The aim of this study was to evaluate the practicability of using the metabolic profile test (MPT) as a preventive tool for periparturient disease of dairy cows. The MPT was assessed in 79 dairy herds with high incidence of periparturient disease and 76 healthy herds of cows producing more than 8,500 kg 305-day milk yield. The changes in metabolic profiles were also assessed in 17 dairy herds at two times, the first at high incidence of periparturient disease and the second after reduced incidence and improved feeding management. In the herds with high incidence of periparturient disease, low blood values of hematocrit, albumin, glucose, cholesterol, calcium and magnesium were observed in the dry period. These values correctly diagnosed malnutrition as the cause of periparturient diseases. Following feeding management changes, there was a low incidence of periparturient disease and the metabolic profiles were normal showing that feeding management had improved. We concluded that the MPT is a useful tool for assessing feeding management and periparturient diseases of dairy cows.
