The metabolic profile test: its practicability in assessing feeding management and periparturient diseases in high yielding commercial dairy herds.

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