影响猪精液液态常温保存的主要因素

人工授精技术的广泛应用,对生猪产业又好又快的发展起到了积极作用。由于现代快递业的飞速发展和猪同期发情技术的成熟,液态保存的精液可以在全球范围实施人工授精。与冷冻保存相比,常温保存有着无可替代的优势,提高良种公猪遗传资源的利用率与猪精液的常温保存技术密不可分。从温度、季节、稀释液添加物质等方面对猪精液液态常温保存进行了综述。

Main Factors Influencing Liquid Preservation Quality of Boar Semen at Normal Temperature

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.
