摘 要：
为了缩短春季产后母羊发情间隔,实现羊的两年三产或三年五产,促进青年母羊的正常发情配种,分3个批次进行了同期发情试验,比较了孕酮栓来源和诱导发情方法两个处理因素对产后两个月左右的小尾寒羊和青年母羊诱导发情效果的影响。结果表明,新西兰孕酮栓+PMSG组72 h产后2月龄母羊发情率(93.75%)和情期受胎率(100.00%)最高,其次为中国孕酮栓组(85.19%,86.96%)和中国孕酮栓+PMSG组(81.48%,90.91%)。澳大利亚孕酮栓组(13 d)产后母羊发情效果好于中国孕酮栓(13 d)+PMSG组,但情期受胎率(87.88%)低于中国孕酮栓组(100.00%),从发情率和受胎率方面考虑,中国孕酮栓(13 d)+PMSG组发情率和受胎率较好。中国孕酮栓(12 d)+PMSG组72 h内青年母羊发情率最高(100.00%),其次为新西兰孕酮栓组(52.00%)和中国孕酮栓(13 d)+PMSG组(51.22%),而情期受胎率从高到低为中国孕酮栓(13 d)+PMSG组(90.48%)、新西兰孕酮栓组(84.62%)、中国孕酮栓(12 d)+PMSG组(69.57%)。使用中国孕酮栓(13 d)+PMSG组诱导产后2月龄母羊发情率和受胎率最好,中国孕酮栓(12 d)+PMSG组诱导青年母羊发情率最高。

摘 要：
In order to shorten the estrus interval of the spring postpartum ewes, to achieve two years of three producing sheep or three years five,and promote young ewe normal estrus, the estrus synchronization test was divided into 3 batches,compared estrus induction effect from two factors of different sources of CIDR and treatments on Small-taied Han sheep and the young ewes. The results showed that estrus rate(93.75%) and pregnancy rate(100.00%) in the group of the New Zealand CIDR+PMSG were higher than the other groups, followed by domestic CIDR group(85.19%, 86.96%) and domestic CIDR+PMSG group(81.48%, 90.91%). The Australia CIDR(13 d) group on postpartum ewes is better than domestic CIDR(13 d)group, but the conception rate(87.88%) lower than the domestic group(100.00%), considering from the aspects of estrus and pregnancy rate,domestic CIDR(13 d)+PMSG group was better. domestic CIDR(12 d)+PMSG group of young ewes estrus rate was the highest(100.00%) in 72 h, followed by the New Zealand CIDR group(52.00%) and the domestic CIDR(13 d)+PMSG group(51.22%),while the interestrus conception rate from high to low are the domestic CIDR(13 d)+PMSG group(90.48%),the New Zealand CIDR group(84.62%) and domestic CIDR(12 d)+PMSG group(69.75%). It was concluded that the best estrus and conception rate of postpartum two months ewes is the used of domestic CIDR(13 d)+PMSG group, the domestic CIDR(12 d)+PMSG group induced by young ewes estrus rate was the highest.
