed at reducing environmental impact.

World Without Cows is a compelling reminder of the complexity and importance of livestock in a sustainable future.
