| 用RPE简易冷冻器快速冷冻6～7日龄萨能奶山羊胚胎.将在液氮中冻存12～819d的胚胎用液氮雌经汽车或火车运至外地,并把解冻后的73枚胚胎移植给38只当地山羊。受体妊娠率为60.5%,移植胚产羔率为39.7%.胚胎冻存12～21,195～265,320～450和687～891d时,移植产羔率分别为38.5%,45.8%,41.7%和25.。%.各冻存期间差异不显著(P>0.05). |

| Abstract: |
| Embryos from superovulated Saanen dairy goats on days 6一7 (mating
day=day 0)were quiekly frozen in a simple RPE freezer.After being frozen for 12～819
days,apart of embryos was transported by car or train to other places of the country
using a jar with LN2.After thawing,73 embryos were transferred into 38 recipients of
indigenous goats.Pregnant rate of recipients was 60.5% (23/28).Kidding rate of the
transferred embryos was 39.7%(29/73).After being frozen for 12～21,198～125,320～480 and 687～819 days,no significant difference (P>0.05) was found in kidding
rates of transferred embryos which had been frozen for different duration. |
