【摘要】：为研究亚临床酮病奶牛的氧化应激状态及其对奶牛乳品质的影响,分别选取21头亚临床酮病奶牛和21头健康奶牛,通过尾静脉采集非抗凝血,用于氧化抗氧化指标的检测;同时收集新鲜乳样,用于乳成分的检测。结果表明,与健康奶牛相比,亚临床酮病奶牛的总抗氧化能力、谷胱甘肽过氧化物酶、乳蛋白和总固形物活性、血清葡萄糖显著或极显著降低(P0.05;P0.01),乳脂肪比、非酯化脂肪酸、β-羟基丁酸、丙二醛含量显著或极显著升高(P0.05;P0.01)。由此可见,亚临床酮病奶牛体内存在氧化应激,主要抗氧化酶活性降低,并且氧化应激状态显著高于健康奶牛,乳品质低于健康奶牛。
[Abstract]:In order to study the oxidative stress state of subclinical ketosis cows and its effect on milk quality of dairy cows, 21 subclinical ketosis cows and 21 healthy cows were selected to collect non-anticoagulant blood through tail vein for the detection of oxidative and antioxidant indexes. At the same time, fresh milk samples were collected for the detection of milk components. The results showed that compared with healthy cows, the total antioxidant capacity, glutathion peroxide, milk protein and total solid activity of subclinical ketosis cows and serum glucose were significantly or extremely significantly decreased (P0.05). The contents of milk fat ratio, non-esterified fatty acids, 尾-hydroxybutyric acid and malondialdehyde were significantly or extremely significantly increased (P 0.05 鈮，
