[Abstract]:[objective] to study the meat quality characteristics and influencing factors of Kirgiz sheep, so as to protect the germplasm resources of Kirgiz sheep. To provide a scientific theoretical basis for the rational development of Kirgiz sheep and tissue production. [methods] taking Xinjiang Kirgiz Sheep as the research object, we studied the same conditions of captivity. The contents of routine nutrients, physicochemical indexes, mineral elements and amino acids in skeletal muscle of Kirgiz sheep at 7 and 20 months of age. [results] crude fat in skeletal muscle of Xinjiang Kirgiz sheep was affected by different ages. Crude ash, crude protein, tenderness of mutton, iron, zinc, calcium, magnesium, copper, amino acid composition and total amino acid contents had significant effects on P0.01. [conclusion] Kirgiz sheep's skeletal muscle protein, fat, inorganic matter, zinc, calcium, magnesium, copper and other mineral elements, amino acid species and the number of the richer, but the tenderness decreased, after slaughter for 2 hours, the pH value of mutton maintained at 5.58 ~ 5.83.
