山羊精液冷冻保存稀释液添加剂研究进展

Research Progress on Extender Additives for Goat Semen Cryopreservation

精液冷冻保存技术是山羊繁育体系的重要组成部分,可以有效保存优质种质资源并加速山羊育种工作进程。山羊精子在冷冻过程中会受到氧化应激、冷应激等不利因素的损伤,导致山羊精子解冻后质量和人工授精受胎率较低,大大限制了山羊冻精的应用。因此,本文综述了近年来在山羊冷冻保存稀释液中添加抗氧化剂、糖类、脂肪酸等添加剂对山羊精子解冻后质量的影响,以期为山羊冷冻精液研究提供理论参考。

Cryopreservation techniques for goat semen are an important part of the goat breeding system, which can effectively preserve high-quality germplasm resources and accelerating the process of goat breeding efforts. However, goat sperm will be damaged by oxidative stress, cold stress and other adverse factors during freezing, resulting in low quality of goat sperm after thawing and low conception rate of artificial insemination, which greatly limits the application of frozen goat semen. Therefore, in this review, we investigated the effects of antioxidants, sugars, fatty acids, and other additives added to goat cryopreservation extender on post thaw sperm quality in the hope of providing a theoretical reference for studies on frozen goat semen.
