"The utilisation of dietary iron was examined in cockerels of laying and meat type hybrids from 3 to 100 days of age within 46 subsequent balance periods. Chickens were fed ad libitum on a diet with the content of 312 mg of Fe per 1 kg. The dependence of Fe utilisation upon age was expressed by the convex parabolas with minimum values in the tenth week of age. The dependence of Fe content in body gain on age was highly significant (P < 0.01). The course of this dependence was expressed by parabolas with minimum values on Day 38 and Day 28 in slow and fast growing chickens, resp. The growth rate of total amount of Fe in the body was by 6 per cent lower (P < 0.01) than that of body weight of chickens." . . "2"^^ . . "2"^^ . "VI. K\u00E1brtovy dietetick\u00E9 dny" .
