Ep. 36 Can You Smell a Breathing Risk? What Hay Hygiene Tells Us About Equine Respiratory Health

In this episode, we explore how simple sensory checks (sight, touch, and smell) can help predict when hay may pose a respiratory risk for horses. We discuss how abnormal odour emerged as a strong indicator of harmful dust levels, how visible impurities relate to microbial contamination, and what this means for practical, low-cost screening tools in everyday stable management.

In this episode, we are joined by Dr Virginie Bouverat and Professor Vinzenz Gerber discussing their paper titled: Sensory Assessment of Hay Samples: Abnormal Odor Predicts Increased Dust Levels and Impurities Suggest Microbiological Contamination

Virginie is a Swiss equine veterinarian and researcher at ISME, focusing on how forage and bedding quality influence horse respiratory health. Vinzenz is a Swiss equine internal medicine specialist at ISME and the University of Bern, known for his work on equine asthma, genetics, and performance physiology.
