不同品种、胎次对牦牛乳中超氧化物歧化酶活性的影响

摘要

Each 30 yak milk samples were collected from Gannan County and Tianjun County,and 90 yak milk samples were collected from three different yak farms in Tianzhu County,in order to determine and compare the SOD activity to provide a theoretical basis for further devdopment and utilization of enzyme activity of yak milk.The result shows that no significant differences among the SOD activity in three yak milks from Tianzhu County,Gannan County and Tianjun County,while there was no outstanding difference among the SOD activity in three yak milks from Tianzhu County also.In all,the variety has no obvious effect on the SOD activity in yak milk,so did parity.%对采自青海天峻、甘肃甘南各30份牦牛乳样以及天祝抓喜秀龙乡红疙瘩村、岱乾村和碳山岭镇四台沟村3个天祝白牦牛主产区的90份乳样,进行超氧化物歧化酶活力检测分析,比较青海高山牦牛与甘肃甘南高原牦牛、甘肃天祝白牦牛乳中SOD活性,为牦牛乳中活性物质的开发利用提供理论基础.结果表明:3个品种牦牛乳的SOD活性存在一定差异,但是差异性不显著(P＞0.05);天祝白牦牛3个牧区的牦牛乳中SOD活性差异不显著(P＞0.05);不同胎次条件下牦牛乳中SOD活性差异不显著(P＞0.05).即品种、胎次对牦牛乳中SOD活性影响均不显著.
