Seminar
#6: Biosecurity
Seminar chair: Derald Holtkamp
This seminar offers speakers from several industries, countries, and professions to bring 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.

#7: Much Ado about Flu
Seminar chair: Micah Jansen
Let’s make influenza fun again! Oh, wait – you never thought that was possible?! While trying to wrap your brain around flu can sometimes feel overwhelming, it’s important to remember that there are still things we can do to improve. The focus of this session is to get back to the basics and put a practical spin on everything we know about influenza A virus in swine (IAV-S) today. As a practitioner, you will be able to walk away from this seminar with specific ideas on how you can change the way you approach flu, based on examples from veterinarians who have had success with influenza control and stabilization.
