Program Chair: Dr. Ron Brodersen


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.

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.

Seminar #1: Beyond Our Oath: Primum non nocere and other excellent tips, tricks and shortcuts
Seminar chair: John Waddell

Back by popular demand, the practice tips pre-conference seminar will again provide even more great “tips, tricks and shortcuts” to take home and utilize immediately in your practice and business. This year will feature tips from veteran practitioners and “young guns” alike for a great mix of experience and unbridled enthusiasm. As in year’s past, no proceedings will accompany these tips so you have to be “in the seats” to get the latest as these stalwarts of our profession compete to be the “top tipster” for cash and prizes.

Seminar #2: Coronavirus Diagnostics and Surveillance
Seminar chair: Alex Ramirez

Since the introduction of PED in the US in 2013, porcine coronaviruses have become a clinical and diagnostic reality. The swine industry and profession have had a lot to learn and accomplish in just a few months. With so many unknowns and the development of many diagnostic tools, swine veterinarians are cautiously learning how to better use and interpret these tools to make the right decisions which will impact the health and wellbeing of millions of pigs. This pre-conference seminar will spotlight porcine epidemic diarrhea (PED), while referencing porcine delta coronavirus where applicable. The ultimate goal of this seminar is to enhance our current understanding of applicability and interpretation of diagnostic assays.

Seminar chair: Nathan Winkelman

Benchmarking record systems show us that the top 10th percentile of US swine farms are at 29 pigs weaned per sow per year, and the very best are at 34 pw/s/yr!

The objective of this session is for our panel of experts to evaluate the genetic, management, and nutrition technologies needed to achieve this level of production, and try to understand why more herds aren’t reaching their potential. The last two speakers will examine the reproduction and financial records, employee philosophy, and details for success of one of the best sow farms in existence today.

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

The student pre-conference seminar has been set up to provide supplementary and useful information that students may not receive in their veterinary curriculum. The goal is to provide this information through the experience of recent graduates who remember what it was like to be a student. This year, we will return to a topic that is consistently requested and in which many student feel deficient upon graduating: medication. In addition, the ever-popular interactive case will return in this session. To close the session, we will have a question-and-answer panel of recent graduates (within 1 year) from a variety of practice types.

Seminar #11: Boar Stud Health, Biosecurity, and Technology
Seminar chair: Joe Fent

Our focus is two-fold: first, to address the challenge of PEDV specific to boars, and second, to examine the ways boar studs influence reproductive performance. Whether you are responsible for the health of a boar stud, need to know more about the judicious use of CASA systems to better apply motility, morphology, and morphometry parameters at the production level, have an interest in reference lab flow cytometry analysis, or work primarily with sow farms and want to hear a western European perspective on what boar studs can and should be doing to protect and enhance your client’s performance, this is the session for you. Swine practitioners and consultants will leave this seminar with practical information they can apply immediately, and will gain confidence in becoming familiar with topics they are likely to encounter in the near future.
