Canter Therapy – Dr Shelley Appleton & Kathryn Christieson
What if stress is affecting your mare far more deeply than you realise?
In this powerful episode, Dr Chris Mortensen shares research into how stress impacts mares, reproduction, hormones, blood flow, embryo quality, and behaviour.
Shelley and Kat dive into:
- Exercise-induced stress and fertility
- Hormone disruption and cycling
- Gut health and stress
- Laminitis and metabolic issues
- The role of blood flow in reproduction
- Why stressed plants may contribute to metabolic disease
- Practical strategies for mare management
This is an eye-opening conversation about the interconnectedness of stress, physiology, and horse welfare.
Dr Chris Mortensen is an equine nutritionist and researcher with expertise in equine reproduction, stress physiology, gut health, and performance nutrition. He completed his PhD at Texas A&M University researching the impact of stress and exercise on mare fertility and embryo quality, and now works with Poseidon Animal Health focusing on evidence-based equine health and nutrition.
