Retention of high motility of horse spermatozoa preserved at 4 degrees C was improved by a semen extender. Raw semen preserved for 2 to 8 hr at 4 degrees C gave an average conception rate of 67-3% but preservation for 1 to 2 days gave an extremely low conception rate. The conception rate from deep-frozen semen during 8 years was 56-3%.
一种精液稀释剂提高了保存在4摄氏度下的马精子的高活力保留率。在4摄氏度下保存2至8小时的新鲜精液平均受胎率为67.3%，但保存1至2天则受胎率极低。8年间冷冻精液的受胎率为56.3%。
