Lameness is one of the most significant welfare problems in dairy cattle, causing chronic pain affecting millions of cows worldwide and representing a major challenge for the industry.
Lame cows experience constant pain that affects every aspect of their daily lives - difficulty walking to feed and water, inability to compete with herd-mates, reduced ability to lie down and rest comfortably. Pain from conditions like sole ulcers is assessed as equivalent to moderate arthritis. The high prevalence of lameness in dairy systems represents a systemic welfare failure where tens of millions of cows live with preventable chronic pain. Management changes including flooring, hoof care, and lying space have strong evidence for reducing this suffering.
