ABSTRACT The aim of the research was to determine lipid metabolism indices and fatty acid profile in the blood serum of Ross 308 chickens (n = 48), fed a finisher mixture supplemented with 0, 0.25, 0.5 and 1.0% of lignocellulose. The feeding trial lasted from 21 to 42 d of the birds' age. Blood samples were collected from each chicken at 42d of age from the pterygoid canal vein. In the blood serum the content of triglycerides (TG), total cholesterol (TCHOL) and high density lipoprotein (HDL) fraction was determined by the spectrophotometric method. The fatty acids concentration was estimated with the use of the gas chromatography method. Lignocellulose in doses of 0.5 and 1.0% significantly reduced the concentration of triglycerides and low density lipoprotein (LDL) fraction. Saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) content was not affected by dietary treatments whereas lignocellulose significantly influenced the profile of polyunsaturated fatty acids (PUFA) from n-3 and n-6 families. Insoluble fiber decreased (p< 0.05) serum concentration of a-linolenic acid (C18:3n-3) and increased share of docosahexaenoic acid (C22:6n-3), dihomogammalinolenic acid (C20:3n-6) and arachidonic acid (C20:4n-6) in total PUFA, compared to the control birds. The results of the present study have shown that the incorporation of limited amounts of lignocellulose into the broiler diet can influence the lipid metabolism in the chickens.
