on the lipid composition of the diet. Flachowsky et al. (2008) showed strong correlations between the intake and concentration of polyunsaturated fatty acids in backfat (r = 0.85). In addition, linoleic and α-linolenic acids are dietary precursors of the longer chain (C20-22) fatty acids of the n-6 and n-3 series. The fatty acid profile of meat can be easily modified through feeding, thereby improving the quality of pork for the consumer and meeting nutritionists’ recommendation (Mourot and Lebret, 2009).
