皖西白鹅雄鹅种龄与生殖激素水平关系的研究

The Research on Gander concerning Seed Age and reproductive Hormone Level of Wanxi White Goose

实验结果显示,各龄雄鹅在非生殖期血清中促黄体生成素(LH)、促卵泡刺激素(FSH)和雌二醇(E2)在血清中的含量都低于5.0 mu/ml,其差异性难以比较。4种不同种龄的雄鹅在垂体泌乳素(PRL)和孕酮(P)水平上没有显著差异。在睾酮(T)激素水平上差异很明显,即2龄种鹅>1龄种鹅>3龄种鹅>4龄种鹅。可见在4个种龄的雄鹅中,2龄种鹅体内的睾酮最高,其生殖能力可能最强。

According to the experiment, the content of luteinizing hormone （LH）, follicular stimulating hormone（FSH） and estradio （E2） all below 5.0mu/ml of gander during non reproductive stage,so it was difficult to find the distinction of them and there was also no tremendous difference between prolactin （PRL） and progesterone （P） while the remarkable difference could be found in testosterone （T） that was,2 seed-age phase over 1 seed age phase in the same way, 1 seed-age over 3seed age phase and 3 seed-age phase over 4 seed-age phase. Obviously the testosterone reached its summit in the 2 seed stage and most likely had the most energetic reproductive capacity.
