Replay: Your horse’s hindgut. microbes and their impact on… everything! (Best of 2025)

Podcast # 33

To wrap up 2025, we’re resharing our most popular guest interview from Season 1 — and it’s a favourite for good reason.

In this episode, microbiology expert Dr Belinda Chapman and Dr Nerida take us inside your horse’s hindgut ecosystem.

Together, they look at what the microbiome actually is, why horses rely on microbes far more than we do, and how the balance between the fibre-loving “good guys” and the weedy, greedy starch-fermenters can influence everything from digestion and energy production to health, performance, and behaviour.

Dr Belinda and Dr Nerida also dive into some seriously fascinating concepts (in a very listenable way), including:

• Why horses have a more complex microbiome than humans

• The underappreciated role of anaerobic fungi in fibre breakdown

• What “quorum sensing” is (and why it’s a bit mind-blowing); and

• Why microbial diversity = resilience (and what that means in the real world)
