摘　　要：【目的】旨在提升湖羊繁殖效率以及优质种公羊利用率,推动湖羊腹腔镜输精技术的广泛应用。【方法】选取550只健康湖羊作为试验对象,分为三组进行不同的同期发情处理后实施腹腔镜输精,进而观察同期处理和腹腔镜输精的效果。【结果】“CIDR+PMSG+PGF2α+A3”法的同期发情率显著高于“CIDR+PGF2α+A3”法(P<0.05),“CIDR+PMSG+PGF2α+A3”法的初产母羊和经产母羊的同期发情率差异不显著(P>0.05),且初产母羊的受胎率略高于经产母羊;“CIDR+PMSG+PGF2α+A3”法同期发情处理的腹腔镜输精受胎率略高于“CIDR+PGF2α+A3”法,但差异不显著(P>0.05)。【结论】采用“CIDR+PMSG+PGF2α+A3”法进行同期发情处理并实施腹腔镜输精,在提高湖羊同期发情率和腹腔镜输精受胎率方面具有一定优势,但仍需进一步优化同期处理方案,深入探究影响湖羊受胎率的因素,以提升湖羊腹腔镜输精的效果。【Objective】This study aimed to enhance the reproductive efficiency of Hu sheep and the utilization rate of high-quality breeding rams,and to promote the wide application of laparoscopic insemination technology for Hu sheep.【Methods】550 healthy Hu sheep were selected as the experimental animals and divided into three groups for different estrus synchronization treatments followed by laparoscopic insemination,and then the effects of estrus synchronization treatment and laparoscopic insemination were observed.【Results】The estrus synchronization rate of the"CIDR+PMSG+PGF2α+A3"method was significantly higher than that of the"CIDR+PGF2α+A3"method(P<0.05),and there was no significant difference in the estrus synchronization rate between primiparous ewes and multiparous ewes;the conception rate of primiparous ewes was slightly higher than that of multiparous ewes,with no significant difference(P>0.05);the conception rate by laparoscopic insemination with estrus synchronization treatment using the"CIDR+PMSG+PGF2α+A3"method was slightly higher than that of the"CIDR+PGF2α+A3"method,with no significant difference(P>0.05).【Conclusion】The pretreatment with the"CIDR+PMSG+PGF2α+A3"method and the implementation of laparoscopic insemination had certain advantages in improving the estrus synchronization rate and the conception rate of Hu sheep.However,the estrus synchronization treatment still needed to be further optimized,and the factors affecting the conception rate needed to be further explored to enhance the effect of laparoscopic insemination in Hu sheep.
