Abstract

The impact of freezing and chilling on the semen of FUNAAB Alpha (Normal feather) chickens was examined in this study. Pooled semen collected from ten FUNAAB Alpha (Normal feather) chicken were diluted with Tris –based extender. Diluted semen was divided into two fraction, the first fraction was subjected to chilling at 4oC and the second fraction was subjected to freezing at 1oC for 24hrs. Thereafter semen were evaluated for viability, functional integrity and oxidative stress (Malondialdehyde concentrations MDA and seminal leukocytes). The result showed a consistent variation in the viability and functional integrity. However, Sperm motility and livability preserved at 4oC was significantly higher (p<0.05) than those preserved at 1oC. Abnormal sperm (head, mid piece and tail) recorded for those preserved at 4oC was significantly lower (p<0.05) than those preserved at 1oC. The findings indicate that sperm viability, functional integrities and oxidative stress parameters of FUNAAB alpha (Normal feather) were better preserved by chilling compared to freezing method.

冷冻和冷藏对 funaab alpha（正常羽毛）鸡精子存活率和氧化特性影响的比较研究

本研究考察了冷冻和冷藏对 FUNAAB Alpha（正常羽毛）鸡精液的影响。从 10 只 FUNAAB Alpha（正常羽毛）鸡身上收集的精液用三羟甲基氨基甲烷基扩展剂稀释。稀释后的精液分为两部分，第一部分在 4oC 下冷冻，第二部分在 1oC 下冷冻 24 小时。之后，对精液的活力、功能完整性和氧化应激（丙二醛浓度 MDA 和精液白细胞）进行评估。结果表明，精子活力和功能完整性的变化是一致的。不过，在 4oC 温度下保存的精子活力和存活率明显高于在 1oC 温度下保存的精子（p<0.05）。在 4oC 温度下保存的精子（头部、中段和尾部）的畸形率明显低于在 1oC 温度下保存的精子（p<0.05）。研究结果表明，与冷冻法相比，冷冻法能更好地保存 FUNAAB alpha（正常羽毛）的精子存活率、功能完整性和氧化应激参数。
