The calcium (Ca) balance was studies in four strains of rat (Wistar, Fischer, Sprague-Dawley and Donryu), maintained on either a diet, supplemented with Harper mineral mixture or a diet supplemented AIN-76 mineral mixture. Six rats from each experimental group were killed after 21 days of diet feeding. During 16 to 21 days excreta were collected separately from each rat. The measurement of Ca were performed by the method of atomic absorption spectrometry. The amounts of food intake were significantly increased or decreased according to strain difference, but not affected by the rats of mineral mixture supplemented to diet. The major cause for the variation of Ca balance was due to the change of food intake according to strain difference. The effect of mineral mixture on Ca balance might be dependent on dietary content of Ca, but not on urinary Ca excretion.
