摘要
为了观察冷冻稀释液中添加不同浓度的抗氧化剂谷胱甘肽(GSH)、绿茶多酚(GTPs)、维生素E(VE)和超氧化物歧化酶(SOD)对金华猪精液冷冻保存效果的影响,分别在冷冻稀释液中添加0.125、0.25、0.5 mmol.L-1的GSH,10、15、20 mmol.L-1的GTPs,1、2、4 mg.mL-1的VE和1 000、2 000、4 000 I U的SOD,采集活率较高的金华猪精液,用上述含抗氧化剂的冷冻稀释液稀释后进行冷冻保存,分别检测4个处理组精子4℃平衡后的活率和解冻后精子活率、质膜完整性、顶体完整率。结果表明,在金华猪精液的冷冻稀释液中分别添加15 mmol.L-1GTPs、2 mg.mL-1VE、4 000 I U SOD可显著提高猪精子4℃平衡后的活率、解冻后精子活率和质膜完整率(P<0.05)。
To compare the effects of different antioxidant concentrations of glutathione (GSH), green tea polyphenols (GTPs), vitamin E (VE) and superoxide dismutase (SOD) on cryopreservation of Jinhua boar sperm, freezing extenders were supplemented with the GSH (0, 125, 0.25 and 0.5 mmol·L^-1 ), GTPs (10, 15 and 20 mmol·L^-1), VE(1, 2 and 4 mg·mL-1) and SOD (1000, 2000 and 4000 IU), respectively. The boar sperms were collected and frozen with extenders containing above antioxidants. Sperm motility after 4 ℃cooling, sperm motility, membrane integrity and acrosome integrity after thawing were examined in four treatment groups. The results show that sperm motility after 4℃ cooling, sperm motility and membrane integrity after thawing were increased significantly by supplemented boar freezing extenders with 15 mmol·L^-1 GTPs, 2mmol·L^-1 VE or 4 000 IU SOD, respectively (P〈 0. 05).
