Dairy Cow Longevity and Welfare | Animal Welfare Hub

The productive lifespan of dairy cows has declined sharply in intensive systems, with most cows culled well before their natural life expectancy, raising significant welfare concerns.

Key Facts

The natural lifespan of cattle is 15-20 years but most dairy cows in intensive systems are culled at 3-5 years of age
Lameness is the most common reason for early culling, affecting an estimated 20-40% of cows in intensive herds
Mastitis (udder infection) is another leading cause of early culling, with economic pressure driving premature slaughter
Higher-welfare systems with lower milk production per cow tend to have greater longevity
Repeat breeding failures and declining body condition associated with high milk yields drive early culling
Grass-based and low-input dairy systems can achieve cow longevity of 6-8 productive years

Welfare Considerations

Short productive lives in dairy cows represent both a welfare and an ethical concern. Cows that are culled at 3-4 years of age after only 2-3 lactations have often suffered significant health challenges - lameness, mastitis, reproductive disorders - that reduced their welfare and economic productivity. Improving longevity requires addressing the root causes: breeding for health over production, reducing lameness through better flooring and hoof care, and managing transition periods to prevent metabolic disease. Higher cow longevity is associated with better welfare and lower environmental impact per litre of milk produced.

What You Can Do

Choose dairy products from farms certified for higher animal welfare standards
Support policies that incentivise longevity and health over maximum milk yield
Ask dairy producers about their average culling age and health metrics
Reduce dairy consumption or switch to plant-based alternatives to reduce overall demand
