摘要
为评价繁殖季节胚胎移植技术在规模化羊场的应用效果,对萨福克羊和杜泊羊2个品种在繁殖季节超数排卵和胚胎移植情况进行了统计分析。结果表明,试验羊经过同期发情、超数排卵后,黑头杜泊羊生产可用胚胎数极显著高于萨福克羊(P<0.01),但其不可用胚胎占比较高(22.72%);秋季胚胎移植母羊受胎率极显著高于冬季(P<0.01),2056只受体母羊的平均受胎率达59.19%。综上所述,黑头杜泊羊超数排卵后的胚胎生产量高于萨福克羊,但可用胚胎比例还有待于提高,同时,秋季胚胎移植可提高母羊受胎率。
In order to evaluate and improve the application effect of embryo transfer technology in breeding season in large-scale sheep farms,the superovulation and embryo transfer results of Suffolk sheep and Dorper sheep in breeding season were analyzed in this study.The results showed that the number of available embryos produced by Black-headed Dorper sheep was significantly higher than that of Suffolk sheep after synchronization and superovulation(P<0.01),but the proportion of unavailable embryos produced by Black-headed Dorper sheep was higher,which was 22.72%.The pregnancy rate of embryo transfer ewes in autumn was significantly higher than that in winter(P<0.01).The average pregnancy rate of 2056 recipient ewes was 59.19%.In summary,Black-headed Dorper sheep have better embryo production than Suffolk sheep after superovulation,but the proportion of available embryos needs to be improved.Embryo transfer in autumn can improve the conception rate of ewes.
