Lameness is one of the most prevalent welfare problems in dairy cattle, and regular foot trimming is a key preventive and therapeutic tool.
Lameness causes chronic pain that undermines the welfare of a significant fraction of the dairy herd at any one time. Affected cows shift weight to reduce pressure on painful feet, altering gait and posture in ways that themselves cause secondary musculoskeletal strain. Pain suppresses appetite, social interaction, and reproductive function — creating a cascade of welfare impacts beyond the primary lesion. Preventive foot trimming by trained hoof trimmers, combined with locomotion monitoring by farm staff, is the single most impactful lameness welfare intervention available. Farms that combine regular trimming with rubber flooring, prompt treatment protocols, and mobility scoring achieve lameness prevalence well below 5% — demonstrating that low lameness is achievable, not merely aspirational.
