Lameness affects an estimated 20-30% of UK dairy cows at any time and represents one of the most significant animal welfare problems in agriculture.
Lame cows experience chronic pain that affects their ability to move, feed, drink, and interact normally. Pain-induced stress suppresses immune function and fertility. Many cows tolerate lameness stoically, masking the severity of their condition and delaying treatment. The cumulative welfare burden of widespread lameness across the national dairy herd is enormous.
