Artificial insemination has achieved a dynamic increase in genetic progress, and this is due to the improvement of sperm preservation technology. In recent years, a lot of attention has been paid to optimizing bull sperm storage environment and objectifying methods of sperm quality analysis. This review presents bull sperm preservation methods and ways to modify their storage environment. The main purpose of sperm preparation for artificial insemination is to obtain sperm with a high percentage of viable, motile sperm with normal morphology and low DNA fragmentation rates. Currently conducted experiments indicate the possibility of improving the quality of insemination doses produced using various components enriching common diluents. However, despite extensive research, no better results have been achieved than obtaining insemination doses with sperm viability that exceeds just over 60%. Obtaining a very good quality of frozen semen seems to be still unachievable today.

环境优化对公牛精子细胞储存的作用。

人工授精实现了基因进步的动态增长,这得益于精子保存技术的进步。近年来,公牛精子储存环境的优化和精子质量分析的客观化方法得到了广泛的关注。本综述介绍了公牛精子保存方法和修改其储存环境的方法。用于人工授精的精子制备的主要目的是获得具有正常形态和低 DNA 断裂率的高比例的活精子。目前进行的实验表明,使用各种富含普通稀释剂的成分可以提高所产生的授精剂量的质量。然而,尽管进行了广泛的研究,没有比在精子活力超过 60% 的情况下获得授精剂量更好的结果了。获得质量非常好的冷冻精液今天似乎仍然无法实现。
