Effects of high linolenic acid diet supplemented with synthetic or natural antioxidant mix on live performance, carcass traits, meat quality and fatty acid composition of Longissimus thoracis et lumborum muscle of medium-heavy pigs

We studied the effect of a high linolenic acid diet supplementation with synthetic (vitamin E + selenium) or veg-etal mix rich in natural antioxidants (grape skin oregano) on live performances, carcass and meat quality, fatty composition oxidative stability intramuscular lipids Longissimus thoracis et lumborum muscle medium-heavy pigs. Neither traits nor chemical proximate was affected by dietary treatments. Linseed inclusion reduced n-6:n-3 polyunsaturated acids ratio increased long-chain n-3 precursor, fundamental for human health. Our results offer new opportunities to use products more acceptable consumers are eco-friendly.
