The focus of this seminar is to provide attendees with practical information on the boar stud industry. It will address the ever-continuing issues of bacterial contamination and lameness along with a variety of other important topics.
The seminar will begin with an overview of semen traceability and where we are as an industry. In the spirit of the theme “Be the Pig’s Champion,” we will expand our knowledge and learn about boar studs in the show pig industry. Next, a series of presentations on semen contamination will include a current overview of reprotoxins and spermatotoxins, a field case of bacterial contamination, and a closer look at Ralstonia pickettii in a boar stud setting, followed by a panel discussion.
After the refreshment break, attendees will receive tips from diagnosticians on sampling boars and performing post-mortem lameness exams, followed by advice on how to improve animal welfare and staff safety when building or updating boar stud facilities. The seminar will conclude with presentations on managing boar lameness and feeding.
The information presented in this seminar will be valuable not only for practitioners who routinely work with boar studs, but also for those with sow farm clients, as these topics have impacts on downstream production.

ChatPIG
Co-chairs: Brent Sexton and Brandi Burton
Today, it is almost impossible to attend a swine meeting, whether producer- or veterinarian-focused, where someone doesn’t bring up how AI is being used across the industry. They’re not talking about traditional AI (artificial insemination) used in everyday swine operations. They’re talking about artificial intelligence!
This seminar will focus on what AI is, its capabilities, how we are or can use it today in everyday operations, and where it is going for future use. The speakers in this seminar will cover a wide variety of topics and help those who attend understand how they can take this information back home and implement it immediately. While we’re in the heart of Silicon Valley and the tech capital of the world, there is no better time to learn about AI and technology’s role in the swine industry!

Seminar #6: Biosecurity
Biosecurity
Co-chairs: Derald Holtkamp and Kate Dion
This seminar brings new perspectives on how to help producers improve biosecurity in the pork industry. The last four decades have witnessed a revolution in the way pigs are produced that has increased the consequences of outbreaks and created extraordinary challenges for preventing the introduction of pathogens into herds. With African swine fever virus knocking on our door, the importance of improving biosecurity has never been higher. Despite a large investment in time and money in biosecurity, the pork industry still struggles to reduce the frequency of outbreaks in sow herds and the lateral introduction of endemic pathogens into groups of growing pigs. The aim of this seminar is to introduce alternative perspectives and novel approaches for veterinarians to help producers improve biosecurity and make sustainable progress.

Specifically, we will review the pre-work visit process, executing visit observations, developing and negotiating health action plans, and follow-up communication strategies to ensure your visits create value for all stakeholders. Given that teaching is a critical component to many farm visits, we’ll explore the most effective teaching tools for farm employees. The Adult Learning Model and Situational Leadership will be explored with specific strategies covered to ensure that your training is effective and results in optimal health management implemented by farm employees following your visit.
