摘 要：
通过冷冻胚胎移植技术,2007年和2008年前后分2批在鄂尔多斯细毛羊种羊场实施纯种澳美型细毛羊冷冻胚胎移植,共有371只(2007年266只,2008年105只)受体羊做了冷冻胚胎移植,共生产澳美型细毛羊羔羊106只(2007年70只,2008年36只)。其中公羔60只,母羔46只;受胎率分别为26.32%和37.14%;羔羊初生重为公羔(4.73±0.41)kg/只、母羔(4.54±0.43)kg/只和公羔(4.60±0.68)kg/只、母羔(4.45±0.55)kg/只。经过调查鉴定,用冷冻胚移植技术获得羔羊106只,经培养共获得纯种澳美型细毛羊106只,补充了优质澳美型细毛羊种羊的数量,大大增加了纯种澳美型细毛羊的种源数量、节省了引种费用、缩短了鄂尔多斯细毛羊改良世代间隔和选育提高周期,起到了加速优良种畜繁殖速度、迅速扩大种源的科技效应。

摘 要：
Using the frozen embryo transfer technology, frozen embryo transfer was made on two batches of 371 Australia Merino fine-wool sheep receptors in 2007(266 sheep) and 2008 (105 sheep). And 106 lambs of Australia Merino fine-wool sheep were produced (70 in 2007 and 36 in 2008), which included 60 male lambs and 46 female lambs. The conception rate of male and female lambs were 26.32% and 37.14% respectively. And the birth weight of male and female lambs were (4.73 ± 0.41) kg and (4.54 ± 0.43) kg, (4.60 ± 0.68) kg and (4.45 ± 0.55) kg respectively. After investigation and identification,it was found that 106 lambs were obtained by using frozen embryo transfer technology and 106 pure Australia Merino fine-wool sheep were cultured. Thus research supplied the number of high-quality Australia Merino fine-wool sheep, greatly increased the number of pure Australia Merino fine-wool sheep, saved the introduction cost, shorten the generation intervals and breeding cycle of Australia Merino fine-wool sheep, which accelerated the reproductive speed of excellent breeders and extended rapidly the scientific and technological effects of seed sources.
