Concentrate fed lambs, as Spanish lambs, displayed the highest proportions of linoleic acid (C18:2), while Uruguayan lambs, reared under extensive grazing conditions, showed the highest proportions of linolenic acid (C18:3), due to the great concentration of this fatty acid in grass. German and British lambs, which were fed grass and concentrate, displayed intermediate proportions of linolenic acid (C18:3). Heavy Uruguayan lambs had higher intramuscular fat content (5.92%) than German (4.25%) and British (4.32%) lambs, and this content was twofold higher than light lambs (Spanish (2.41%) and light Uruguayan (3.05%)). Heavy Uruguayan, German and British lambs had a low polyunsaturated/saturated (P/S) ratio due to their high saturated fatty acid (SFA) content and proportion. Principal component analysis was performed to study the relationship between fatty acids. Spanish lambs were clearly separated from the other types and were situated close to the proportions of short chain and n 6 fatty acids and n 6/n 3 ratio in the data plot for fatty acid proportions. Light Uruguayan lambs were located close to long chain fatty acids, and heavy Uruguayan and British lambs were placed near the antithrombotic potential (ATT), stearic acid (C18:0), SFA and conjugated linoleic acid (CLA) proportions. German lambs were located between Spanish lambs and the other types. aACIDOS GRASOS aALEMANIA aCARNE aCORDERO aESPAÑA aREINO UNIDO aURUGUAY aFATTY ACIDS aLAMB aMEAT ORIGIN aPRODUCTION SYSTEM1 aALVAREZ, I.1 aDE LA FUENTE, J.1 aSAÑUDO, C.1 aCAMPO, M.M.1 aOLIVER, M.A.1 aFONT I FURNOLS, M.1 aMONTOSSI, F.1 aSAN JULIÁN, R.1 aNUTE, G.R.1 aCAÑEQUE, V. tMeat Science, Volume 71, Issue 2, October 2005, Pages 256-263.
