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

Web-based PRRS Risk Assessment Training for the Breeding Herd
Coordinator:  Derald Holtkamp

Limit: 20 participants (AASV membership required)
7:30 AM – 12:30 PM

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.

Entrance Examination: American Board of Veterinary Practitioners (ABVP): Swine Health Management
8:00 AM - 12:00 PM

Seminar #1: Applying Evidence Based Medicine (EBM) in Practice
Seminar co-chairs: Alex Ramirez and Darin Madson
1:00 - 5:00 PM

This seminar is focused on improving the implementation of evidence-based medicine (EBM) in swine medicine. The workshop will be centered on field applications of EBM, not institutional research. Individual and group discussion will be solicited to help guide EBM concepts in both a simple as well as a complex field scenario. After a brief, interactive introduction, individuals will be split into groups. Each group will be facilitated by a member of a practitioner panel recruited to help with this seminar. Groups will work on discussing how they would implement a field trial in their practice to provide evidence on the effectiveness of a new vaccine. A second group activity will involve a more complex clinical problem (Mulberry Heart Disease mortality). This complex problem will be broken down into smaller parts focused on decision-making based on evidence. How do you define the problem? What information is already known? How do you decide on prioritizing interventions as well as how do you monitor the outcomes of the interventions? The goal of this workshop is for participants to understand what EBM is as well as to be aware of how to better implement and interpret information/results from studies (institutional research as well as field research). Ultimately, this workshop will help practitioners improve their implementation of EBM in swine practice.

Seminar #2: Preventing Profit-Robbing Events in Growing Pig Populations
Seminar chair: Mike Eisenmenger
1:00 - 5:00 PM

In today’s competitive environment, we can’t afford to give away profit by allowing preventable profit-robbing events to happen. This session will feature speakers that have “real life” experiences to share. They have dealt with these events and have solutions for you to take home to prevent them from occurring in work or practice.

Speakers will focus on ventilation events that cause dead pigs as well as the science behind why this happens, biosecurity practices that lead to sustainable health, lessons learned in the transportation of weaned pigs through market loads to prevent deaths, and finally, a focus on feed-outs and nutrition as it relates to preventable losses.

You should leave this session with clear ideas and strategies on how to prevent loss events centered around feed, water, air, biosecurity and transportation.

Seminar #4: Providing Solutions with Impact: Practice Tips with a Twist
Seminar chair: Jay Miller
1:00 - 5:00 PM

Have you attended or participated in the fun and interactive “practice tips” idea-sharing session? This pre-conference seminar takes practice tips to a new level by providing a panel of expert judges that will select one of the presentations to receive the “most impact” award, replacing the audience vote used in past years. Eight veterinarians will present a case, project, or experience they feel would impact the attendees by providing a new solution or approach to a problem. As in the past, these busy veterinarians have not been required to write a paper. The wide range of possibilities for new ideas is sure to provide some take-home solutions with impact!

Seminar #6: Applied Diagnostics and Algorithms
Seminar chair: Eva Jablonski
8:00 AM - 12:00 PM

To start the seminar, two expert diagnosticians from Iowa State University and the University of Minnesota will team up to share step-wise diagnostic algorithms by system/syndrome. Focus areas will include enteric disease, respiratory disease, septicemia/joints/CNS disease, and metabolic disease. Discussion will focus on step-wise diagnostic methodology, primary rule-outs, capabilities and limitations of diagnostic tools, and gold-standard tests for confirmatory diagnosis. Seminar participants will leave with a take-home reference guide on how to take a clinical presentation and end up with a treatable pathogen.

After a refreshing break, we will reconvene to discuss the next development in oral fluid technology, understanding the use and performance of PRRS ELISA adapted for oral fluids, followed by field experiences from two practitioners who have implemented oral fluid PCR testing in their system/practice. They will share their insights on how oral fluid testing has added value to their practice and diagnostic methods.

Finally, as many practitioners struggle with managing the plethora of diagnostic data that we collect, the session will wrap up with a glance at one unique method of handling diagnostic data.

Seminar #9: Swine Production and Medicine for Veterinary “Students”
Seminar co-chairs: Jeremy Pittman and Angie Supple

The goal of this year’s student pre-conference seminar is to provide information in areas we feel are essential for new and recent graduates based on the experiences of recent graduates. This seminar will supplement the students’ veterinary curriculum, and while focused on swine, the concepts are applicable to all fields of veterinary medicine. The seminar will include topics on development of differential disease lists, interpretation of diagnostic reports and “putting it all together.” A popular component will return: an interactive case study where students will work step-wise through a case in small groups. To end the seminar, we will have an open question and answer session with a panel of recent graduates representing various areas of the industry.

Not just for students! While the session is geared towards students, we strongly feel the information and interaction is applicable to all members of AASV.
