March 17, 2010 — Dr. Derald Holtkamp

Dr. Derald Holtkamp provided the following update regarding the Production Animal Disease Risk Assessment Program (PADRAP) to the AASV Board of Directors.

Key Milestones & Upcoming Events

• The PRRS Risk Assessment for the Growing Pig Herd was released in June 2009
  • Database is currently being populated by student interns and small group of veterinarians
  • Benchmarking reports to be available when database is sufficiently populated
• PADRAP Online is being moved to Microsoft "dot-net" platform
  • Working with developers in Department of Veterinary Diagnostic and Production Animal Medicine at ISU College of Vet Med
  • New version of program will accommodate multiple languages
• Development of version 3 of the PRRS Risk Assessment for the Breeding Herd to be completed spring of 2010

Veterinarians Trained

• Web-based training sessions (via GoToMeeting.com) are being offered to veterinarians new to the program in lieu of face-to-face meetings
  • Web-based training sessions were previously offered only to those that had already attended an AASV sponsored training session to introduce them to the PADRAP Online. Face-to-face training sessions were required for veterinarians new to the program
• The training session now includes some instruction on use of the PRRS Risk Assessment for the Growing Pig Herd
  • Those previously trained on the PRRS Risk Assessment for the Breeding Herd are being given access to the PRRS Risk Assessment for the Growing Pig Herd when requested
• To date, 229 AASV members have been trained to use the PRRS Risk Assessments
• 35 PRRS Risk Assessment training sessions have been conducted in the U.S., Canada, Mexico and online
  • 18 online; 17 face-to-face
• PADRAP is being used primarily by veterinarians and researchers in the U.S, Mexico and Canada
• Veterinarians from Australia, Germany, South Korea, Netherlands and Bermuda have also been trained

Assessments Completed

• PRRS Risk Assessment for the Breeding Herd
  • 1981 assessments have been completed and submitted to the database of version 2 assessments for 1161 breeding herd sites (as of February, 2010)
• PRRS Risk Assessment for the Growing Pig Herd
  • 155 assessments have been completed and submitted to the database of version 1 assessments for 120 grow-finish sites (as of February, 2010)

Presentations/Reports

• 13 presentations on PRRS Risk Assessment program (from February 2009 to February 2010)
• 113 production system reports sent to veterinarians from February 2009 to February 2010 (34 PRRS-CAP Survival study; 5 non-study; 74 reports sent to PRRS regional eradication project coordinators)

Refereed Publications Related to PADRAP

• A prospective cohort study evaluating duration of breeding herd PRRS virus-free status and its relationship with measured risk. Holtkamp DJ, Yeske PE, Polson DD, Melody JL, Philips RC. Prev Vet Med. (Accepted, pending edits).
