Genetic group was a significant source of variation for intramuscular fat content, individual fatty acids, polyunsaturated fatty acid (PUFA)/saturated fatty acid (SFA) ratio, total PUFA, essential fatty acids (EFA), total n-3 and n-6 PUFA and ?9 desaturase and atherogenic index. MO breed presented the highest values of conjugated linoleic acid, PUFA (similar to F1) and PUFA/SFA (similar to F1). MO meat had the highest proportion of EFA, despite the value was similar to F1. SO breed showed highest proportion of myristc, pentadecanoic, palmitic and palmitoleic acids in muscle, and highest ?9 desaturase indices. In conclusion, there are differences between genetic group for the profile of fatty acids and intramuscular fat. The meat from MO lambs had better attributes of fatty acid composition with higher PUFA, PUFA/SFA ratio, EFA and total n-3 PUFA. aconjugated linoleic acid aFatty acids aFinishing aLamb meat aLinoleic acid aLipids aMeat quality aMutton aSheep aÁcido graxo aCarne aCordeiro aLipídio aOvino aQualidade aTerminação aÁcido linoléico conjugado aCLA aPastagem irrigada1 aBOMFIM, M.
