The increased concern of modern societies on the emergence of antibiotic-resistant bacteria has led regulatory institutions to minimize the number of antibiotics that can be used in food-producing animals for therapeutic and preventive treatment of infectious diseases.

An important factor in calfhood health is the presence of maternal antibodies in calf serum during the critical first few weeks of life for protection from disease. One study shows that compared to maternal colostrum, feeding a lacteal-derived colostrum replacer provides a more uniform range of antibody titres to some common respiratory viruses affecting calves. Feeding a colostrum replacer may allow for better prediction of vaccination schedules and reduced incidence of disease in a herd.
