Lameness is one of the most painful and prevalent welfare problems in dairy cattle, affecting millions of cows worldwide and representing a serious, largely preventable form of suffering.
Lameness is one of the most significant and widespread welfare problems in modern dairy farming. A lame cow experiences ongoing pain with every step, limiting access to feed, water, and social interaction — compounding suffering across multiple welfare domains simultaneously. The scale of the problem is extraordinary: if 25% of dairy cows in the U.S. are lame, that represents millions of animals in chronic pain at any given moment. Most cases are preventable through rubber flooring, appropriate bedding, regular foot trimming, and early treatment protocols. The fact that lameness remains endemic despite being preventable reflects a systemic failure to prioritize animal welfare over production economics. Regular mobility scoring by trained observers is the standard for welfare assessment.
