摘要
比较高繁殖力的济宁青山羊和低繁殖力的沂蒙黑山羊年周期血浆中促卵泡素(FSH)和促黄体素(LH)的分泌变化规律,分析FSH和LH与山羊繁殖力之间的关系。采用放射免疫分析法(RIA)测定血浆中FSH和LH浓度,结果表明:济宁青山羊和沂蒙黑山羊血浆中FSH和LH浓度都存在季节性变化,即秋季最高,春季次之,夏季最低;济宁青山羊和沂蒙黑山羊全年各月血浆中FSH和LH的分泌呈波浪式变化;高繁殖力的济宁青山羊各月份和4个季节血浆中FSH浓度均高于低繁殖力的沂蒙黑山羊,但尚未达到显著水平(P>0.05),2种山羊血浆中LH浓度各月份和4个季节基本无差别。
The concentrations of LH and FSH in blood plasma were measured by radioimmunoassay during the annual cycle of two local goat breeds in Shandong with low（Yimeng Black goat） and high（Jining Gray goat） fecundity.The results showed that the secretion of the two hormones in each breed changed with season obviously which was highest in autumn,secondary in spring and lowest in summer.FSH and LH levels in plasma showed a wave pattern in each breed during twelve months.The mean concentration of FSH was higher in Jining Gray goat than that in Yimeng Black goat in different month or season,but it was not significant（P〉0.05）.The level of LH in plasma was similar in the two breeds.
