The Colostrum Counsel – Colostrum Beyond the First Feeding: Supporting Calves Through Diarrhea
September 2025
As the dairy industry continues to evolve under the pressure of antimicrobial resistance, producers are seeking alternatives to traditional antibiotic therapies, especially for common calfhood diseases like diarrhea. One promising solution is colostrum, not just as a preventive measure, but as an intervention during cases of diarrhea. Diarrhea remains the leading cause of morbidity and mortality in preweaned calves, often triggered by a complex interplay of environmental, management, and pathogenic factors. While prevention is paramount, ensuring adequate colostrum intake at birth, maintaining hygiene, and minimizing stress, supportive therapy is critical when diarrhea does occur.
