Summary
# Editorial Summary Mineral composition of the hoof wall directly influences structural integrity and resilience to common pathologies, yet breed and sex-based differences in key micronutrient profiles remain poorly characterised in equine practice. Researchers compared hoof tissue samples from 46 horses (22 Polish sport horses and 24 purebred Arabians, split evenly by sex) using atomic absorption spectrometry and the Bardsley-Lancaster method to quantify sulphur, iron, zinc, copper and calcium concentrations and their interrelationships. Arabian horses demonstrated significantly elevated calcium and zinc levels compared with Polish sport horses, whilst the latter showed higher copper content; sulphur showed sex-related variation only in the Polish sport group. Of particular clinical relevance, negative correlations emerged between calcium and zinc in Polish sport horses and between calcium and iron in Arabians—suggesting that elevated mineralisation in one pathway may compromise others, potentially predisposing to specific hoof wall vulnerabilities within each breed type. These findings suggest that nutritional and supplementation strategies should be tailored not only to individual horses but potentially to breed phenotype, as the optimal mineral balance for hoof health may differ between performance types, and practitioners should monitor for antagonistic mineral interactions rather than pursuing uniformly high micronutrient levels across all populations.

Practical Takeaways
- •Breed-specific mineral profiles exist in hoof horn; Arabian and Polish sport horses require different nutritional management strategies to optimize hoof mineral balance
- •Mineral antagonisms (Ca-Zn and Ca-Fe) suggest that simply increasing one mineral may impair absorption or utilization of others; practitioners should consider mineral ratios rather than absolute levels
- •Farriers and nutritionists should account for breed differences when evaluating hoof quality issues and formulating supplementation protocols for hoof health
Key Findings
- •Arabian horses had significantly higher Ca and Zn levels in hoof wall compared to Polish sport horses
- •Polish sport horses had significantly higher Cu content than Arabian horses
- •Significant negative correlation between Ca and Zn in Polish sport horses (p=0.0208)
- •Significant negative correlation between Ca and Fe in Arabian horses (p=0.0118); gender differences in S content observed only in Polish sport horses
