摘要: 本实验选择12头体重相近、健康无疾病的延(边)黄牛(公牛),研究了日粮VE水平对熟化过程中牛肉肉色和抗氧化酶活性的影响。将试牛随机分为对照组和添加500、1000和2000IU的VE组。实验结果表明,在熟化的第7d,添加VE组的红色度(CIE a*)显著高于对照组(p<0.05),并且可明显提高肌肉内VE含量和组织抗氧化酶(GPx、CTA)活性,各添加组间,1000IU VE添加组效果最佳。

Abstract: Selecting 12 healthy Yanbian cattle(bulls) with weight close as study objects,effects of different levels of vitamin E appended in diet on color properties of beef and activities of antioxidant enzymes during maturation were studied. The cattle were divided into control group and experimental groups,in which the levels of vitamin E appended in diet of the cattle were 500,1000 and 2000 IU respectively. The results showed that on curing 7thd,red chromaticity(CIE a) of the experimental groups is higher than that of the control(p<0.05) ,and the vitamin E content and antioxidase(GPx and CTA) activity are enhanced obviously. Among the experimental groups,the effect of 1000 IU vitamin E group is the best.

Key words: vitamin E, beef color, antioxidant enzyme, maturation
