Extended calf rearing programs that allow longer contact with mothers or groupmates produce calves with better welfare outcomes and potentially better adult productivity.
Extended rearing programs that delay weaning and provide social housing produce calves with measurably better welfare and development compared to conventional early individual housing. These calves are less fearful, more exploratory, and show better cognitive performance. The welfare benefits of extended rearing extend into adult life, producing dairy cows that are better equipped to cope with the challenges of commercial production.
