Lameness affects approximately 25% of dairy cows in intensive systems at any given time, making it one of the most prevalent and painful welfare problems in animal agriculture. Understanding its causes and prevention is essential for dairy welfare improvement.
Dairy cattle lameness is arguably the most prevalent serious welfare problem in animal agriculture. The fact that 25% or more of dairy cows are lame at any given time, in a sector with an enormous global herd, means the aggregate suffering is staggering. Lameness causes chronic pain that affects every aspect of a cow's life — her ability to reach food and water, compete socially, lie down comfortably, and move freely. Perhaps most troubling is the evidence that farmers often underestimate the prevalence of lameness in their own herds, and that lame cows are not consistently identified and treated. The management and nutritional changes required to reduce lameness are well-established; the barriers are economic incentives that have historically not valued pain reduction sufficiently, and knowledge gaps in routine lameness monitoring.
