The amount of iron absorbed by the untreated animals over a 3-day period is compared with the amount of iron excreted by the treated animals over a 3-day period. Net iron balance = dietary iron intake − (urinary iron + fecal iron). Animals in a negative iron balance are excreting more iron than they are absorbing.
