Lameness affects 20-30% of dairy cows at any given time and is the single most significant welfare issue in the dairy industry.
Dairy cow lameness is the clearest example of a welfare crisis that is also an economic crisis — yet it persists because the pain it causes is invisible to busy farmers focused on production metrics. Lame cows lie down more, eat less, lose body condition, produce less milk, and have poorer reproductive performance. The underlying causes are largely manageable: concrete floor design, cubicle comfort, walkway maintenance, and footbathing programs all reduce incidence substantially. The welfare intervention that makes the greatest difference is early identification through regular mobility scoring and prompt treatment. A lame cow treated on day 1 recovers in 1-2 weeks; a cow treated on day 30 takes 2-3 months.
