We studied the feeding level-related variations in lipid characteristics in the adipose
tissues of pigs. The lipid content, fatty acid profile, oxidative stability, iodine value,
thrombogenic and atherogenic indices were determined in individual samples from 24
immunocastrated males (Duroc x Large White), fed either restricted or ad libitum. In
backfat, feed restriction increased the polyunsaturated fatty acid proportion and iodine
value and lowered the thrombogenic and atherogenic indices. Intramuscular lipid content
was reduced by restriction, which did not affect either the fatty acid composition or the
oxidative stability in both raw and cooked muscle. Feed restriction improved the
nutritional quality of lipids without impairing their technological attributes
