Lameness affects approximately 25% of dairy cows at any given time in intensive systems and causes significant chronic pain. Systematic hoof care programs and housing improvements deliver the greatest welfare gains.
Dairy cow lameness represents arguably the most significant welfare problem in mainstream animal agriculture. The scale — millions of cows worldwide experiencing chronic pain — combined with the chronic nature of the condition creates an enormous burden of suffering that is frequently normalized within the industry. Lame cows show reduced feeding time, reduced lying time, altered social behavior, and all the classic signs of chronic pain. The economic cost of lameness (reduced milk yield, reproductive failure, early culling) creates a business case for welfare improvement, but adoption of even cost-effective interventions remains incomplete. Lameness scoring, hoof care programs, and housing improvement represent the highest-impact available welfare interventions in dairy.
