摘  要:
自1975年开始此项研究,五年来,着重对绵羊冷冻精液稀释液的保护性能进行研究;同时还进行了精液冻前处理、冷冻和解冻方法等方面的研究。16种稀释液进行了受胎试验。共授精母羊2983头,产羔970头,情期受胎率平均为32.5%(13.7~58.9%)。其中各年最佳组合的情期受胎率分别为43.3%(26/60,1975),51.3%(39/76,1976),58.9%(43/73,1977)和53.4%(47/88,1979)和57.1%(48/84,1979)。

摘  要:
We have begun the present studies since 1975,and have laid special emphasis on the studies of the protective function of the extenders for deepfreezing ram semen.At the same time,experiments on the treat- ment of sperms before freezing and the freezing and thawing methods were also conducted. The semen diluted with 16 extenders was frozen and used for inse- mination experiments of 2,983 ewes,from which 970 have lambed.The overall average conception rate after the first oestrus was 32.5%(from 13.7 to 58.9%).The conception rates for the best groups in separate years are as follows 43.3%(26/60,1975),51.3%(39/76,1976),58.9% (43/73,1977),53.4%(47/88,1979)and 57.1%(48/84,1979).
