Dairy Cow Longevity and Lifetime Welfare

Average dairy cow productive life is 2.5 lactations before culling. Improving longevity improves lifetime welfare and reduces the environmental cost of replacement.

Key Facts

Average UK dairy cow lifespan is 5-6 years despite biological potential for 15-20 years
Mastitis, lameness, and reproductive failure are the primary reasons for early culling
Cows surviving to 4+ lactations have lower disease rates and higher productivity per lifetime
Longevity improvement reduces the need for replacement heifers and associated welfare costs
Genetic selection for longevity traits is increasingly incorporated into breeding value calculations

Welfare Considerations

Dairy cow lifetime welfare is significantly compromised by high culling rates from preventable conditions. A cow culled at 2.5 lactations for lameness or mastitis has experienced poor welfare that ended her life prematurely. Improving longevity through disease prevention, better housing, and genetic selection simultaneously improves individual welfare, reduces environmental impact, and increases economic returns.
