猪精液冷冻保护剂的研究进展

Research Progress on Boar Semen Cryoprotectants

冷冻保护剂是猪精液冷冻稀释液的关键组分,能有效缓解冷冻及复苏过程中对精子造成的损伤,是决定猪精液冷冻效果的重要因素。因此,研究新型冷冻保护剂,是提高猪精液冷冻保存效果的有力措施。本文就近年来国内外抗氧化性物质、糖类等新型冷冻保护剂的研究与应用进展进行综述,以期进一步提高猪冷冻精液的质量,发挥良种的种用价值。

As an important additive of cryopreservation dilution,cryoprotectants can remit the damage to the sperm caused by freezing and recovery.Cryoprotectants is the key factor influencing the effectiveness of freezing semen,and therefore,researching new cryoprotectants is a good measure to maximize the impact of freezing semen.The research advancement of new cryoprotectants such as antioxidant and saccharides are reviewed in this paper.
