Semen extended in a liquid state, together with conventional artificial insemination (AI), is the sole sperm technology used by the pig industry. Sperm technologies known for many years, such as cryopreservation, and others developed during recent years, such as sperm sexing, have not yet been integrated into commercial use. Moreover, there has recently been an explosion of new technologies, such as sperm mediated gene transfer or encapsulated spermatozoa which need additional supportive techniques before they can be economically applied to pig breeding. The speed with which the aforementioned sperm technologies are accepted and utilized by the pig industry depends on the availability of efficient insemination procedures. Therefore, AI is entering a new dimension where it will be converted into a tool for the efficient application of current and new sperm technologies. Some new insemination procedures have been recently developed. This review examines the suitability of available insemination procedures for the efficient application of current, emergent and future sperm technology to the pig industry.
液态保存的精液，连同传统的人工授精（AI），是养猪业唯一使用的精子技术。已为人所知多年的精子技术，如冷冻保存，以及近年来开发的其他技术，如精子性别分选，尚未整合到商业应用中。此外，最近新技术激增，如精子介导的基因转移或包封精子，在它们能够经济地应用于猪育种之前，还需要额外的支持技术。上述精子技术被养猪业接受和利用的速度取决于高效授精程序的可用性。因此，人工授精正在进入一个新的阶段，它将被转化为一种有效应用当前和新精子技术的工具。最近已经开发了一些新的授精程序。本综述探讨了现有授精程序对于当前、新兴和未来精子技术在养猪业中高效应用的适用性。
