Effects of sex and age of chickens upon cadmium retention were investigated in an experiment with 8 groups of chickens receiving 0.404 mg of Cd and another 8 groups receiving only 0.348 mg of Cd per 1 kg of consumed dry matter. From the mixture with a lower level of Cd, a significantly (P0.05) higher amount of this element was retained; percentage of deposited Cd in the organism was dependent on the source of Cd. Retention of cadmium and the content of this element in live body gain increased highly significantly (P0.01) with age. The growth rate of the total amount of Cd in the organism was higher than that of body weight. Allometric coefficients were 1.016+/-0.0129 and 1.099+/-0.0215 for chickens fed on diets with 0.404 and 0.348 mg of Cd, respectively. The difference was highly significant (P0.01). The effect of sex on the values under study was not significant.
