Abstract:
Five iron nutritional resources were chemically determined for twelve nutrients and three deleterious items. It was found that they contained 36 to 432 mg% iron and 48 to 67 g% protein. The relative biological value (RBV) of iron of rabbit liver powder, poultry liver powder, fish liver powder, pig liver powder and yeast powder were 88.5%, 85.5%, 48.0% and 132.5% respectively, as measured by prophylactic assay in rats (using ferrous sulfate as reference standard). Most of these resources are common foods, thus these must be of no trouble for infant iron supplements and easily acceptable for their mothers.
