How dairy calves are managed from birth through weaning has profound welfare implications. The shift toward enhanced milk feeding, social housing, and gradual weaning represents a significant welfare improvement over conventional systems.
Calf welfare in dairy systems has historically been overlooked as attention focused on cow welfare and milk production. The separation of cow and calf, while economically motivated, causes measurable acute distress. Research-driven improvements — enhanced milk feeding, social group housing, and gradual weaning — improve calf welfare significantly and often improve growth performance simultaneously. The welfare of male dairy calves (typically unwanted in a milk-production system) is a growing ethical focus, with campaigns against culling at birth and for investment in beef-dairy cross breeding programs.
