The short productive lives of modern dairy cows — often culled after just 2 to 3 lactations — reflect a welfare failure rooted in production pressure, and extending productive life improves both animal welfare and farm sustainability.
The short productive lives of commercial dairy cows are a welfare problem embedded in the economics of the industry. High milk yields are associated with metabolic stress, immune suppression, and elevated disease risk — the same characteristics that lead to early culling. Farms that prioritize cow longevity — through good nutrition, comfortable housing, proactive disease management, and reduced metabolic stress — achieve both better welfare and better economics through reduced replacement costs and higher milk per lifetime. Welfare assessments that include productive lifespan as a key indicator capture the cumulative effect of management decisions across a cows life and incentivize systems that genuinely support long-term health.
