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

Additional fees apply; you must be registered for the regular meeting sessions in order to register for seminars.
1:00* - 5:20 PM (*except Seminar #5)

Seminar #1: AASV's Got Talent
Seminar chair: Jeff Harker
Fee: $80

This season of AASV’s Got Talent promises to be one of the best yet. Nearly all of the participants' names were mentioned in last year’s survey, and from “hands on” to “sociology,” we are sure you will find an interesting presentation. The quality should be excellent as these practitioners are competing for a cash award and recognition as “Most Talented Tipster.” This session should be full of energy as most of the presenters are relatively early in their careers. There are no proceedings papers for this session, so you will need to attend to garner the most benefit. Global Knowledge will be attained from this session’s individual contributors, so don’t miss out!

Seminar #2: Veterinary Practice Succession
Seminar chair: Chase Stahl
Fee: $95

This seminar will focus on processes and principals involved in the succession of a veterinary practice. Three speakers will be lending their expertise and experiences on this topic. The session will focus on providing veterinarians with insight into transition management, practice valuation, and practice financing. Veterinarians interested in purchasing or becoming a partner will be provided with an understanding of practice valuations, cash flow generation, and steps involved in securing financing. Established veterinarians considering a change such as retirement, part time employment, or adding an associate will be provided with recommendations and suggestions developed from prior, successful business transitions.

Al Bennett, Principle Lending Consultant and Certified Financial Planner at Compeer Financial, will begin the seminar describing his experiences helping clients with their succession planning. He will provide insight into several key components of transitional planning including: maintaining communication, sustaining core values, and understanding and managing tax implications. In addition, Al’s discussion will describe his work helping clients design and implement unique and complex transition plans that mature over several years.

Dr. Tom Burkgren, AASV Executive Director, will provide his experience in valuing veterinary practices. Tom has used his MBA degree for many clients, helping both “buying” and “selling” veterinarians establish a true practice value. Tom’s presentation will focus on the principles he uses when preparing practice valuations.

Dr. Jessica Trichel, Educational Outreach at Live Oak Bank, will provide a unique view on understanding the processes involved with securing financing. Jessica, a recent veterinary graduate, routinely works with young veterinarians to provide a basic understanding of business financials. Her talk will reference several case examples focusing on young veterinarians developing business plans that facilitated practice purchase. Her presentation will be generated from a banker’s perspective.

Speakers will answer questions from the attendees during the panel discussion that concludes the seminar. All speakers are very interested and eager to tackle the audience’s questions.

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 121 OMS-trained veterinarians, who have presented to 29 of 30 schools of veterinary medicine. Overall, more than 284 OMS speeches have been scheduled, with an audience reach of 15,261.

This training includes updates 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 professional groups including veterinary associations and nutrition professionals. Support has been provided by the National Pork Board and the Pork Checkoff.

Attendees are encouraged to bring a laptop for note taking. A box lunch will be provided.

Unless otherwise indicated, presentations will be made by Al Eidson.

Seminar #6: Antibiotic Alternatives
Seminar chair: Nathan Winkelman
Fee: $95

There is a potential for lower antibiotic use due to recent increased industry regulation. There is also a potential economic advantage for antibiotic-free niche markets. This pre-conference seminar will address the risks, challenges, and potential rewards of reduced antibiotic use in today’s market. We will attempt to determine if there are cost-effective alternatives to antibiotics and which pig-flow systems may have the most potential for success.

Our distinguished panel will address:
* Animal welfare dos and don’ts before attempting antibiotic-free pig flows
* A 16-year review of alternative growth promotants in peer-reviewed, original swine research trials
* How to design and evaluate these trials to sort out “good” and “not so good” science so that we can statistically analyze, interpret, and compare different experiments as a basis for management decisions
* A summary of nutraceutical (egg antibody, zinc, and essential oils) trials in the face of a Lawsonia intracellularis disease challenge
* Important feed or water additives for nursery pigs. Are they cost-effective with or without antibiotics?
* Experiences with NAE (No Antibiotics Ever) in a large system: Challenges and opportunities with disease control, performance, and mortality

Leadership styles training for developing more effective and productive working relationships
Fee: $135 (no free vet student registration)
Limit: 35 attendees (pre-registration by February 9 REQUIRED)

Have you ever heard a colleague say, “The pigs are easy; people are the challenge”? Maybe you’ve even made this statement! Do you ever wonder why connecting with some people is more difficult for you than with others? Perhaps you’ve found some clients, colleagues, employees or supervisors easier to motivate and influence than others. If so, then join your AASV peers for the “Leading People” seminar.

This seminar will focus on enhancing the leadership and communication styles of participants based on the DiSC model. Participants will be provided access to complete an individualized DiSC assessment prior to the seminar. The results will be revealed during the interactive seminar, and participants will learn strategies to create more effective and productive working relationships by enhancing their quality of communication and leadership.

Leadership coach: Amy Grinley

Amy Grinley is a Psychology graduate of Central College (Pella, Iowa) with post-graduate Industrial Relations training from Iowa State University. She has more than 20 years’ experience in training and development with companies such as MBS, Inc., Coach House Gifts (Hallmark), and Smithfield Hog Production.

Seminar co-chairs: Marie Culhane and Dale Polson
Fee: $95

The synthesis of Diagnostics, Devices, Digital platforms, and Data analytics

This seminar contains an overview of the current and fast-coming “terrain” in food animal agriculture (e.g., precision livestock farming, IoT, big data, AI, machine learning, cloud computing, cyber-physical systems), as well as more specific topics related to what’s currently available and imminent in each of the “4 D’s”:

*Diagnostics (characterizing the microbiome, meta-genomics, nano-diagnostics, point-of-care diagnostics
*Devices (PLF-based detection and monitoring sensor systems, smart-dosing systems, etc.
*Digital (apps, cloud, web)
*Data (AI, machine learning, ad infinitum)

The seminar objectives:

1) Describe the coming wave of technology that will transform how health and production are managed on farms, in systems, across the country, and throughout the world
