摘　　要：为加快适度规模和庭院养殖绵羊人工授精技术的推广,试验选择昌吉州辖区养殖集中农户56家(饲养2000只生产母羊),对公羊进行集中采精,选用2.5×浓缩型牛用精液稀释液对鲜精进行稀释,远距离(超过200 km)运输。母羊采取同期发情-定时输精方式分散输精,对比鲜精稀释平衡后运送距离对精液品质及母羊受胎率的影响。结果表明:运输距离在80~300 km、时间为1~4 h时对精液品质和母羊受胎率均无显著影响。In order to accelerate the promotion of artificial insemination in the sheep production in proper scale and in courtyard farming households,56 centralized farming households(raising 2000 ewes)in Changji Autonomous Prefecture were chosen for the experiment.The rams were collected in a centralized manner,and the fresh semen diluted with 2.5×concentrated bovine semen diluent and shipped over a long distance(more than 200 km).Ewes treated with estrus synchronization and timed insemination procedure during dispersed insemination.The effects of shipping distance of diluted and fresh semen on semen quality and conception rate were investigated.The results showed that shipping distance of 80~300 km and shipping time of 1~4 hours had no significant effect on semen quality and conception rate.
