Colostrum management in the first hours of a dairy calf's life determines immune status and welfare outcomes across the entire production period.
Colostrum welfare represents the single most important welfare intervention in the first hours of a calf's life. The narrow window for passive immunity transfer means that delays - from difficult calving, slow-to-suck calves, or management inattention - directly translate into compromised immune status that increases disease susceptibility and welfare compromise across the calf's entire production life. Investment in colostrum quality testing, adequate volume provision, and prompt administration is both economically and welfare-justified. The preventability of Failure of Passive Transfer through management attention makes it a particularly important welfare target.
