Modern dairy cows are often culled after just 2-3 lactations despite a natural lifespan of 20 years. Improving longevity through better welfare management benefits both cows and farm sustainability.
Short dairy cow lifespans reflect chronic welfare deficits: lameness, mastitis, and metabolic disease that compromise health and productivity until cows are culled. These conditions cause significant suffering throughout their abbreviated productive lives. Longevity-focused management prioritizes cow health over maximum yield, reducing disease incidence and allowing cows to live and produce longer. This is simultaneously better for welfare, farm economics, and environmental sustainability. Welfare improvements including comfortable housing, attention to locomotion scoring, preventive health programs, and reduced reliance on high-energy rations to push milk yield address the root causes of early culling.
