Abstract: Zhaowuda meat sheep is a new variety of meat sheep bred in Chifeng City through years of efforts.The slaughter performance and meat quality were compared between Zhaowuda sheep and Mongolia wether after slaughter.The results showed that the dressing percentages of Zhaowuda sheep and Mongolia wether were respectively 57.79% and 44.32%,and their carcass meat rates were respectively 71.08% and 65.75%.The slaughter rate and carcass meat rate were significantly higher in Zhaowuda meat sheep than in Mongolia wether（P0.01）.The analysis on meat quality showed that the shear strength had no significant difference between Zhaowuda sheep and Mongolia wether.The Zhaowuda meat sheep had intramuscular fat content of 3%-4% and protein content higher than 20%.The contents of necessary amino acids accounted for more than 50% of the ideal protein standard,and the contents of lysine and histidine were higher than the ideal protein standard.The content of flavor amino acids in muscle was significantly higher in Zhaowuda meat sheep than in Mongolia wether（P0.05）.They had similar composition of fatty acids,mainly oleic acid,stearic acid and palmitic acid.The contents of linoleic acid and linolenic acid were significantly higher in Zhaowuda meat sheep than in Mongolia wether（P 0.05）.Therefore,Zhaowuda meat sheep have good flavor and high nutritional value.
