Development of nutritional iron deficiency in growing male rats: haematological parameters, iron bioavailability and oxidative defence.

Despite Fe deficiency having been widely studied, the sequence of events in its development still remains unclear. The aim of the present study was to elucidate the effects of nutritional Fe-deficiency development on haematological parameters, Fe bioavailability and the enzymes involved in oxidative defence in recently weaned male Wistar albino rats. Control (C) and Fe-deficient (ID) groups were fed the AIN-93 G diet with a normal Fe level (45 mg/kg diet) or with a low Fe level (5 mg/kg diet), respectively, for 20, 30 or 40 d.
