摘要 本试验在绒山羊冷冻精液稀释液中分别添加0 mmol/L、 2.5 mmol/L、 5 mmol/L、 7.5 mmol/L和10 mmol/L等5个梯度的半胱氨酸,确定半胱氨酸的最佳添加浓度,以优化绒山羊冷冻稀释液配方。试验结果表明,添加7.5 mmol/L半胱氨酸组精子的活率、顶体完整率和生存指数均高于其它试验组(P <0.05),而畸形率低于其它试验组(P <0.05);在脂质过氧化反应和抗氧化酶活性方面,该试验组MDA浓度低于其它试验组(P <0.05),而CAT活性高于其它试验组(P <0.05)。总之,在绒山羊冷冻稀释液中添加7.5 mmol/L半胱氨酸,精子冷冻解冻后,能起到很好的保护精子的作用。
