Adequate colostrum management in the first hours of a calf's life is the single most important intervention for preventing disease and ensuring welfare through the critical neonatal period.
Failure of passive transfer leaves calves immunologically vulnerable to all infectious diseases in their environment. Calves with inadequate passive immunity suffer higher rates of septicemia, pneumonia, diarrhea, and joint ill with associated pain, disability, and death. The consequences of inadequate colostrum management extend throughout the calf's life as early disease increases susceptibility to subsequent disease. Ensuring every calf receives adequate quality colostrum within the first hours of life is one of the highest-return welfare and health investments on any cattle farm. It is a basic obligation of responsible calf management.
