摘要
以甘肃舍饲养殖的小尾寒羊为试验对象,分别采用CIDR栓+PMSG(试验组I)、PG+PMSG试(验组II)、PG+CIDR栓+FSH(试验组III)3种不同的组合方式进行非繁殖季节同期发情诱导试验。结果表明:3个试验组在72h内的同期发情率均在85%以上,其中试验组I在72h内发情率达到94.95%,显著高于另外两组,但其单只羊的诱导成本也最高。试验组II的成本最低,试验组III的发情率在72h表现的较为平均。因此,可根据生产方向选择不同的诱导方式进行处理。
For Gansu small tail han sheep of confinedness as test animal,which were used CIDR＋PMSG（test group I）,PG＋PMSG（test group II）,PG＋CIDR＋FSH（test group III）3different combinations for induced estrus synchronization experiment in non-breeding season.The results showed that three group＇s rate of estrus synchronization over 85%,the estrus rate of test group I is 94.95%in 72 h.It is significantly higher than others,but the cost is higher too.The test group II had lowest cost,and the estrus rate of test group III is average in 72 h.So we could choose best induced way according to the different production way.
