【摘要】：為研究儋州雞不同產(chǎn)蛋時(shí)期生殖激素的分泌規(guī)律,采用ELISA方法對(duì)儋州雞母雞開(kāi)產(chǎn)前期、開(kāi)產(chǎn)期、產(chǎn)蛋高峰期及產(chǎn)蛋后期4個(gè)時(shí)期血液中促卵泡素(FSH)、促黃體生成素(LH)、催乳素(PRL)、孕酮(P)、雌二醇(E_2)的濃度進(jìn)行測(cè)定。結(jié)果顯示,開(kāi)產(chǎn)期與產(chǎn)蛋高峰期FSH與LH濃度極顯著高于開(kāi)產(chǎn)前期和產(chǎn)蛋后期(P0.01);不同產(chǎn)蛋時(shí)期血液中PRL濃度呈上升趨勢(shì),且開(kāi)產(chǎn)前期和開(kāi)產(chǎn)期PRL濃度顯著低于產(chǎn)蛋后期(P0.05);不同產(chǎn)蛋時(shí)期血液中E_2濃度呈下降趨勢(shì),且產(chǎn)蛋后期E_2濃度顯著高于開(kāi)產(chǎn)前期和開(kāi)產(chǎn)期(P0.05),極顯著高于產(chǎn)蛋高峰期(P0.01);開(kāi)產(chǎn)期與產(chǎn)蛋后期P的濃度較高,均顯著高于開(kāi)產(chǎn)前期(P0.05),且極顯著高于產(chǎn)蛋高峰期(P0.01)。研究表明,儋州雞在不同產(chǎn)蛋時(shí)期血液中生殖激素含量水平有不同的變化,開(kāi)產(chǎn)期血液中FSH、LH及P濃度較開(kāi)產(chǎn)前期明顯升高;產(chǎn)蛋高峰期血液中FSH與LH的濃度高于其他時(shí)期;產(chǎn)蛋后期血液中PRL、E_2、P的濃度較產(chǎn)蛋高峰期明顯上升,且負(fù)反饋調(diào)節(jié)FSH與LH的分泌量。
[Abstract]:In order to study the secretion of reproductive hormones in Danzhou hens at different laying stages, ELISA method was used to study the follicular hormone (FSH), (LH), in the blood of Danzhou hens at the early stage of labor, the opening period, the peak period of laying eggs and the late stage of laying. The concentration of prolactin (PRL), progesterone (P), estradiol (E 鈮，
