Discover how Ciaron Maher Racing (CMR) is pushing the boundaries in the Australian thoroughbred racing industry and breaking away from traditional nutrition strategies. In this in-depth conversation, PhD equine nutritionist Dr. Nerida sits down with Katrina Anderson (Sports Science Lead) and Josh Kadlec-Cavanagh (Head of Data and Performance) to reveal the data-driven approach that's challenging decades of traditional feeding practices. The trio discuss:Why feeding less grain (but more digestible grain) leads to better racehorse performanceThe critical role of hindgut microbiome health in racing successHow faecal pH monitoring allows them to fine tune their feeding programThe connection between gut health and chronic issues like foot soreness and tying-upWhy the "footy horses" at CMR have virtually disappearedThe remarkable case of Saint George: how targeted nutrition reversed severe thrush and fungal issues and got him back on the trackUnderstanding the performance slump when transitioning to more digestible feeds; andThe hard reality about gastric ulcers and race day challengesKat, Josh and Nerida also cover fiber fermentation vs. grain-based energy systems, managing the grain-to-bodyweight ratio for optimal performance, microbiome testing and its practical applications, reducing dependency on supplements and medications like omeprazole and the importance of lucerne hay before morning work. With over 400 horses in training, CMR provides unprecedented data insights into what works—and what doesn't—in modern racehorse nutrition. Whether you're a trainer, owner, stable hand, veterinarian, or equine nutritionist, this episode is packed with, science-backed strategies to improve racehorse health, welfare, and performance. If you’d like to read more about the brilliant microbiome study we discuss, see:Wunderlich G, Bull M, McGilchrist N, Zhao C, Ross T, Rose M, Chapman B.
