摘要
利用配种后未受胎母羊及幼龄母羊做供体,用本程序进行德国美利奴肉用羊超排移植,并分析供体状态与超排效果的相关关系,结果：①超排处理后得到：供体均只黄体数10.8个,均只采卵数8.1枚,均只可用胚7.55枚;受体移植妊娠率61.6%。②超排后均只卵巢黄体数,成年供体显著高于青年、幼年供体,成年（3~6岁）、20月龄与7月龄供体卵巢黄体分别为15个、9.86个与7个,差异显著。③超排后幼龄与青年供体其胚胎发育速度显著高于成年供体,不同龄供体分获各胚龄胚胎比例为：7月龄供体＂M与EM＂75%、＂CBL、BL与EXBL＂25%,20月龄供体＂M与EM＂76.5%、＂CBL、BL与EXBL＂23.5%,成年供体＂M与EM＂100%、＂CBL、BL与EXBL＂0%,差异显著。④小剂量FSH是否预注,超排效果差异显著：预注的超排后卵巢黄体成年供体平均15个、20月龄供体平均13个,未预注的卵巢黄体成年供体平均7.5个、20月龄供体9.64个。
Not become pregnant after mating ewes and young sheep to do for the body,using the procedures Germany Merino meat sheep superovulation transplantation,and analysis of donor states and the correlationbetween superovulation results： ①obtained after superovulation： Donor are only a few luteal 10.8,the number of eggs were collected only 8.1,are only available embryo 7.55;receptor pregnancy rate 61.6%.② aftersuperovulation were only a few ovarian corpus luteum of adult donors were significantly higher than young people,young donor age（3-6 years）,20 months and 7 months old donor corpus luteum were 15,9.86 and 7,significant difference.③After the young and young superovulated donor of their embryonic development was significantly higher than the adult rate for the body,not divided by age of donor embryos of various embryonicratio： 7 months old donor ＂M and EM＂ 75%,＂CBL,BL and EXBL＂25%,20months for the body＂ M and EM ＂76.5%,＂CBL,BL and EXBL＂23.5%,adult donor＂M and EM ＂100%,＂CBL,BL and EXBL ＂0% the differenceis significant.④small dose of FSH is pre-injection,the effect of superovulation significantly different： pre-registrations after Superovulation corpus luteum of adult donor average of 15 and 20 months for the body of anaverage of 13,without pre-injection of the corpus luteum of adult donor,an average of 7.5 20 month old donor 9.64.
