The immediate post-birth period is critical for dairy calf welfare, with colostrum intake, thermal comfort, and early social experience setting the foundation for lifetime health outcomes.
The welfare implications of dairy calf management begin before birth - maternal nutrition, calving assistance quality, and calving pen design all affect calf vitality and survival. In the immediate post-birth period, adequate colostrum intake (at least 3 liters within the first 6 hours) is a welfare imperative since failure of passive transfer creates an immunologically vulnerable animal susceptible to disease throughout its productive life. The separation of cow and calf, while standard in conventional dairying, causes vocalizations and stress indicators in both animals that persist for days, raising fundamental welfare questions about the practice that dam-rearing research is beginning to address.
