Lamb meat survey was performed in the Basque Country and Navarre in order to characterize its fatty acid (FA) composition emphasizing on trans and CLA profiles. Samples were collected in spring (n=24) and winter (n=24) of 2013. Subcutaneous (SC) fat was analyzed by GC-FID. In general, very few differences were observed between collection periods. High variability was observed for trans-18:1 content and 2 different groups were clearly identified: 1) when trans-18:1 content was < 8%, 11t-18:1 was the predominant isomer; 2) but when trans-18:1 content was > 8%, 10t-18:1 was clearly the main isomer. The 2 groups were also clearly separated in the principal component analysis. The high variability observed among samples could be associated to different breeds and feeding managements.
