摘　　要：为比较多胎与单胎绵羊妊娠早期生殖内分泌的差异，应用酶免疫测定法（EIA）和放射免疫测定法（RIA）检测江苏湖羊和新疆细毛羊妊娠早期血清孕酮（P）、雌二醇（E2）、促黄体素（LH）、前列腺素和瘦素水平。试验结果表明：湖羊血清孕酮、瘦素水平在妊娠13～43d极显著高于新疆细毛羊（P〈0．01），血清前列腺素水平在妊娠13～30d极显著低于新疆细毛羊（P〈0．01），而雌二醇、促黄体素水平在妊娠13～43d与新疆细毛羊无显著差异（P〉0．05）。这为湖羊多胎作用机制的研究提供了参考。To compare the endocrinology during early pregnancy of the Hu-sheep and Xinjiang Fine Wool Sheep, five hormones were examined by enzyme immunoassay （EIA） and radio immunoassay （RIA）. The results showed that the levels of serum progesterone （P） and leptin in the Hu-sheep were significantly higher than those in the Xinjiang Fine Wool Sheep during day 13 -43 of pregnancy （P 〈0. 01 ）, while the level of prostaglandin was significantly lower during day 13 - 30 of pregnancy （ P 〈0. 01 ）, and the levels of luteinzing hormone （ LH ） and estradiol （ E2 ） were not different between the two sheep breeds. These results provided the basic for the research of fecundity mechanism.
