Excretion of Labelled Magnesium by the Sheep


KNOWLEDGE of the routes by which magnesium is excreted by the ruminant and the mechanism of control of such excretion is of value in connection with the ætiology of hypomagnesæmia. The work to be described is of a preliminary nature owing to the high cost of the radioisotope used. It includes a determination of the endogenous fæcal magnesium excretion and its comparison with renal magnesium excretion.
