中文摘要:

      产肉性能是肉牛最为重要的经济性状指标，新疆夏洛莱肉牛作为一种肉质优良、生长迅速的品种，在新疆塔额地区被广泛养殖。为了研究新疆夏洛莱牛肉的营养特征，选取了新疆兵团第九师165团养殖的25 头新疆夏洛莱肉牛同一部位的牛肉进行营养成分检测，并与文献报道的西门塔尔、安格斯等品种的牛肉营养数据进行了比较分析。结果显示，新疆夏洛莱牛肉的水分、蛋白质、脂肪和灰分含量均与安格斯、西门塔尔杂交后代牛肉没有显著差异；夏洛莱牛肉的氨基酸总量为16.94～18.78 g/hg，低于安格斯牛肉（18.10～19.12 g/hg），必需氨基酸总量也低于安格斯牛肉；饱和脂肪酸含量为55.46%～62.44%，远高于安格斯牛肉的脂肪酸含量（43.16%～49.00%），其中单不饱和脂肪酸含量（23.69%～37.61%）与安格斯牛肉（25.95%～37.91%）接近。通过对新疆夏洛莱牛肉主要营养成分、矿物质、氨基酸、脂肪酸等营养指标的测定与评价，认为新疆夏洛莱牛肉主要营养成分及氨基酸含量丰富，可在新疆肉牛品种选择及肉牛杂交改良中进一步开发利用。

英文摘要:

      Meat production performance is the most important economic trait index of beef cattle.As a breed with excellent meat quality and rapid growth,Xinjiang Charolais beef cattle is widely raised in Ta’eh region of Xinjiang.In order to study the nutritional characteristics of Xinjiang Charolais beef,the nutritional composition of 25 Xinjiang Charolais beef raised in the same part of the 165 Regiment of the 9th Division of Xinjiang Corps was detected,and the nutritional data of Simmental and Angus beef were compared with those reported in the literature.The results showed that the moisture,protein,fat and ash contents of Xinjiang Charolais beef were not significantly different from those of Angus and Simmental crossbred beef.The total amino acid content of Charolais beef was 16.94-18.78 g/hg,lower than that of Angus beef (18.10-19.12 g/hg),and the total essential amino acid content was also lower than that of Angus beef.The content of saturated fatty acids was 55.46% to 62.44%,which was much higher than that of Angus beef (43.16% to 49.00%),and the content of monounsaturated fatty acids (23.69% to 37.61%) was close to that of Angus beef (25.95% to 37.91%).Through the determination and evaluation of the main nutrients,minerals,amino acids and fatty acids of Xinjiang Charolais beef,it was concluded that the main nutrients and amino acids of Xinjiang Charolais beef were rich,which could be used for the selection of Xinjiang beef breeds and further development and utilization in the crossbreeding of beef cattle.
