Summary
# Editorial Summary Natural weaning in horses occurs around 9–10 months of age when foals are allowed to remain with their dams with minimal intervention, yet domestic weaning practices typically separate animals much earlier and artificially, creating a significant welfare concern that has received limited scientific scrutiny. Séverine and colleagues reviewed existing literature on the dam–foal bond in horses before conducting their own observational study of 16 naturally managed mare–foal pairs, documenting the gradual process of weaning as it unfolds without human-imposed separation. Their key finding was striking: foals managed under natural conditions were weaned spontaneously without observable stress responses in either mare or foal, and without the overt rejection behaviours that might be expected during this transition, though individual timing varied primarily according to mare reproductive status. These results challenge current breeding practice and suggest that earlier artificial weaning—widely employed for management convenience—may impose unnecessary physiological and psychological stress that differs fundamentally from the natural process. Equine professionals should consider whether current weaning protocols warrant reassessment, particularly regarding foal age at separation and handling methods, since evidence now demonstrates that horses naturally manage this transition smoothly when given the opportunity to do so.

Practical Takeaways
- •Consider delaying artificial weaning to 9-10 months and using gradual separation methods rather than abrupt isolation, as natural weaning at this age occurs without stress indicators
- •Monitor mare conception status when planning weaning timing, as pregnancy influences natural weaning progression and may reduce behavioral conflict
- •Reassess current domestic weaning protocols that prioritize early separation; evidence suggests later, naturally-timed weaning warrants serious consideration for improved welfare outcomes
Key Findings
- •Natural weaning in 16 mare-foal pairs occurred spontaneously at 9-10 months of age with minimal human intervention
- •Individual variations in natural weaning timing were primarily driven by mare conception rates
- •Natural weaning induced no measurable stress response in either mares or foals and showed no clear rejection behaviors
- •Scientific literature on natural weaning processes in horses is sparse, with limited documentation of individual variations and immediate post-weaning effects on mare-foal relationships
