The widespread adoption of artificial insemination (AI) with stored boar semen has become an important production management tool in the Canadian swine industry.<\/p>\n
The current AI industry is built upon the use of liquid semen stored in extenders that provide commercially acceptable fertility rates for a period of several days. For much of the last two decades, common practice has been to store extended semen at 17\u00b0C and perform 2-3 intracervical inseminations\/estrus cycle using 1.5-3 billion sperm in a large volume (~70 ml). The swine industry has adopted production practices and the infrastructure required to produce, distribute and store these high quality semen doses from genetically superior boars at an economically viable cost.<\/p>\n
CRYOPRESERVED SEMEN<\/p>\n
In addition to the advantages of using liquid semen for AI, it also provides: the ability to plan inseminations, efficiencies in the import\/export of genetics, control of disease transmission, long-term genetic banking, genetic transfer between nucleus herds and can function as a backup in case of a disaster.<\/p>\n<\/div>\n
SEX SORTED SPERM<\/p>\n
A potential complementary technology for the use of frozen-thawed boar sperm and\/or low dose inseminations may be the use of sexed sperm. The benefits of sexed sperm to producers would be the production of more female piglets and a reduction in the number of male piglets that would need to be castrated.<\/p>\n
CONCLUSIONS<\/p>\n<\/div>\n<\/div>\n<\/div>\n
In the near future, adopting the use of cryopreserved and\/or sex-sorted sperm in combination with low dose insemination procedures, even in limited instances, may allow producers to exploit specific advantages they offer to their particular production circumstances.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
