Summary
# Editorial Summary Van Heel and colleagues followed 24 Warmblood foals over a year to investigate whether conformational features predisposed them to lateralised grazing behaviour and subsequent foot asymmetry. Through systematic behavioural observation, a standardised laterality preference test, and pressure plate analysis at multiple timepoints (3, 15, 27 and 55 weeks of age), the researchers documented that approximately 50% of the cohort developed a consistent preference for protraction of one forelimb during grazing, resulting in measurably uneven loading patterns beneath the feet. Notably, foals with relatively long limbs and small heads showed significantly greater predisposition to this lateralised behaviour—a finding suggesting that conformational traits associated with athleticism and desirable phenotypes in breeding programmes may inadvertently encourage postural compensation during the critical growth phase. The study provides evidence that what appears to be purely behavioural (grazing preference) is substantially influenced by structural anatomy, with direct mechanical consequences for foot development and loading symmetry. For breeding programmes, farriers and veterinarians, this implies that foals exhibiting the identified conformational traits warrant closer monitoring of grazing posture and foot growth asymmetry during the first year of life, potentially enabling early intervention before established asymmetrical loading patterns compromise distal limb development.

Practical Takeaways
- •Monitor foals with long limbs and small heads early for signs of lateralised grazing behaviour and uneven foot development, as conformational prediction may enable early intervention
- •Uneven feet in young horses may originate from behavioural compensation related to conformation rather than purely pathological causes—address both biomechanical and behavioural factors
- •Assessment of foal conformation should include evaluation of grazing laterality preferences to anticipate and potentially prevent asymmetrical hoof wear and loading patterns
Key Findings
- •Approximately 50% of foals developed significant preference to protract the same limb systematically while grazing, resulting in uneven feet
- •Foals with relatively long limbs and small heads were predisposed to develop laterality and foot unevenness
- •Lateralised grazing behaviour resulted in uneven loading patterns under the feet
- •Conformational traits indirectly cause uneven feet development through stimulation of lateralised behaviour
