Summary
# Editorial Summary Whilst hoof lesions are common in housed dairy goats, baseline data linking specific lesion types to clinical lameness has been lacking, making it difficult for practitioners to establish which findings warrant intervention. Researchers visited four dairy farms to record locomotion scores and conduct simultaneous hoof inspections during routine trimming on two occasions, documenting 3,850 trimming records and scoring over 3,400 gaits across the visits. White line separation emerged as the predominant lesion, affecting 41.5% of goats trimmed, though notably more goats presented with white line lesions than registered as clinically lame (ranging from 17–95.4% depending on farm and visit). Toe lesions differed markedly in character, with granulomas present in 91.5% of toe separations compared to only 10.6% of white line separations, suggesting distinct pathophysiological mechanisms. The substantial variation between farms in both lameness prevalence (6.7–25.5%) and the proportion requiring significant trimming (15.1–33.1%) indicates that hoof health outcomes are highly farm-dependent, prompting practitioners to establish herd-specific baselines rather than relying on standardised thresholds; however, the discordance between visible lesions and observed lameness suggests that trimming decisions should incorporate gait assessment rather than lesion presence alone.

Practical Takeaways
- •Routine foot trimming records and lesion classification provide valuable baseline data for monitoring hoof health and identifying farm-specific problems across herds
- •The high prevalence of white line separation without corresponding lameness suggests many subclinical lesions exist—early detection through regular trimming may prevent progression to clinical disease
- •Toe lesions are more likely to develop granulomas and may warrant different management or intervention strategies compared to white line lesions
Key Findings
- •Hoof lesions were observed in 65.5% of trimmed dairy goats, with white line separation being the most common lesion at 41.5% of goats
- •Lameness prevalence ranged from 6.7% to 25.5% across farms and visits, consistently lower than the proportion of goats with white line lesions (17% to 95.4% relative proportion)
- •Toe lesions were much more likely to have granulomas (91.5%) compared to white line lesions (10.6%), while separations were far more common than granulomas overall
- •Substantial hoof trimming needs varied significantly between farms (15.1-33.1% of herds) and visits, indicating farm-specific management factors
