Abstract:5 months old Baerhu sheep（BS），Short fat-tailed sheep（SS）and Dorper×Hu sheep（DS）（n=10）with similar body weight（30.58±3.34）kg in captivity were compared by testing slaughter performance，eating quality and nutrition of longissimus dorsi（L），triceps brachii（T）and biceps femoris（B）to study the difference of the three breeds of sheep.The results showed that carcass yield，meat percentage，redness value（a*）and ash content of L，intramuscular fat（IMF）in L and T of DS were significantly higher than those of BS（p<0.05）；tenderness and ash content of L，cooking loss of T of BS were significantly higher than those of SS （p<0.05）；glycogen content of L of DS was significantly higher than those of the other two breeds，while carcass depth of it was significantly lower than that of other two breeds（p<0.05）.Respectively，brightness value（L*）of the three muscle tissue sites，yellowness value（b*）and the proportion of unsaturated fatty acids of L and B of SS were significantly lower than those of other two breeds（p<0.05），especially in α-linolenic acid（ALA），arochidonic acid（ARA），eicosapentaenoic acid（EPA），docosapentaenoic acid（DPA）and docosahexaenoic acid（DHA）.In conclusion，the three breeds of sheep had their own advantages and disadvantage on slaughter performance，eating quality and nutrition，namely，DS had better meat production performance and muscle color，higher intramuscular fat（IMF）and glycogen content，while SS has lower cooking loss，but higher proportion of unsaturated fatty acid and BS had better tenderness，but lower mineral content.
