摘　　要：[目的]阿拉善牛是蒙古牛的一个重要群体,是我国宝贵的肉牛遗传资源。为了解阿拉善牛生长和肉质特性。[方法]本研究对47头阿拉善牛的生长指标进行测定,同时对16头阿拉善牛和13头对照牛的背部最长肌的37种脂肪酸进行分析。[结果]表明:各年龄段阿拉善牛的体尺指标均较低;阿拉善牛背部最长肌共检测到23种脂肪酸;阿拉善牛的二十碳五烯酸(EPA)极显著高于安格斯牛、夏洛莱牛和日本黑毛和牛(P<0.01);ω-3脂肪酸极显著高于日本黑毛和牛(P<0.01),显著高于安格斯牛和夏洛莱牛(P<0.05);ω-6脂肪酸极显著高于夏洛莱牛(P<0.01)。[结论]阿拉善牛富含优质的不饱和脂肪酸,可以作为我国开发优质牛肉产品的宝贵肉牛品种资源。[Objective]Alxa cattle,which is an important population of Mongolia Cattle,is a valuable genetic resource of beef cattle in China.In order to understand the growth and meat quality characteristics of Alxa cattle.[Methods]The body size indexes of 47 Alxa cattle were measured,and 37 fatty acids in longissimus dorsi muscle of 16 Alxa cattle and 13 control cattle were analyzed.[Results]The results showed that the body size index of Alxa cattle at all ages were low.23 fatty acids were detected in longissimus dorsi muscle of Alxa cattle.Eicosapentaenoic acid(EPA)of Alxa cattle was significantly higher than that of Angus,Charolais and Japanese Black cattle(P<0.01);ω-3 fatty acids were significantly higher than those in Japanese Black cattle(P<0.01)and Angus and Charolais cattle(P<0.05);ω-6 fatty acids were significantly higher than those in Charolais(P<0.01).[Conclusion]Alxa cattle is rich in high-quality unsaturated fatty acids,which can be used as a valuable beef resource to develop high-quality beef products in China.
