Modern dairy farming creates significant welfare challenges for cows through selective breeding for extreme milk yields, routine separation of calves from mothers and housing conditions that restrict natural behavior.
Dairy cow welfare is characterized by a cluster of interconnected problems driven by the extreme production demands placed on modern high-yielding breeds. Mastitis causes acute pain in the engorged, infected udder and requires antibiotic treatment that temporarily removes milk from the supply chain. Lameness from hoof disease and leg joint problems causes chronic pain that suppresses feeding and social behavior. The metabolic demands of high milk production create systemic physiological stress. Calf separation, while standard practice, causes evident grief in both cow and calf. Higher welfare dairy farming — through slower-producing breeds, meaningful outdoor access, cow-calf contact systems and proactive lameness and mastitis management — is possible and practiced on a small but growing number of farms.
