The effect of dietary iron loading on biliary iron excretion was investigated with male Wistar rats aged 6 wk. The rats were fed purified diets with either 174 or 1740 mg FeSO4. 7H2O/kg diet and demineralized water for 6 wk. Blood haemoglobin, hematocrit, and iron concentrations in kidney and heart were not affected and iron concentrations in liver, spleen, and tibia were significantly raised after feeding the high-iron diet. The high-iron diet did not raise biliary iron excretion, suggesting that biliary iron excretion does not play an important role in regulating iron metabolism in rat after dietary iron loading.
