Abstract
The balances of calcium, phosphorus and magnesium were studied in young rats, using a combination of magnesium and phosphorus at each level.
The effects of changes in dietary magnesium on calcium and phosphorus balance was dependent on the dietary magnesium concentration. Increases in dietary magnesium reduced the apparent absorption of calcium and phosphorus and in respect of the fecal excretion rate a certain tendency was observed, namely high intake of magnesium seemed to induce an increase in phosphorus excretion as compared with calcium excretion. High intake of phosphorus lowered the apparent absorption of magnesium but did not affect the calcium balance.
