AASV Committee Meetings
7:00 AM - 12:00 PM

Web-based PRRS Risk Assessment Training for the Breeding Herd
7:30 AM - 12:30 PM
Coordinator: Derald Holtkamp

Fee: No charge
Limit: 20 participants (AASV membership required)

This training will guide you through the use of the web-based PRRS Risk Assessment known as the Production Animal Disease Risk Assessment Program (PADRAP). PADRAP allows you to view benchmarking reports immediately after submitting an assessment. The website underwent a “facelift” in May 2011 and gained a few new useful features.

Three ways veterinarians have applied the PRRS Risk Assessment:

· Evaluate current biosecurity protocols and/or develop new biosecurity protocols to avoid risk

· Communicate risks and the importance of biosecurity procedures to clients or production personnel

· Aid in the decision to initiate a project to eliminate PRRSv from a breeding herd site and identify modifiable risk factors in an effort to increase the likelihood that an elimination project will be successful long-term.

This session is open to AASV member veterinarians who have not previously used the PRRS Risk Assessment, as well as those who have previously been trained on the spreadsheet version. Please bring a laptop with MS Windows 2000, XP, Vista, or Windows 7 capable of accessing the internet via wireless connection.

Seminar #1: Purpose-Inspired Practice Tips
Seminar chair: Jay Miller

Purpose-Inspired Practice Tips will once again be an exciting, interactive, ideas-sharing session. There will be ten veterinarians competing for the big dollars for the practice tip with the “most impact” to our industry. The expert judges will be given the task to pick the practice tip with the most benefit to the practitioner and/or the producer.

Seminar #2: It's Not All Bugs and Drugs
Seminar co-chairs: Randy Jones and Rodger Main

Not all clinical disease that practitioners encounter on a daily basis is due to infectious agents. Numerous production inputs, stressors, and toxins can cause “disease.” Determining an accurate diagnosis on these, often multi-faceted, cases can be challenging and require the use of diagnostic tools and methodologies that go beyond the traditional “test and report.” This seminar is designed to give practitioners the tools and knowledge needed to work up these atypical cases, and to present and discuss some recent cases as examples.

Seminar #9: Swine Med for Students
Seminar co-chairs: Angie Supple and Jeremy Pittman

This year’s student pre-conference seminar is a continuation of last year’s session, which focused on differentials and diagnostics. Now that you know what “bugs” are there, we will explore the “drugs” that can be used to treat and prevent them. Areas we feel are opportunities for veterinary students and recent graduates include getting familiar with what products are available, how to select and develop antibiotic and vaccine protocols, and common “field” mistakes and tricks encountered. The first half of the session will be focused on these aspects, while the second half of the session will be a set of interactive case studies where groups of students will develop treatment or vaccine protocols based on a provided case example, using the knowledge gained in the first half.
