中文摘要:

      探索不同地区牛背最长肌的氨基酸、脂肪酸、微量元素等营养成分含量的差异。试验选取贵州、内蒙、新疆地区各6头36月龄左右公牛的牛背最长肌进行营养成分测定。结果表明：（1）内蒙地区牛背最长肌中甘氨酸、脯氨酸、丙氨酸等含量均显著高于贵州和新疆地区（P<0.05）；（2）内蒙地区牛背最长肌中硬脂酸、油酸等含量极显著高于贵州和新疆地区（P<0.01）；（3）贵州地区牛背最长肌中牛磺酸含量显著高于内蒙和新疆地区（P<0.05）；（4）新疆地区牛背最长肌中总胆固醇含量极显著低于贵州和内蒙地区（P<0.01)。综上所述，内蒙地区氨基酸、脂肪酸含量高；贵州地区牛磺酸含量高；新疆地区胆固醇含量低。

英文摘要:

      To explore the differences in the nutrient contents of amino acids, fatty acids, trace elements and other nutrients in the longest muscle of bovine back in different regions. The longest muscle of 6 bulls around 36 months old from Guizhou, Inner Mongolia and Xinjiang,were selected for nutrient content determination. The results showed that: (1) the contents of glycine, proline and alanine in the longest muscle of bovine back in Inner Mongolia region were significantly higher than those in Guizhou and Xinjiang regions (P<0.05); (2) the contents of stearic acid and oleic acid in the longest muscle of bovine back in the Inner Mongolia region were extremely significantly higher than those in Guizhou and Xinjiang regions (P<0.01); (3) the content of taurine in the longest muscle of bovine back in Guizhou region was significantly higher than that in the Inner Mongolia and Xinjiang regions (P<0.05); (4) the content of total cholesterol in the longest muscle of bovine back in the Xinjiang region was extremely significantly lower than that in Guizhou and Inner Mongolia regions (P<0.01). In summary, the content of amino acids and fatty acids was high in Inner Mongolia region, the content of taurine was high in Guizhou region and the content of cholesterol was low in Xinjiang region.
