Lameness is the most painful and economically costly welfare problem in dairy cattle. Systematic prevention and early detection programs can dramatically reduce its prevalence and associated suffering.
Lameness in dairy cattle is a welfare emergency affecting one in four animals at any given time in typical commercial herds — yet it is so normalized that many farmers do not recognize it as the welfare problem it is. A lame cow experiences chronic pain with every step, reducing her willingness to walk to food and water and competing with other cows. The pain is measurable: lame cows show altered gait, spend more time lying, and have elevated stress hormones. Effective lameness prevention and treatment programs — combining hoof trimming, floor quality, lying time adequacy, and early detection through locomotion scoring — can halve lameness prevalence in herds within a year. The welfare benefit for hundreds of thousands of individual cows makes this one of the highest-impact practical welfare interventions in dairy farming.
