摘　　要：为了探究不同繁殖力母羊发情周期血清中促卵泡激素(FSH)和促黄体激素(LH)分泌变化规律,试验选择新疆山羊高繁殖力母羊17只和低繁殖力母羊14只,采用酶联免疫分析法测定母羊发情周期血清中FSH和LH浓度。结果表明:高、低繁殖力母羊发情周期中FSH和LH浓度均呈脉冲波动式分泌,高繁殖力母羊血清中FSH浓度在发情周期第1,5,13,21天出现4个波峰,LH浓度在发情周期第2,5,11,21天出现4次波峰;低繁殖力母羊血清中FSH浓度在发情周期第1,5,21天出现3个波峰,LH浓度在发情周期第5,13,21天出现3次波峰。在发情期和发情前期母羊血清中FSH和LH浓度均高于发情后期和间情期,高、低繁殖力母羊血清中FSH和LH浓度均在发情前期(>17~21 d)开始升高,在发情期(0~48 h)当天达到峰值之后呈波动式下降趋势,且高繁殖力母羊发情周期4个阶段血清中FSH和LH浓度均高于低繁殖力母羊。高、低繁殖力母羊血清中FSH和LH基础浓度均在发情期最高,间情期最低。说明不同繁殖力新疆山羊母羊发情周期中FSH和LH分泌变化规律一致,高繁殖力母羊在整个发情周期中FSH和LH浓度高于低繁殖力母羊且波峰数量多于低繁殖力母羊。To investigate the changes of serum FSH and LH concentrations in different fertility ewes during the estrous cycle,17 high fertility ewes and 14 low fertility ewes from Xinjiang goats were selected for the experiment,and the concentrations of FSH and LH in the blood serum were determined by enzyme-linked immunosorbent assay(ELISA).The results showed that both FSH and LH concentrations in the blood of high and low fertility ewes showed pulsatile secretion during the estrous cycle.Serum FSH concentration of high fertility ewes showed four peaks on days 1,5,13 and 21 of the estrous cycle,and LH concentration showed four peaks on days 2,5,11 and 21 of the estrous cycle.Serum FSH concentration of low fertility ewe showed 3 peaks on days 1,5 and 21 of the estrus cycle,and LH concentration showed 3 peaks on days 5,13 and 21 of the estrus cycle.The serum concentrations of FSH and LH in estrus and preestrus were higher than those in late estrus and interestrus.The concentrations of FSH and LH in the serum of high and low reproductive ewes begin to increase during the preestrus period(>17-21 days)and reach their peak on the day of estrus(0-48 hours).The concentrations of FSH and LH in the serum of high reproductive ewes during the four stages of the estrus cycle are higher than those of low reproductive ewes.The basal concentrations of FSH and LH in serum of high and low fertility ewes were the highest in estrus and the lowest in interestrus.These results indicated that the changes of FSH and LH secretion were consistent in estrus cycle of Xinjiang goats with different fecundity;in the whole estrus cycle,the concentration of FSH and LH in high fertility ewes was higher than that in low fertility ewes,and the number of crest was higher than that in low-fecundity ewes.
