Fee: $95

Internet-of-Things (IoT) technologies and ecosystems increasingly touch every aspect of our lives.The number of IoT technologies available to us is growing exponentially … virtually everything is becoming cloud-connected and integrated within highly connected digitized ecosystems.The livestock “version” of IoT – Precision Livestock Farming (PLF) – is experiencing explosive growth globally.The number of start-up companies bringing new technology innovations is rapidly increasing.Also, companies who historically have had nothing to do with livestock are adapting technologies used in other industries and markets and bringing them to the farm.This seminar represents a good mix of presentations on a number of new, adapted, and emerging technologies that will change (for the better) how we do business in pig and pork production.

Seminar #4: Conducting Effective Outbreak Investigations: Learning from Our Mistakes, Part II
Seminar chair: Derald Holtkamp
Fee: $95

Want to help producers learn from outbreaks of endemic diseases like PRRS and PED, and become better prepared for transboundary diseases like ASF? 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 herds are most vulnerable to the introduction of pathogens. If you attended last year’s seminar by the same name, you will find it worth attending again, as this year’s seminar is more focused on the application of the concepts. The seminar will offer several examples of approaches and tools, including outbreak investigations, used to prioritize where biosecurity improvements are needed on individual farms and in larger production systems.

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 (eg, PRRS or PED) outbreaks.

Seminar #7: Pigs Are Easy; People Are Hard
Seminar chair: Ross Kiehne
Fee: $95

It often happens that we neglect the people side of swine veterinary medicine. We do a great job with the pigs and a less-than-stellar job with the people. This includes not selling our ideas enough, not showing leadership to get the job done, not recognizing how we communicate to get the best effectiveness, and lastly, not always recognizing the stress in colleagues’ and clients’ lives. This seminar will attempt to help us in each of these areas.

Seminar co-chairs: Jeremy Pittman and Angela Supple
Fee: $95; no charge for vet students or 2018 or 2019 DVM graduates

This session is designed to be a supplement to veterinary students’ education at their respective schools on topics of swine medicine. This year’s topic will focus on diagnostics. A practitioner will explain collecting the proper samples and sample types based on clinical presentation on the farm. Following this, a diagnostician will present what happens to those samples once they are at the lab, the basics of diagnostic tests, and interpretation of the results. Following these reviews, students will participate in several interactive cases where they will use their new knowledge to make diagnostic decisions for some real-world cases.
