Seminar chair: Jordan Gebhardt

Co-sponsored by the National Pork Board and USDA FFAR

The “Improving Pig Survivability” project is a 5-year project encompassing research, education, and extension efforts with the goal of reducing overall mortality in the US commercial swine industry. The project is funded by the National Pork Board and the Foundation for Food and Agriculture Research (FFAR) and includes researchers from Iowa State University, Kansas State University, and Purdue University. Research efforts seek to identify factors contributing to swine mortality in commercial production, and to develop strategies and information that can be utilized to reduce mortality and maximize pig survivability.

Seminar #7: Boar Stud Health, Biosecurity, and African Swine Fever Preparedness
Seminar chair: Deanne Hemker

The focus of this preconference seminar is to provide attendees with current information on health challenges, biosecurity procedures, and African swine fever preparedness for boar stud facilities.

The seminar will begin with a discussion on impacts to business continuity from an ASF incursion in the US and how best to limit those. Attendees will be presented novel research on ASF infection dynamics in a boar stud and subsequent semen transmission. The seminar will transition into biosecurity, with practitioners from various sectors of the industry providing specific examples of biosecurity protocols utilized for supply entry, boar entry, and semen delivery. This will be followed by a discussion on PRRSV breaks in boar stud facilities and lessons learned from conducting outbreak investigations. The seminar will conclude with a discussion on semen quality analysis focused on compensable versus non-compensable semen traits.

The information covered in this seminar will be valuable for practitioners who work routinely with boar studs, but also for practitioners with sow farm clients, as these topics have impacts on downstream production.

Seminar #10: Swine Medicine for Students
Seminar co-chairs: Jeremy Pittman and Angela Supple

This seminar is designed to supplement the education of students and recent graduates with topics specific to swine medicine, delivered in a way to provide key learning objectives and “take homes.” Topics focus on areas to which students and recent grads don’t usually receive sufficient exposure.

This year, based on feedback from previous sessions, we will focus on 1) the input costs to raise a pig through weaning, nursery, and market, and 2) a basic understanding and evaluation of the key metrics to evaluate on sow farm records. We will conclude the session with interactive cases, where attendees will use their new skills to evaluate some “real world” sow records and determine some potential differentials for the “problem.”

MONDAY, MARCH 6

WAKE UP WITH USDA
Dr. Jack Shere

How do we know where all our pigs went without animal identification and an effective traceability system? Is our current traceability system a fairy tale? We have invited Dr. Jack Shere, USDA-APHIS Associate Administrator in charge of emergency planning and response, to attend the AASV Annual Meeting in Colorado. Join Dr. Shere during his special Q&A session, "Wake up with USDA," Monday morning, March 6, 6:30 - 7:30 AM in Cottonwood 6-7. Please plan to attend this unique opportunity to learn more about traceability and the veterinarian’s role. Get your questions answered and express your concerns during this late-breaking addition to the Annual Meeting.
