Summary
# Editorial Summary Pregnant and early-lactation heifers experience markedly different patterns of hoof disease when first housed, with lactating animals presenting substantially more severe lesions even before housing commenced. Researchers tracked 20 heifers (10 pregnant, 10 early-lactation) under identical cubicle conditions over six weeks, conducting weekly lameness assessments and detailed hoof examinations including photographic analysis and digital lesion mapping to measure both severity and location. The lactating group exhibited significantly greater total lesion scores at baseline, and critically, the severity of linear lesions in these animals correlated with behavioural changes—reduced lying time, increased cubicle standing, and more restless lying behaviour. These findings suggest the metabolic and physiological demands of early lactation compromise hoof integrity independently of housing factors, whilst simultaneously increasing pain-related behavioural alterations that themselves may exacerbate lesion development through prolonged standing. For practitioners, this indicates that early-lactation cows warrant heightened vigilance for hoof disease and potential pain-driven behavioural signs, with intervention protocols potentially benefiting from consideration of metabolic support and pain management alongside conventional farriery.

Practical Takeaways
- •Monitor lactating heifers closely for hoof lesions at housing, as they show increased lesion severity compared to pregnant animals
- •Observe lying behaviour patterns as an early indicator of hoof pain—reduced lying and increased cubicle standing may signal developing linear lesions requiring intervention
- •Housing design and management should prioritize comfort for early lactation animals, as metabolic demands and hoof lesion severity are higher during this production stage
Key Findings
- •Early lactation heifers had greater total lesion scores before housing compared to pregnant heifers
- •Severe linear lesions in lactating heifers were associated with reduced lying behaviour and increased standing in cubicles
- •More severe lesions in lactating heifers corresponded with less idling and more disturbed lying behaviour
- •Hoof lesion development and behavioural changes were evident within 2 months of housing
