摘　　要：[Objeclive] The comparison of levels of thyroid hormones （T3, T4 and FT3） in female ducks serum and embryo of different embryonic age between Gaoyou duck and Jinding duck were made to provide basic data for further research. [Method] The levels of thyroid hormones （T3, T4 and FT3） in female ducks serum, fertilized eggs, and 7, 11,15, 19, 22, 28-days embryo of Gaoyou duck and Jinding duck were analyzed with radioimmunoassay （RIA）. [ Result]The levels of thyroid hormones in fertilized eggs were higher than those in serum of female ducks; different em- bryonic age hormone level of Gaoyou duck and Jinding duck in serum had almost the same variation trend, which was low but relatively stable after 15 days. [Condusion] The result suggested that thyroid hormones play an important role in duck embryonic development, especially in the early peded.[Objeclive] The comparison of levels of thyroid hormones （T3, T4 and FT3） in female ducks serum and embryo of different embryonic age between Gaoyou duck and Jinding duck were made to provide basic data for further research.
