Calf health as reflected in morbidity and mortality is a consistent and major issue facing the dairy farmer. Data from the USDA-NAHMS studies clearly show that dairy calf mortality remains above 8 percent year after year, representing a significant economic impact on the dairy farm economy. In addition, morbidity remains high, which adds to the economic burden through added labor and health supply costs. More than 50 percent of this morbidity is related to neonatal scours.
