What is Effect of Dietary Conjugated Linoleic Acids on the Distribution of Fatty Acids in Serum Lipoprotein Fractions and Different Tissues of Growing Pigs about?

## Summary The effect of conjugated linoleic acid (CLA) on blood lipids [total cholesterol, high‐density lipoprotein (HDL), low‐density lipoprotein (LDL) and triacylglycerols (TAG)] and the fatty acid distribution of the lipoprotein fractions, backfat, muscle fat, and liver lipids were examined in an experiment with two groups of 40 pigs [Pietrain × (Landrace × Large White)] each. The 20 female and 20 male castrated pigs of each group were fed with isoenergetic and isonitrogenous diets supplemented with either 20 g/kg rapeseed oil (control) or 20 g/kg CLA–TAG. The CLA preparation contained 54.2% pure CLA consisting of approximately two‐thirds __cis,trans/trans,cis__‐isomers and one‐third __trans,trans__‐isomers. The fatty acids of lipoproteins, backfat, muscle lipids and liver lipids were analysed by gas chromatograph (GC). CLA supplementation did not significantly influence blood lipids and the LDL to HDL ratio. In the CLA‐fed pigs the very low‐density lipoprotein (VLDL) contained higher saturated fatty acid (SFA) concentrations at the cost of the monounsaturated fatty acids (MUFA). The percentage of polyunsaturated fatty acids (PUFA) remained unchanged. The highest CLA content wa
