In this episode of The Poultry Podcast Show, Dr. Jennifer Ronholm, Associate Professor at McGill University and Canada Research Chair in Agricultural Microbiology, explains how poultry gut microbiomes shape health and performance. She breaks down antibiotic use realities, resistance risks, and practical paths forward with probiotics, fiber, and management. Learn what “healthy” really means in a chicken gut and why multi-strain solutions matter. Listen now on all major platforms.

“Antibiotic exposure can disrupt gut community structure, reduce protective functions, and increase the likelihood that resistant organisms and resistance genes spread beyond farm boundaries.”
