The objectives of the present study were to determine iron(Fe) balance of four strains of young male rat. The strains tested were Wistar, Fischer, Sprague-Dawley and Donryu rats. Rats from each strain were divided into two groups and fed either a diet supplemented with Harper's mineral mixture or a diet supplemented with AIN-76 mineral mixture. Dietary mineral mixture was set at 4.0% for each diet. The measurement of Fe were performed by the method of atomicabsorption spectroscopy. The net absorption of iron was calculated from iron balance, ie, net absorption, % = (Fe intake-fecal Fe)/Fe intake × 100. All data were examined by the analysis of variance. Food intake was no siginificant difference both a diet supplemented with Harper's mineral mixture and a diet supplemented with-AIN-76 mineral mixture. The strain difference affected significantly fecal and urinary Fe excretion, Fe absorption and Fe balance. However, fecal Fe excretion and Fe balance was not affected significantly by change of the mineral mixture. No strain difference resulted in a significant change in comparison with Fe balance per weight gain during balance study.
