Horses did not evolve for stalls, separation, transport, or high-pressure routines, yet this is the reality most horses live in today. That mismatch creates chronic stress, and the consequences do not stay hidden. They show up in digestion, behaviour, performance, soundness, and long-term health.
In this episode, Dr Chris Mortensen (Poseidon Animal Health) explains why stress and gut health sit at the centre of so many modern horse problems, and why missing this link keeps people chasing symptoms instead of causes. We unpack what the hindgut actually does, how stress alters digestion, and why the gut microbiome plays such a powerful role in how horses cope with domesticated life. Chris also clearly explains the difference between probiotics, prebiotics, and postbiotics, cutting through common misconceptions that cost horse owners time, money, and progress.
If you care about making better decisions for your horse, this conversation will change how you think about stress, feeding, and what “supporting the horse” really means.
