摘　　要：[目的]为建立适合于奶山羊同期发情的技术方案。[方法]本试验通过不同孕酮栓与激素类别、不同处理方案、不同季节和不同胎次对奶山羊同期发情效果进行探讨。[结果]使用“第0d,14:00放置PRID;第9 d,14:00肌内注射PMSG330IU;第11d,14:00撤栓,同时肌内注射PG0.2mg;第12d,20:00试情”的同期发情处理程序,在奶山羊自然发情旺季(10月至次年2月)对一胎和二胎母羊进行同期发情处理,发情率可达81%以上,且成本相对较低。[结论]通过该方案对内蒙古地区奶山羊规模化养殖场开展同期发情,操作简便,成本较低,可获得较高的发情率。[Objective]In order to establish a technical scheme suitable for estrus synchronization of dairy goats.[Method]This experiment explored the effect of estrus synchronization of dairy goats through different progesterone suppositories and hormone types,different treatment schemes,different seasons and different parities.[Results]That the PRID was placed on the 0th day,14:00;on the 9th day,PMSG 330 IU was injected intramuscularly at 14:00.On the 11th day,the thrombus was removed at 14:00,and PG 0.2 mg was injected intramuscularly.On the 12th day,the estrus synchronization procedure of 20:00 was performed on the first and second parity ewes in the natural estrus season of dairy goats(October-February of the next year).The estrus rate can reach more than 81%,and the cost is relatively low,which is suitable for large-scale dairy goat farms in Inner Mongolia.[Conclusion]Therefore,we can carry out the estrussynchronous in large-scale dairy goats farms in Inner Mongolia by this scheme,which is easy to operate,cost-effective,and can achieve a high estrus rate.
