In order to study T3 and T4 hormones followed by oral administration of three different doses of vitamin D (IU1000, IU3000 and IU 5000 kg live weight per day). 180 fry of common carp (Cyprinus carpio) weighing 25-20 g, were divided into four treatments and three replicates of 15 fish were randomly selected in a test environment. 60 days fish were fed diets fortified with vitamin D. At day 30 and day 60, the fish samples were collected and serum obtained from the blood samples to the laboratory for examination and study of hormones, T3 and T4 were transferred to the ELISA test to measure the levels of these hormones. The results of this study indicated that thyroid hormones in common carp (Cyprinus carpio), almost under the influence of oral administration of vitamin D correcting and omitting the over words have been. T3 so that the amount of treatment (IU3000) and treatment (IU5000), 30 R showed a significant decrease compared to controls. However T3 rate at the end of a significant difference compared with control and other treatments did not continue to take vitamin D, increasing its level in the tree (IU3000 and IU5000) on day 60 of the study saw the highest level of treatment (IU5000 ) was. But T4 hormones in middle or at the end of the period, was not affected by vitamin D added to the feed.
