Dairy Cow Longevity and Welfare | Animal Welfare Hub

Average dairy cow lifespan in intensive systems is 4 to 6 years, far below their natural 20-year lifespan. Improving longevity is simultaneously a welfare goal and an economic and environmental one.

Key Facts

Average productive life of a US dairy cow is approximately 2.5 lactations before culling
Lameness, mastitis, and reproductive failure are the primary reasons for early culling
Cows that calve for the first time later have longer productive lives on average
High-welfare systems in Switzerland and Scandinavia achieve significantly longer productive lifespans
Each additional year of productive life reduces the carbon footprint per unit of milk produced

Welfare Considerations

Short dairy cow lifespan is both a welfare indicator and a welfare cause. Cows culled after 2 to 3 lactations for lameness and mastitis have experienced those conditions as chronic welfare harms before culling. Improving longevity requires addressing the root causes of early culling: reducing lameness through housing and hoof care, reducing mastitis through hygiene and cow management, and supporting reproductive health. Longer-lived cows represent better welfare across their lives.
