Lameness affects 20-25% of dairy cows and is the second most economically significant welfare problem after mastitis; prevention through hoof care and surface management is highly effective.
Lame dairy cows experience chronic pain that is frequently undertreated in commercial settings. Studies show that as few as 10% of lame cows receive veterinary treatment, with farmers often accepting a degree of lameness as normal. The welfare significance of lameness - chronic pain during every step for months at a time - is enormous and the preventive tools including rubber flooring, hoof trimming programs, and locomotion scoring are well established.
