Average dairy cow culling age in the UK is around 5-6 years, far below their 20-year natural lifespan, with significant welfare implications and economic costs.
Dairy cow welfare and longevity are deeply interconnected. Premature culling driven by preventable disease (lameness, mastitis) represents both a welfare failure - the disease caused suffering before culling - and a lost opportunity for a longer, healthier productive life. Farms that invest in welfare improvements including better hoof care, mastitis prevention, and transition period management achieve longer herd lifespans, lower culling rates, and better economic outcomes. The welfare and sustainability agendas are aligned: a longer-lived cow is both more welfare-positive and more resource-efficient.
