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.

Video: Genetics vs Genomics in Swine - Dr. Max Rothschild



In this episode of The Swine it Podcast Show Canada, Dr. Max Rothschild, Distinguished Professor at Iowa State University, explains how genetics and genomics have transformed swine production. He explores genomic selection, key gene discoveries, and the role of gene editing in improving disease resistance and productivity. Practical insights on litter size, meat quality, and industry adoption are also discussed. Listen now on all major platforms!

"Genetic improvement in swine production accelerated significantly once molecular tools enabled identification of DNA level variation influencing growth, reproduction, and meat quality across commercial populations."

Meet the guest: Dr. Max Rothschild / max-f-rothschild-b3800312 earned his PhD in Animal Breeding from Cornell University and has spent over four decades at Iowa State University advancing swine genetics and genomics. His research focuses on genetic improvement, disease resistance, and molecular tools for swine production. A leader in pig genome research, his work has shaped modern breeding strategies.
