Abstract: The wide application of artificial insemination technology has played a positive role in promoting the sound and rapid development of the pig industry. Due to the fast development of the modern express industry and the maturity of estrus synchronization technology in swine, artificial insemination can be performed with the liquid-preserved semen globally. Compared to the cryopreservation methods, normal temperature preservation methods have some irreplaceable advantages. Improving the utilization rate of genetic resources of improved boars is closely associated with the normal temperature preservation technology of their semen. The liquid preservation technology of boar semen at normal temperature is reviewed from the aspects of temperature, season and additives in semen extenders.

Key words: boar semen, normal temperature preservation, influencing factors, semen quality
