摘    要:为建立新疆巴州肉用细毛羊基地,2000-2004年在新疆巴州种畜场以胚胎移植技术为主要扩繁手段,用引进的纯种肉用细毛羊实施超排胚移6个批次,累计处理供体71只(次)获可用胚胎504枚,均只获可用胚胎7.1枚,移植受体489只,早检妊娠率56.0%,产羔母羊231只,产羔母羊占移植受体数47.2%。四年内通过超排胚移和人工授精配种繁殖方法,共生产了肉用细毛羊426只,其中胚胎移植生产羔羊241只。四年中淘汰不合格个体24只,对外出售种公羊66只,至2005年年末肉用细毛羊纯繁群的存栏量为260只,是初始数26只的10倍,其中通过胚胎移植手段获得的数量占总增长数量的56.75%。

关 键 词:超排胚移  肉用细毛羊  扩繁

Abstract:In order to build up the Xinjiang Bazhuo mutton type fine-wool sheep base,embryo transplanting technology was used as main method to expand population of the sheep.After 6 times multiple Ovulation,A total of 504 embryos were obtained from 71 introduced pure breed mutton type fine-wool sheep,in which 7.1 useable embryos was obtained for each female animal in each operation time.A total of 489 acceptors were transplanted with these embryos,after earlier pregnancy checking,the pregnancy rate is 56.0%,231 lambs were obtained and the lambing rate was 74.2%.426 mutton type fine-wool sheep lambs,in which 241 lambs were obtained with embryos transplantation technology,were obtained in all during 4 years with the Multiple Ovulation and Artificial Insemination technology.24 disqualified sheep were eliminated and 66 stud male sheep was sold.Till the end of 2005,amount of livestock on hand of mutton type fine-wool sheep was 260,it was 26 folds of the original number and 56.7% sheep were obtained from embryo transplantation technology.
Keywords:MOET  mutton type fine-wool sheep  breeding and expanding the population
