Abstract： InordertostudythemeatqualitycharacteristicsofWannancatleand Simmentalcrossbredcatle，，42-monthold， healthy and disease-free male Wannan cattle and Simmental crossbred cattle （Simmental ？ per breed） wereslaughteredand longissimusdorsibicepsfemorisandmusculusobliquusexternusabdominisweretakenforanalyses of meatqualityatributesand determinationof proximate nutrients，mineral elementsandaminoacids，etc.Theresults showedthatcomparedto Simmentalcrossbredcatte，biceps femoris from Wannancattleexhibitedsignificantlyhigherash and copper contents （P<0.05 ）andmusculusobliquusexternusabdominishad significantlylower fatcontent （P<0.05 and highly significantly higher phosphorus content （P<0.01 ）.The amino acid content of each muscle from both breeds met the FoodandAgricultureOrganization/WorldHealthOrganizationcriteriaforhigh-qualityprotein，butthecontentofumami amino acids in each muscle from Wannan catte was higher than that ofthe Simmental crossbred catte.The contents of C14;0， C18：2n-6 and C20：4n-6 in longissimus dorsi and the C20;4n-6 content of biceps femoris from Wannan cattle were significantly higher than those of the Simmental crossbred catle （P<0.05 ，the C16：1 content of longissimus dorsi and the C14;0 and C16：1 contents of biceps femoris were highly significantly higher （P<0.01） ）， and the contents of C16：1 C17：1 and C20：4n-6 in musculus obliquus externus abdominiswere significantly lower（ （P<0.05） .Interms of muscle fiber characteristics，themuscle fiber diameter of all three muscles from Wannan catte was highly significantly lower than that of the Simmental crossbred catle （P<0.01） ）， whilethemusclefierdensityofbiceps femorisandmusculus obliquus externus abdominis was highlysignificantly higher （P<0.01） ）andthatof longissimusdorsiwassignificantlyhigher （P<0.05） .Insummary，Wannanbeef hadhigher totalamino acidcontent，umami aminoacidcontent，totaleetialaminoacidcontentandbetermusclefibercharacteristics，showing the potential to be high-quality beef.
