Table 4 Ferritin protein and the iron1 concentration in the liver tissue in birds given "High Fe" diet (54 ppm Fe) and "Low Fe" (42 ppm Fe)(values are mean ± SEM, n = 6)

From: Biofortified red mottled beans (Phaseolus vulgaris L.) in a maize and bean diet provide more bioavailable iron than standard red mottled beans: Studies in poultry (Gallus gallus) and an in vitro digestion/Caco-2 model

Treatment diet Ferritin μg/g wet weight Iron μg/g wet weight Iron/Ferritin μmol
"High Fe" 425 ± 18a 48.1 ± 4.2a 68.5 ± 5.6a
"Low Fe" 409 ± 12a 39.5 ± 3.5a 59.8 ± 5.2a
  1. 1Atomic mass for iron is 55.8 g/mol.
