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

PRRS Risk Assessment Training for the Breeding Herd
Coordinator: Derald Holtkamp
Limit: 20 participants (AASV membership required)
Fee: No charge

7:30 AM – 12:00 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 has improved access, ease of use, and the ability to view benchmarking reports immediately after submitting an assessment.

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: Diagnostics
Seminar Chair: Simone Oliveira
Moderator: Jeff Zimmerman
Fee: $90
1:00 - 5:00 PM

The objective of this year’s diagnostics seminar is to update swine veterinarians on the latest news in development, validation, and field applications of NEW diagnostic tests. Key diagnosticians from Iowa State University, Minnesota, and South Dakota diagnostic laboratories will share the newest technologies available to address the most recent challenges faced by today’s swine industry. Three field veterinarians who have applied such innovative technologies will join the diagnosticians to share their experiences with these new methods and tests under field conditions. This section will address evidence-based medicine from two important perspectives: laboratory and field.

Seminar #2: Alternative (Opportunity?) Feed Ingredients in Swine Diets
Seminar Chair: Harold Tilstra
Fee: $90
1:00 - 5:00 PM

The pork industry has become quite skillful at using dried distillers grains with solubles in pig diets. That experience may have increased awareness of other ingredient possibilities. There are ingredients from other grain-processing industries as well as locally available ingredients that may provide individual opportunity feeding possibilities. Also, the bio-fuels industry is trending towards further bio-refinements that change the nutritional profiles of the remaining feed ingredients. There are ingredient possibilities that literally reach from “a” to “z”: alfalfa meal to zein protein. Even though the probability of a specific ingredient’s use may vary, it is very likely that swine veterinarians will encounter production situations and/or producer questions relating to the use of some type of alternative ingredient. This seminar will provide information about maximizing the benefits and avoiding the pitfalls of using alternative ingredients in swine diets.

1:00        What does a swine veterinarian “need” to know about alternative ingredients?
                Joel DeRouchey

1:45        Do I have to compromise performance when I feed alternative ingredients?

Seminar #3: “We the Jury…” – Seeking, Interpreting, and Using the Evidence of Trial Data
Seminar Chair: Spencer Wayne
Fee: $90
1:00 - 5:00 PM

  Making decisions by gut feelings? Want your decisions to be guided more by evidence and less by opinions? The seminar will start out by refreshing your understanding of what numbers mean (interpreting P-values, confidence intervals, and power-analysis). After re-establishing your footing in stats, we move into field trial design from the perspectives of both a field practitioner deriving knowledge for clients’ needs and a system research director discussing how to arrive at a verdict on current pork-production practices and products through the use of commercial research barns. Discussion will be focused on commercial trial evaluations with an understanding of setting up objectives, treatment design, randomization activities, data interpretation and how to work through unexpected events during a trial. We’ll utilize an interactive approach, working through 2 or 3 examples of setting up a trial barn based on objectives, study design, and required methodology. Examples will include blocking trials based on weaning events as well as in litter based trials. Finally, we’ll get an inside view of how commercial product research is designed, executed, evaluated, presented, and otherwise used.      Here we’ll outline the span of clinical studies from discovery to the development process for biologics and pharmaceuticals; with a discussion of USDA/FDA requirements for licensure, the statistical methods implemented, etc. Seminar participants will leave with a deepened appreciation and understanding of how evidential data can and should guide a decision-making process.

Seminar #4: Communicating Using Social Media
Seminar Chair: Lisa Tokach
Fee: $90
1:00 - 5:00 PM

If your answer is “yes,” come join Brenda Tassava, a certified veterinary practice manager and social media enthusiast to get started.

Speaker: Brenda Tassava

1:00        Using social media appropriately

Social media calls for a whole new approach to media and the Internet, not just for you and your practice but also for your staff. This means creating a policy that makes sense, as well as training your staff to use social media appropriately. This session will cover example policies, best practices, as well as a formula for training your team in a staff meeting setting. Have a staff that embraces social media concepts? I’ll introduce you to a tool that enhances your internal team communications, using a social media format

2:45        BREAK

3:15        Social media marketing for your veterinary practice

Social media marketing is a necessity in today’s world. This session will cover the ways the world has changed very quickly in the past 5 years, which has led to a need to market veterinary practices differently. Social media isn’t just about Twitter and Facebook. Your practice needs a strategy, but first you need to fully understand what social media is, and best practices for its use, then we’ll walk through building your practice’s social media strategy.
