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.<\/jats:p>","DOI":"10.1111\/j.1439-0531.2006.00768.x","type":"journal-article","created":{"date-parts":[[2006,9,20]],"date-time":"2006-09-20T09:05:25Z","timestamp":1158743125000},"page":"43-53","source":"Crossref","is-referenced-by-count":63,"title":["Challenges
