| 摘 要： | 常规子宫颈人工授精(cervical artificial insemination，CAI)技术输精量大，存在浪费和不经济的问题，尤其在使用高附加值的精液产品时更为突出。近年来，一种高效利用猪精液的深部输精技术得到了研究和应用，这种技术与定时输精技术相结合，直接将精液输送至子宫体、子宫角和输卵管内，减少了每头母猪受孕所需精子数目，大幅度提高了良种公猪的利用价值，有助于实现冷冻保存精液和性控精液在养猪生产上的商业化应用。作者概述了猪人工授精中3种深部输精技术在液态保存、冷冻保存和性控精液上的研究和应用情况。无论实施哪种输精技术，公猪繁殖力、精子活力、母猪的饲养管理、输精时间和人工授精技术操作的规范性都是提高受胎率必须要考虑的因素。

| Abstract: | Current cervical artificial insemination（CAI）procedure involving deposition of excessive sperm numbers is uneconomical for pig industry that is more outstanding in the use of high value-added semen product. In recent years, a deep insemination procedures in combination with fixed-time AI that was greatly developed and applied have shown to be beneficial for reducing the number of sperm required per pregnant sow, thus allowing the best use of valuable boars and, ultimately, the commercial integration of frozen-thawed and sexed sperm. This article provides an overview of the research development and application of the deep insemination procedure for liquid-stored, frozen-thawed and sexed sperm. Variables such as boar fertility, viable sperm rate, sow management, timing of semen delivery and insemination technology should be carefully considered to improving the fertility outcome. |
