摘　　要：试验通过对库布齐蒙古牛与西门塔尔牛肉品质部分指标及肌肉矿物质含量进行分析测定,研究库布齐蒙古牛的肉品质特性。选择库布齐蒙古牛与西门塔尔牛各6头,采集背最长肌进行样品分析。结果表明:蒙古牛肉色泽深红,红度a*、黄度b*、系水率、熟肉率、剪切力均高于西门塔尔牛,且均呈显著性差异(P<0.05),而失水率及pH显著低于西门塔尔牛(P<0.05);蒙古牛肌肉微量元素Cr、Cu、Fe、Mn、Se、Zn含量均显著高于西门塔尔牛(P<0.05),肌肉中P和I含量均显著低于西门塔尔牛(P<0.05),其他元素含量差异不显著(P>0.05)。说明库布齐蒙古牛肉口感、多汁性及色度方面较优,肌肉中大部分矿物质元素含量高于西门塔尔牛,肉品质较高。The assay was aimed to explore the beef quality and characteristics of Mongolia beef by comparative on beef quality and mineral elements of Mongolia beef and Simmental cattle.6 Mongolia beef and 6Simmental cattle were chosen to collect the longissimus for analysis.The results showed that the color of Mongolia beef was wine-colored.The a＊value,b＊value,water holding ratio,cooked meat rate and shear force of Mongolia beef were significantly higher than Simmental cattle（P〈0.05）,and the drip loss rate and pH were significantly lower than Simmental cattle（P〈0.05）.The amount of Cr,Cu,Fe,Mn,Se and Zn were significantly higher in longissimus in Mongolia beef comparing to Simmental cattle（P〈0.05）,while the amount of P and I were significantly lower（P〈0.05）,and other elements contents were no significant difference（P〉0.05）.It suggested that the taste,juiciness and chromaticity of Kubuqi Mongolia beef were better and it had richer particle minerals than Simmental cattle,indicating that Mongolia beef had higher meat quality.
