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 members only)
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: AASV's Got Talent
Seminar chair: Jeff Harker
If you are having a hard time deciding which pre-conference seminar to attend, then this is the one for you. With a wide variety of topics and no proceedings to reference later, this is a “can’t miss” seminar. This year’s practice tip session features many topics you asked for on last year’s survey, as well as several ideas volunteered by leading practitioners. As always, these presentations will be high quality, since these practitioners are in competition for the “tipster of the year” cash award. Also, these busy vets were unburdened with completing a proceedings paper so content can be “hot off the presses”! We hope to see you at the 2017 AASV’s Got Talent seminar.

Fee:
Limit: 20 participants
This seminar will focus specifically on influenza phylogenetics and bioinformatics using web-based tools available for public use. The seminar will be divided into two parts. The first half will provide information regarding the basic fundamentals of phylogenetic trees and sequence analysis tools. In addition, this half of the seminar will focus on sequence applications available in the Influenza Research Database (IRD) and provide updates on additional influenza bioinformatics tools.
The second half of the seminar will feature a two-hour interactive workshop that will guide the veterinarian through interpreting a diagnostic lab report that includes a diagnosis of influenza A virus respiratory disease in swine. The information from the case will be used to extract and manipulate an influenza sequence in the IRD tool with subsequent phylogenetic analysis that includes sequence alignment, homology matrix interpretation and creating dendrograms. Participants will be able to use and understand the basic features of the IRD for influenza A virus in swine and improve their ability to create and interpret phylogenetic information provided through this web-based tool.

Seminar chair: Al Eidson
Co-sponsored by AASV and the National Pork Board
In 2011, AASV and the National Pork Board partnered to train veterinarians as OMS speakers with a goal to help focus pork industry outreach efforts to professional veterinary associations, schools of veterinary medicine and veterinary technical colleges.
To date, the program has 109 OMS-trained veterinarians, who have presented to 29 of 30 schools of veterinary medicine and overall, more than 213 OMS speeches have been scheduled, with an audience reach of 14,117.
This training updates participants on what activists are saying about agriculture today, and will provide attendees with the needed tools and presentations to address those concerns in a science-based, proactive manner. The objective is to equip veterinarians to speak to veterinary medicine students and to professional groups including veterinary associations and dieticians. Unless otherwise indicated, presentations will be made by Al Eidson.
Attendees are encouraged to bring a laptop for note taking.

Seminar #6: Antibiotic-free Pork Production
Seminar chair: John E. Baker
Understanding consumer demands and finding new tools and technologies to manage bacterial diseases challenging the pigs in our care
The development of programs for antibiotic-free pork production is on the rise in our industry. Antibiotics play a vital role in the prevention and treatment of many bacterial agents that threaten the lives, health, and welfare of pigs. Antibiotics also improve the safety and wholesomeness of pork products provided to the American consumer.
However, increasing numbers of consumers are convinced that meat produced without the use of antibiotics is safer, more wholesome, and more socially responsible than conventionally raised meat. Although this is not supported by scientific research, the old adage that “the consumer is always right” has led to production protocols that seek to capture the added value of these consumer demands.
The removal of antibiotics as a tool is a significant loss in managing bacterial pathogens. This has left veterinarians scrambling to find new tools and technologies to manage these diseases and continue to provide for the health and welfare of the animals in their care.
This AASV pre-conference seminar has been developed to better understand consumer demands and provide new technologies to manage bacterial agents in the antibiotic-free production systems.

Seminar #7: ESF from A to Z
Seminar co-chairs: Tom Parsons and Meghann Pierdon
A variety of new sow housing and feeding systems are being implemented to address growing market demand for alternatives to the gestation stall. Electronic sow feeding (ESF) remains one of the few options, if not the only one, that offers individual animal nutrition as well as additional upside potential for innovation. Alas, it is also likely the most challenging alternative to implement. Here lies a tremendous opportunity for veterinarians to take a leading role in helping their clients through the transition to ESF and to reap the unique benefits that this technology promises. The goal of this seminar is to improve the veterinarians’ understanding of the fundamentals of ESF including barn design, pig flow, and staffing/personnel requirements. Furthermore, expert opinion on the advantages and challenges of ESF will be provided from the perspective of a production manager, a nutritionist, and a genetic supplier. Case study material will be discussed as well as a roundtable question and answer session held to help ensure that veterinarians are able to provide a competitive advantage for their clients who are transitioning away from the gestation stall.

Seminar chair: Jane Christopher-Hennings
This “One World, One Health, One Passion for Pigs” diagnostics seminar will cover the basics on multiple pathogen diagnostic testing including rotavirus and Mycoplasma, along with emerging diseases which have foreign animal disease implications, such as Seneca Valley virus. For example, in the case of Seneca Valley virus, it will be important to obtain the perspective from a state veterinarian on how industry, veterinarians, and state animal health officials can work together on controlling these emerging and foreign animal diseases as they emerge. DNA sequencing and bioinformatics will be discussed in the context of antibiotic sensitivity testing and pathogen tracking. Finally, the ability to put information together from a case perspective in a diagnostic laboratory is dependent on optimum samples, choosing the best tests, accurate testing, and excellent communication. “Case scenarios” will be presented to get the most out of the laboratory. A panel discussion will conclude the session to answer your questions regarding any of these topics or “diagnostics” in general. We intend this session to be full of “news you can use.”

Seminar #11: Feed: Commanding New Focus
Seminar chair: Dwain Guggenbiller
Constituting the largest expense in producing pork, feed is often overlooked in the scale of importance. However, history has indicated that we must be vigilant about what unwanted disease-causing agents may be in our feed. Also, whether it be due to consumer preferences, legislative guidances, or demand fulfillment, producing pork with antibiotics used judiciously – or even without antibiotics at all – will be an evolutionary change for United States producers and the swine veterinary community. With this as a background, this seminar will look at feed biosecurity, upcoming legislation on how we keep our food safe, products that are alternatives to antibiotics, and what we know about life inside the digestive system.
