Respiratory disease detection turns technical

New technology could help the cattle industry better manage bovine respiratory disease, a veterinarian told the Saskatchewan Beef Industry Conference.

Dr. Emily Snyder, assistant professor at the Western College of Veterinary Medicine with a research focus on BRD, said current treatment methods have led to concerns about antimicrobial resistance.

Widespread treatment of all animals entering a feedlot, which is the population most at risk of developing BRD, with an antimicrobial has been shown to work but the practice could also result in selection of bacterial strains that are resistant.

“We’re thinking that if we can identify those animals that are particularly high-risk and just give those some metaphylactic treatment and then those that are at lower risk, not treating those, we might be able to reduce our drug use in that way,” Snyder said.

That’s where chute-side diagnostics come into play.

One tool in development is QScout BLD, a test that includes a blood sample on arrival at the feedlot with results within 30 seconds. By assessing the white blood cells in the sample, the test would allow producers to make animal health decisions.

Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
