Lameness affects approximately 20-25% of dairy cows in intensive systems, causing significant suffering and economic losses. Understanding that welfare and economics align on lameness reduction helps drive industry change.
Lameness causes persistent, significant pain in dairy cows - a fact now well-established by pain sensitivity research and behavioral observation. A lame cow must navigate the farm environment including walking to the milking parlor multiple times daily while in pain. Body condition deterioration, reduced social competition, and impaired reproduction follow. Despite the clear welfare and economic case for lameness prevention, prevalence remains high in many systems because lameness develops gradually and individual cow pain is not always recognized by farmers managing large herds. Systematic locomotion scoring, prompt treatment with pain relief, and addressing underlying risk factors (flooring, nutrition, transition management) constitute the evidence-based welfare approach.
