The present study was conducted to evaluate the efficacy of dietary supplementation of 0.5 and 1% of fatty acid (FA) compound containing conjugated linoleic acid as active component on growth performance, apparent nutrient digestibility, serum lipid profile, meat quality, and fatty acid profiles in muscle and adipose tissue in finishing pigs. A total of 90 finishing pigs ([Yorkshire × Landrace] × Duroc) were used in 5-week trial. The growth performance and nutrient digestibility were unaffected with FA supplementation. The lean percentage was greater (P = 0.05) in pigs fed FA-supplemented diet whereas the 2-thiobarbituric acid reactive substances value was reduced (P < 0.05) during the storage. The FA supplementation tended (P = 0.06) to reduce serum total cholesterol. However, it improved (P < 0.05) C14:0, C16:0, C18:0, saturated fatty acid, conjugated linoleic acid, and omega 3 levels and reduced (P < 0.05) C18:1, C18:2, unsaturated fatty acid, and omega 6 levels in muscle and subcutaneous adipose tissue. In conclusion, FA supplementation tended to reduce total serum cholesterol and improved lean percentage as well as meat value through enrichment of conjugated linoleic acid and omega 3 fatty acid in the muscle and adipose tissue.
