Within our studies of the profile of fatty acids of emerging row of the Portuguese autochthonous Alentejo local pig breed, we decided to emphasize the importance of odd chain fatty acids in the qualification and distinction of their final products. Therefore, we used samples of dorsal subcutaneous fat of 36 carcasses of Alentejo local pig breed (18♂♂castrated and 18♀♀females) spread over two (2) lots with different food management in the fattening stage (Lote1, n = 24, regime feed montanheira and the final third with herb spontaneous pasture and corn grain and Lote2, n = 12, feeding of montanheira and the final third with herb spontaneous pasture and triticale grain). From the analysis of the results, on average, in sums of odd chain fatty acids (Lote1 = 0.66 ± 0.13 and Lote2 =1.02 ± 0.33), we’ve found that the Lote2 showed a highly significant difference (P≤0.001) in relation to Lote1, which enabled us to distinguish the final products derived from the carcasses of pigs consumed grass and triticale in the final third of montanheira in maize. Thus, we conclude that by using the % of the sum of the profile of the odd-chain fatty acids it is possible to disentangle (fresh and / or processed end products) from the Alentejo local pig breed, according to the diet of grazing in the montanheira and, simultaneously, the substitution of corn in grain by triticale grains in animal husbandry will facilitate the mitigation of scarcity and food shortages caused by the degradation of the Mediterranean ecosystem.
