摘要
为了阐明奶牛分娩前抗氧化系统变化规律与胎衣不下的关系,以荷斯坦奶牛为研究对象,筛选165头妊娠期各项指标正常的奶牛,于分娩前1周静脉采血及测定血浆中谷胱甘肽过氧化物酶(GPX)、过氧化氢酶(CAT)含量,并按照胎衣不下的标准(产后胎衣12h内不能正常排出)进行分组对比分析。结果表明:筛选的165头奶牛有19头在产后表现为胎衣不下,发病率为11.5%;胎衣不下奶牛血浆GPX活性(104.00±80.19U/mL)显著低于正常奶牛(134.82±71.34U/mL,P<0.05),CAT活性(1.44±1.08U/mL)也低于正常奶牛(1.63±1.74U/mL,P>0.05)。说明奶牛血浆中GPX、CAT活性与产后胎衣不下存在必然联系。
In order to study the relationship between the placental retention and change in antioxidant enzyme activities before parturition of cow,165 Holstein cows with normal indices at gestation period were selected and blood samples collected from veins,and the activities of glutathione peroxidase（GPX） and catalase（CAT） in blood plasma were determined before one week of parturition and compared in different placental retention groups according to the standards（abnormal elimination of placenta in 12 hours after parturition）.The results showed that out of 165 cows,19 showed placental retention with 11.5% incidence.The activity of GPX and catalase in cows with placental retention was significantly lower than that in normal cows.The results showed the possibilities of relation between the activities of GPX and CAT and the occurrence of placental retention after parturition in cows.
