    Abstract / Zusammenfassung

    Dairy cows may suffer events of hypocalcemia and hypomagnesemia, commonly known as milk fever and tetany. Milk fever is characterized by hypocalcemia at parturition as a consequence of a sudden increase in Ca demand and an unavoidable delay in Ca metabolism adaptation. Tetany is due to impaired Mg absorption from the rumen that cannot be compensated by absorptive or excretory adaptation, resulting in a net nutritional shortage of Mg and culminating in hypomagnesemia. Prevention strategies require triggering the activation of Ca gastrointestinal absorption and avoiding factors limiting ruminal Mg absorption.
