Abstract


The effects of iodocasein, tapazole, and diethylstilbestrol in the thyroidal activity of chicken were tested. Iodocasein and tapazole were mixed with basal ration at the levels of 0 17 and 0.01 per cent respectively and were fed to one-weeks-old chicken for two months. Six milligrams of diethylstilbestrol were implanted in the subcutaneous tissue. Subsequently 10 uci of radioactive iodine I^(131) were injected intramuscularly into each of the chicken to measure the thyroidal activities of the chicken one month after the treatment was started.
The results obtained were as follows .
1) The thyroidal uptake of I^(131) was not observed in the iodocasein group
2) The highest thyroidal uptake rates of I were shown twelve hours after the injection in the al1 groups except the iodocasein group.
3) The higher thyroidal uptake rates of I were observed in the female chicken than in the male chicken(P<0.01) of the control and the tapazole groups. llowcver, the signific3711 difference between the two sexes was not found in the diethylstilbestrol group.
4) Tapazole at the level of 0.01 per cent of the basal rantion of the chicken increased the thyroidal activity slightly.
