Dairy Cow Longevity and Welfare Economics

Improving dairy cow longevity reduces replacement costs, improves lifetime welfare and delivers production system benefits.

Key Facts

Average UK dairy cow productive lifespan is approximately 2.5 lactations before culling
Low longevity is driven by lameness, mastitis, reproductive failure and other welfare-linked conditions
Each additional lactation reduces the environmental footprint per litre of milk produced
Extended longevity programmes focus on lameness prevention, metabolic health and foot health
Genomic selection for health traits including longevity is available in major dairy breeds

Welfare Considerations

Low longevity indicates a production system where cows are failing due to preventable disease and injury. High culling rates represent both a welfare failure and an economic cost. Improving longevity by preventing the diseases that cause early culling simultaneously improves animal welfare and farm profitability, creating a powerful business case for welfare investment.

What You Can Do

Support dairy farm assurance schemes that include longevity and culling rate reporting
Choose dairy products from farms with documented low culling rates and health programmes
Advocate for inclusion of longevity indicators in sustainable farming subsidy criteria
