Abstract：In order to explore the nutritional quality of the meat of Gobi short-tailed sheep in Baotou, Inner Mongolia, 12 six-month-old lambs were selected in this experiment. After slaughter, Biceps femoris, Triceps brachii and Longissimus dorsi muscles were taken to determine physicochemical properties, fatty acids, amino acids, mineral elements, and other nutrients. The results showed that the pH24 h of the muscles was about 5.66, the moisture content was 70.47%, the crude fat content was 7.37%, the crude protein content was 21.43%, and the mineral content was 3.00%. The dominant fatty acids in the skeletal muscles were C6:0, C10:0, C16:1 and C22:0. Among the determined amino acids, glutamic acid was the most abundent, followed by aspartic acid, leucine, lysine, arginine and so on. The content of threonine as an essential amino acid for humans in Longissimus dorsi was significantly higher than that in Biceps femoris (P < 0.05), and that in Triceps brachii was in the middle. No significant difference was found among the three msucles in other essential amino acids. The contents of calcium, sodium, magnesium, copper, zinc, iron, and manganese but not potassium were significantly different among the three skeletal muscles ( P < 0.05).
