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: Dr. 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 capable of accessing the Internet via wireless connection using one of the following web browsers: Mozilla Firefox, Google Chrome, or Internet Explorer.

The very popular practice tips pre-conference seminar is back again this year with even more information for you to utilize in your practice. Once again, this idea-sharing session will feature veterinarians competing for cash and the top spot for the practice tip that will impact our industry the most according to our expert judges. In the past, this very popular session has delivered an abundance of ideas to drive your practice to the next level. Be sure to attend to get the latest information, as there are no proceedings papers!

Seminar #2: Grow-Finish Biosecurity: Reality or Oxymoron?
Seminar chair: Paul Yeske

With the arrival of PEDv to the industry, many farms and systems are re-evaluating their biosecurity programs to make sure they are effective. One of the biggest challenges is grow-finish, which historically has not been very strict. Truck washes and trucking are also areas that have not received much focus. The panel will give insight into their programs, how they set them up, and what to audit.

Seminar #3: Data Management
Seminar chair: Alex Ramirez

The complexity of today’s swine industry necessitates that practitioners have the ability to summarize data in an easy and meaningful way. Data sets are becoming larger and more complex, making it difficult to have a single report that meets everyone’s needs. The purpose of this workshop is to introduce practitioners to the future of data management and to provide hands-on training on how to organize and manipulate data using Microsoft Excel PivotTable features. PivotTables are an easy and powerful tool that can be used in everyday practice. This seminar will also provide practice tips from three different perspectives while providing insight into current and practical uses of data. There will also be a presentation on how one production system is using sequencing information from databases to make better health decisions.

Participants will need their own laptop computer with Microsoft Excel installed to take advantage of the hands-on section of the seminar. The hands-on portion will last 1 hour. Although participants can still learn simply by observing the activity, hands-on experience will maximize the learning and retention of this exercise.

Seminar #8: Effective Communication
Seminar chair: Ginger Pelger

Have you ever attended a boring meeting or workshop? Have you pressented to a group of people only to find that several attendees have fallen asleep in the back of the room? Do you feel like you are saying the very same thing at every farm visit, only to have your recommendations ignored? If any of these apply, you need to attend this seminar! By the end of the morning, you will know how to create and deliver engaging presenations or discussions to groups of 1-2 people up to 200! Four I Adult Learning will allow you to adapt your style to the participants and involve them in the communication process.

Seminar chair: Joseph Rudolphi

Difficult practitioner cases bring out the best of the coordination with the diagnostic laboratories. This seminar will demonstrate how the practitioners, who have experienced difficult cases or hard-to-interpret diagnostic information, and the diagnosticians, who have been challenged to apply their expertise, can come together into a cohesive unit to meld together science and production to solve the issues. Drs. Darin Madson, Richard Hesse, and Kurt Rossow will be challenged to comment on the diagnostic methods used in the cases, and to answer questions from all attendees as they may pertain to specific diagnostic methods. Attendees should be prepared to challenge speakers and panel members with diagnostic questions.

Seminar #10: Swine Medicine for Students
Seminar co-chairs: Angie Supple and Jeremy Pittman

This seminar has the goal of providing students with supplementary information for their course curricula at school. This year we will provide information on the economics of raising pigs, an important aspect to consider when providing veteriary care for a farm or system. We will also provide a series of short and concise case studies by recent graduates of common and not-so-common problems, highlighting the thought process of a case work-up. We will end with a popular interactive case presentation where students will work in groups to think through a real-life case example.

As always, recent graduates and life-long students are encouraged to participate.
