Factors affecting magnesium absorption in relation to the aetiology of acute hypomagnesaemia

Abstract
The absorption of28Mg from the gastro-intestinal tract of sheep has been measured on both hay and spring grass diets, each of which supplied approximately the same amount of magnesium daily. A hypomagnesaemic response to the latter diet was accompanied by a reduction in the efficiency of magnesium absorption and was not merely due to the presence of bound magnesium in spring grass.
