Abstract: This experiment was aimed to analyze the amino acids composition and nutrient value of Black Angus raised in Ujinmqin grassland and provide basic data for feeding,cross breeding,and meat quality evaluation.Highrib,tenderloin,ribeye,nates meat,topside,shoulder clod and brisket samples were collected from seven Australian imported Black Angus raised in Ujinmqin grassland with 500 kg?38 kg body weight.The content and composition of amino acids were determined and then nutritent value were analyzed using FAO/WHO amino acids pattern.The results showed that the moisture and crude fat of samples were 68.73% and 30.56%.There were total 17 kinds of amino acids were determined in the samples and UAA,SAA and BAA were abundant.The ratios of these three abundant amino acids to total amino acid (TAA) were 25.8%,32.7% and 41.6%,respectively.The EAA content,EAA/TAA,EAA/NEAA and the EAA scores were all higher than FAO/WHO amino acids pattern.The amino acids content of ribeye,tenderloin and highrib were higher than that of other parts of muscle.In conclusion,the meat of Black Angus raised in Ujinmqin grassland had abundant composition and high content of amino acids,which were able to provide enough nutrient elements for human beings.

Key words: Ujinmqin grassland; Black Angus; amino acids composition of muscle; nutrient value
