Dr. Vande Pol grew up in central California and received her PhD in animal sciences focusing mainly on pre-weaning piglet mortality. She suggests researching and questioning answers that were previously found because what was true in a genetic line or during a certain time period may no longer be true today. It is necessary to objectively question all stages of pig production. Do you agree?

We all know that it’s important to be proactive and act to prevent big losses in swine production. Dr. Yeske mentions the importance of always reviewing all biosecurity protocols both inside and outside the barn before an outbreak investigation occurs. Do you agree?

As a professor and researcher, Dr. Karriker has been working with swine disease diagnosis and treatment, as well as assessing new intervention strategies for the pig industry. He points out that genes that are resistant against some antibiotics such as Colistin could already exist, but at a low level, since this antibiotic has not been used so widely. However, it is very complex to cite the causes of the introduction of new resistant genes, since many factors are involved. Do you agree?

As a scientist at Smithfield Foods, Dr. DeDecker says that conducting PRRS research is still the biggest challenge that is faced in commercial research because of the dynamics of this disease and the uncertainty regarding an effective response. For scientists, it's about challenging the experimental design, but it poses a much more significant challenge for veterinarians. What other challenges could you mention?

Dr. Ritter, Director of Nutrition and Technical Services at Cargill, explains how to escape high-stakes ingredients by avoiding sourcing from risk areas, and how using strategy hold times can minimize risk when this is not possible. Also, nowadays, it is possible to find ingredients that offer alternative technologies that prevent those viruses in the market, and, when allied with biosecurity measures, we mitigate those risks. Do you agree?

When developing and evaluating new technologies for pig farms, finding the best way to measure their success is crucial, as conventional scientific approaches may not apply. Dr. DeDecker discusses how we, as scientists, can test and implement new technologies. Very interesting, right?

The colder weather this time of the year is not only harder on us, but also harder on our pigs. One issue is that we typically see increased incidences of virus outbreaks on farms such as PRRS and PED. In today’s roundtable episode with Dr. Ritter from Cargill and Dr. Strobel and Dr. Yeske from the Swine Vet Center, they talk about ways we can mitigate the effects of PRRS and PED on our farms and keep it from spreading if we already have it.

𝗠𝗲𝗲𝘁 𝘁𝗵𝗲 𝗴𝘂𝗲𝘀𝘁𝘀: With 30+ years of swine veterinary experience, Dr. Paul Yeske has gained recognition for his work with disease management and elimination. He also has earned two veterinary awards — the Swine Practitioner of the Year in 1998, and was selected to give the Howard Dunne Memorial Lecture in 1996 . Today, Paul is a senior member of the veterinary team at the Swine Vet Center (SVC), which includes 15 veterinarians. He attended Iowa State University where he stayed until he earned his Doctorate of Veterinary Medicine in 1985. His first job was at a large group practice, until he switched to SVC.

Ryan Strobel knew at a pretty young age that he wanted to work with livestock. He credits his interest in the industry with growing up on a hog and crop farm near Pemberton, Minnesota, and having an uncle who is a veterinarian with setting the seed for his future. He raised livestock in 4-H and later judged livestock as an undergraduate at the University of Minnesota. While at the university’s veterinary school, Ryan worked twice at the Swine Vet Center (SVC) — a short summer internship after his first year and an externship in his fourth year. After receiving his Doctorate of Veterinary Medicine in 2017, Ryan worked at another clinic until 2018, when he moved to SVC.

Dr. Matt Ritter works closely with Cargill's nutrition teams, marketing personnel, sales force, support, and staff to deliver best-in-class nutritional solutions and services to customers. He graduated with his B.S. and M.S. in Animal Science from Michigan State University before attending the University of Illinois to receive his Ph.D. in Animal Sciences. He's currently Director, Nutrition and Technical Services at Cargill.

Although we have seen so many changes in sow production over the last few decades, some things remain constant. Given his extensive experience in the swine industry, Fred Kuhr shares his perspective on the elements of swine operations that don't change over time. Among them is the need for quality people to work in the barns. What other topics would you add to that?

The U.S. Department of Health & Human Services defines antibiotic stewardship as the effort to measure and improve how antibiotics are prescribed by clinicians and used by patients. Dr. Karriker brings that discussion into the swine industry and shares his thoughts on how the concept can be applied to our field. Have you heard of this concept?

Dr. Cortus's position as assistant professor and extension engineer is to provide engineering expertise in the area of sustainable animal agriculture systems. As air emission monitoring is very challenging, Dr. Cortus discusses how we can measure that. Interesting, right?
