【摘要】：为了研究福清山羊和戴云山羊发情周期内生殖激素的分泌变化规律,采用Elisa方法检测了2个品种经产母羊整个发情周期内外周血中4种生殖激素(雌二醇、孕酮、促卵泡激素、促黄体激素)的浓度。结果表明,2个品种发情周期内血浆FSH、LH均呈现周期性波动式分泌,福清山羊在发情周期中出现了4次波峰而戴云山羊为5次。2个品种血浆E_2的分泌水平呈现明显的高、低2个分泌时期,2个分泌时期血浆E_2浓度差异达到极显著水平(P0.01),戴云山羊高分泌期的E_2浓度显著高于福清山羊(P0.05)。2个品种血浆P浓度在发情期、发情前后2~3d较低,到发情周期的第6d开始分泌量迅速增加,在发情周期第8~9d达到整个发情周期的最大峰值,极显著高于发情期血浆P浓度(P0.01),随后在较高浓度范围内呈波动分泌至发情周期第16d,之后迅速下降至发情期的低分泌水平。
[Abstract]:In order to study the changes of reproductive hormone secretion in estrous cycle of Fuqing goat and Dai Yunshan goat, four kinds of reproductive hormones (estradiol, progesterone, follicle stimulating hormone) in peripheral blood of two breeds of estrous estrous sheep were detected by Elisa method. The results showed that the plasma FSH LH secreted periodically during estrus cycle. There were 4 peaks in estrous cycle in Fuqing goat and 5 in Dai Yunshan goat. The difference of plasma E _ 2 concentration between two secretory periods and two secretory periods reached a very significant level (P _ (0.01)). The concentration of E _ (2) in high secretory phase of Dai Yunshan goat was significantly higher than that in Fuqing goat (P _ (0.05)). The plasma P concentration of the two breeds was lower during estrus and 2 days before and after estrus. At the 6th day of estrus cycle, the secretion increased rapidly, and reached the maximum value of the whole estrus cycle on the 8th and 9th day of estrus cycle. The plasma P concentration was significantly higher than that in estrus, and then fluctuated to the 16th day of estrus cycle, and then decreased to the low secretion level in estrus period.
