Seminar co-chairs: Chris Rademacher and Dale Polson
Fee: $95

The Internet of Things (IoT) has been growing exponentially, and “SMART” everything is taking over the world – SMART sensors, devices, homes, businesses, cities, ecosystems.Precision Agriculture, the IoT of crop production, has been established for years now and continues to grow rapidly.Precision Livestock Farming (PLF), the IoT of livestock production is just recently gaining momentum, even though it has existed for quite a number of years (predominantly in Europe, and primarily in dairy).This preconference session will explore the emerging technologies and ecosystems that are developing and gaining use in livestock production in general with a focus on what is coming, available and in use across pig/pork production. To remain relevant and thrive in the brave new world of IoT in livestock production, veterinarians must become competent and proficient in the use of these emerging technologies and learn how to function effectively within the PLF ecosystems where these technologies are integrated.

Seminar #4: Conducting Effective Outbreak Investigations: Learning from our mistakes
Seminar chair: Derald Holtkamp
Fee: $95

Want to help producers learn from outbreaks of PRRS, PED, and other diseases? This seminar will introduce participants to concepts and resources to efficiently and comprehensively conduct epidemiological investigations of outbreaks in swine herds for the purpose of identifying where the herd was most vulnerable to the introduction of the pathogen. Even when a “smoking gun” is not found, the knowledge gained from such investigations may be used to influence decisions on where to spend resources to improve biosecurity.

Participants will be introduced to resources (forms, examples, training videos, etc) available online through the Swine Health Information Center’s (SHIC) Rapid Response Program (RRP) for conducting epidemiological investigations of outbreaks. The seminar will provide participants in SHICS’s RRP with additional training to prepare them to conduct investigations in response to a new transboundary or emerging swine disease in the US. All participants will learn how to use the program materials in their practice or production system to conduct more effective epidemiological investigations of endemic disease (e.g. PRRS or PED) outbreaks.

Seminar chair: Al Eidson
*Time: 12:00 - 5:15 PM (note the early starting time!)

Fee: No charge
Eligibility: US AASV member veterinarians only

Co-sponsored by AASV and the National Pork Board

Since 2011, AASV and the National Pork Board have 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 132 OMS-trained veterinarians, who have presented to 29 of 30 schools of veterinary medicine. Overall, more than 296 OMS speeches have been scheduled, with an audience reach of 12,728.

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. Trainees will receive media training and assistance on how to handle hostile audiences. The objective is to equip veterinarians to speak to veterinary 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.

Leadership styles training for developing more effective and productive working relationships
Fee: (no free vet student registration)
Limit: 35 attendees (pre-registration by February 15 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. She is currently serving as the Talent Development Manager for Smithfield Foods and is responsible for employee and organizational development through programs that enhance and advance key organizational objectives.

This seminar is designed to supplement veterinary students’ education on topics of swine medicine. This year’s topics on antibiotics were requested by several of last year’s attendees, and are a common area of “opportunity” for new and future veterinarians. The goal of the seminar will be to review the basics of pharmacology and antibiotic selection as they relate to swine medicine in the field. In addition, we will review the current requirements of AMDUCA, veterinary prescriptions, and Veterinary Feed Directives, as well as the veterinarian’s role and responsibility in antibiotic stewardship. Following these reviews, students will participate in several interactive cases where they will use their new knowledge to make antibiotic decisions for some real-world cases.
