The premature culling of dairy cows for economic reasons before they reach their biological lifespan creates both welfare concerns and sustainability questions.
Dairy cow longevity is both an economic efficiency issue and a welfare issue. Cows culled after 3 lactations have not lived out even a fraction of their biological potential lifespan. The welfare concern is not the culling itself but the system conditions that create the health and fertility problems causing premature culling - metabolic disease from high-yield pressure, lameness from concrete floors and inadequate foot care, and reproductive failure from energy deficit. Improving longevity requires addressing these underlying welfare problems rather than simply accepting short productive lives as inevitable.
