High Mortality Syndrome in Growing/ Finishing Pigs

Recently, our industry has concerns with increased mortality in growing
pigs. The increased mortality is often associated with PMWS-like
features. The American Association of Swine Veterinarians has partnered
with the Purdue University Regional Visual Analytic Center (PURVAC) to
develop a tool to better understand this syndrome. PURVAC’s tool enables
geographical and temporal visualization of disease syndromes and
potential risk factors. PURVAC currently uses similar tools to monitor
human health challenges and has volunteered to custom design a tool for
the pork industry at no cost. However, we must provide the data for them
to develop the prototype tool. ALL data collected will be held strictly
confidential under a confidentiality agreement with AASV and Purdue
University. The information submitted will not be made public and cannot
be accessed using the Freedom of Information Act. The only people that
will see the raw data will be designated representatives of AASV and the
Project Team at Purdue. We would like to thank the Checkoff National
Pork Board for bringing together an expert group of veterinarians and
PMWS researchers that provided case characteristics that are adapted for
this survey. We hope that you choose to participate so that we can give
our industry one more tool in the fight against emerging disease syndromes.
