Dairy cows are typically culled after 3-4 lactations, well short of their natural lifespan. Improving health management and reducing painful conditions extends productive life and dramatically improves welfare.
Premature culling in dairy cattle reflects widespread welfare failures — cows are discarded when the cumulative burden of painful conditions makes continued production uneconomical. Lameness alone affects 20-30% of cows in many herds and is a major source of chronic pain. Mastitis causes acute local and systemic suffering. Improving longevity requires tackling these conditions at root cause: better flooring and cubicle design to reduce lameness, teat management to reduce mastitis risk, and transition cow management to reduce metabolic disease. Longer-lived cows also reduce the replacement heifer burden, with positive sustainability and welfare consequences.
