Modern dairy cows have been selectively bred to produce milk volumes so far beyond their evolutionary design that metabolic disease, lameness, and reproductive failure are now endemic in dairy production.
Dairy cow welfare represents a fundamental tension between productivity and health that cannot be resolved without systemic change. The metabolic demands of high milk production create chronic illness - laminitis, ketosis, mastitis - as baseline conditions rather than exceptional occurrences. Every element of the production system - breeding for extreme milk yield, separation of calves, truncated lifespans - imposes welfare costs. Higher-welfare dairy systems with lower stocking densities, outdoor access, and lower-production breeding lines exist but represent a small minority of production.
