	abstract = {Urinary magnesium concentrations in dairy cows follow a distinct seasonal pattern, being high during the summer and lowest during August and September, coinciding with the period when the incidence of hypomagnesaemia is at its greatest. During this critical period mean urinary Mg concentrations (Y, mg/mg creatinine) measured weekly were related to mean plasma Mg concentrations (X, mM) by expression in Y= - 7.5 + 6.2X (R},
