摘要

Two field experiments were conducted to investigate the amount of variation between rams, and between ejaculates within rams, in the fertility of frozen-thawed semen used for cervical insemination. Individual ejaculates from seven Merino rams were frozen and used to cervically inseminate Merino ewes at a synchronized oestrus at two sites. In Experiment 1 (N = 491), pregnancy rates (determined 70–80 days after insemination) for individual rams ranged from 1.8 to 11.9%. Individual ejaculates produced pregnancy rates between 0 and 21.4%. Overall conception rate was 6.5%. No significant differences were detected. Pregnancy rates for the same rams in Experiment 2 (N = 449) varied from 10.3 to 32.6% (P P P

进行了两次大田实验来研究公羊在公羊内射精之间在用于宫颈授精的冷冻 - 解冻精液的生育率之间的变化量。来自七只美利奴公羊的个别射精被冻结，并用于在两个地点同步发情的情况下对美利奴母羊进行子宫颈授精。在实验1（N \x3d 491）中，每只公羊的怀孕率（受精后70-80天确定）介于1.8至11.9％之间。个别射精产生0至21.4％的怀孕率。总体受孕率为6.5％。没有发现显着差异。实验2（N \x3d 449）的同一公羊的怀孕率从10.3到32.6％不等（P P P
