摘　　要：将45只辽宁绒山羊平均分为3个组:A、B、C,按如下程序进行同期发情处理,A:CIDR+PMSG+FSH+PG(CIDR埋植12d);B:CIDR+FSH+PG(CIDR埋植12d);C:CIDR+PMSG+FSH+PG(CIDR埋植16d)。结果表明:(1)超排时加注250IUPMSG撤栓后48h内的同期发情率显著提高(试验组A:86.7%VS试验组B:73.3%,P<0.05);(2)撤栓后48h内的同期发情率埋栓16d组高于埋栓12d组,但两组间差异不显著(试验组A:86.7%VS试验组C:93.3%,P>0.05)。45 Liaoning cashmere goats were. divided into 3 groups：A ,B.C ,The estrus of goats were synchronized as the following protocols： A：CIDR＋PMSG＋FSH＋PG （CIDR was inserted for 12d）;B：CIDR＋FSH＋PG （CIDR was inserted for 12d）;C：CIDR＋PMSG＋FSH＋PG （CIDR was inserted for 16d）.The results indicated that the rate of estrus synchronization was significant improved by injected PMSG 250IU at the beginning of superovulation （Agroup：86.7% VS B-group：73.3%,P〈0.05）;The estrus rate of treatment C higher than treatment A, but with no significant difference（A-group：86.7% VS C-group：93.3%, P〉0.05）.
