Dairy cows are among the most numerous large mammals on Earth, and improving their welfare is one of the highest-impact opportunities in farm animal advocacy.
Dairy cow welfare is compromised by the combination of extreme genetic selection for milk production and management systems that prioritize productivity over animal wellbeing. High-producing cows are physiologically stressed by the demands of lactation, with immune function compromised and energy balance negative in early lactation. Lameness - often from concrete housing and hoof problems - affects tens of millions of cows globally and causes chronic pain that reduces mobility, feeding behavior, and social interaction. Mastitis causes acute and chronic pain and is often inadequately treated. The separation of cows from their calves causes documented distress in both. Meaningful welfare improvements are achievable - pasture access, effective lameness management, extended calf contact, pain relief for all procedures, and selection for health over extreme production all represent real improvements for real animals.
