摘要
为了研究不同处理方法对戴云山羊同期发情效果的影响,分别采用3种不同处理方法对戴云山羊空怀母羊进行同期发情处理,比较不同处理组母羊的发情率和受胎率。结果表明,试验1、2和试验3组的发情率分别为65.22、86.96和100。受胎率分别为56.52、65.22和91.30。其中试验3组的发情率显著高于试验1组(P<0.05),受胎率显著高于试验1组和试验2组。综合结果分析表明,试验3组的同期发情效果最优。
In order to study the effect of different treatment methods on estrus synchronization of Daiyun goat,three different treatment methods were used for estrus synchronization of non-pregnant ewes of Daiyun goat,and the estrus rate and conception rate of ewes in different treatment groups were compared.The results showed that the estrus rates of Daiyun goats second injected with PGF2α,ITC and PRID+PMSG+PGF2αwere 65.22%,86.96%and 100%respectively.The conception rate was 56.52%,65.22%and 91.30%respectively.The estrus rate of Daiyun goats treated with PRID+PMSG+PGF2αwas significantly higher than that of the second injection of PGF2αgroup(P<0.05),and the conception rate was significantly higher than that of the second injection of PGF2αgroup and the second injection of ITC group.The results showed that the treatment of PRID+PMSG+PGF2αhad the best estrus synchronization effect.
