The contents of calcium， iron，manganese and zinc were higher than those of other varieties of mutton. Conclusion： The cholesterol content of Ordos fine wool muton is low; the content of calcium， iron， manganese and zinc is high.Amino acid composition is balanced， proline content is high. Only three amino acids and one mineral element were significantly different in biceps femoris，longissimus dorsi and triceps brachii （P<0.05 ）
