The average commercial dairy cow lives approximately 5 years before culling — far less than her natural lifespan of 20+ years. Improving dairy cow longevity through better health management is a welfare and economic priority.
Dairy cow longevity welfare reflects the cumulative burden of health problems that cause early death or forced culling before cows reach even a fraction of their natural lifespan. Chronic lameness, mastitis, reproductive failure, and metabolic disease are not inevitable — they are management-related conditions whose prevalence can be dramatically reduced through better housing, nutrition, health monitoring, and breeding. Cows that are chronically lame, repeatedly mastitic, or reproductively failed experience ongoing welfare compromise before eventual culling. Higher-welfare systems that prioritize preventive health management achieve significantly better longevity — some Swedish and Nordic herds routinely achieve productive lives exceeding 7 years. The economic incentive aligns with welfare — longer-lived cows are more profitable because they have more lactations to amortize the rearing cost.
