摘要
对番鸭就巢期不同时间的血浆生殖激素水平进行测试,揭示了不同就巢时间血浆生殖激素浓度变化的规律,并对就巢与激素之间的相关性进行分析。结果表明:(1)抱窝期血浆PRL含量(0.68±0.11ng/mL)极显著高于醒抱期的含量(0.33±0.04ng/mL)(P<0.01);(2)醒抱前后血浆LH含量差异很大,醒抱后LH含量(33.17±15.49mIU/mL)极显著高于抱窝期含量(5.56±1.99mIU/mL)(P<0.01);(3)抱窝期血浆E2含量(0.9±0.65ng/mL)极显著低于醒抱期含量(1.9±1.17ng/mL)(P<0.01);(4)PRL与LH、PRL与E2、LH与E2之间的相关系数分别为-0.923、-0.666和0.641。
The concentrations of plasma reproductive hormone were determined during the broody period, in order to show the change regularity of the concentrations of plasma reproductive hormone and the (relationship) between broody and hormone. The results showed: Firstly, the concentrations of plasma PRL(0.68±0.11 ng/mL) during the broody period were significantly higher than those (0.33±0.04 ng/mL) during the ovulatory period. Secondly, there were obvious differences in the concentrations of plasma LH between the ovulatory period and the broody period, the concentrations of LH(33.17±15.49 mIU/mL) during the ovulatory period were significantly higher than those(5.56±1.99 mIU/mL) during the broody period. Thirdly, the concentrations of plasma E_2(0.9±0.65 ng/mL) during the broody period were significantly lower than those(1.9±1.17 ng/mL) during the ovulatory period. Fourthly, the correlation coefficients between PRL and LH,PRL and E_2,LH and E_2 were -0.923?-0.666 and 0.641 respectively.
