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.”

Meet the guest: Dr. Jennifer Ronholm is an Associate Professor at McGill University, Canada Research Chair in Agricultural Microbiology, and Director of the One Health Against Pathogens NSERC CREATE. Her work examines poultry microbiomes, pathogen interactions, and practical alternatives to antibiotics, including multi-strain probiotics and fiber strategies to support gut health and performance.
