Study was conducted to ascertain the influence of lipid blends on the fatty acid composition of some chicken tissues. The relationship between dietary and tissue fatty acid composition as well as desimilarities between tissues were also studied. Three diets composed from identical basal ingredients were fed to 3-week-old female Ross I broiler chicks. The diets were supplemented with lipid blends derived from tallow (TL) and oils of soyabean (SBO), marine (MO) or corn (CO). The study lasted for 35 days in the spring/summer of 1990. In breast muscle lipid (BML), significant (P0.05) differences were observed between the treatments in linoleic, linolenic and C22 polyunsaturated acids (PUFAs). Significant (P0.05) differences were also found in the concentrations of oleic, linoleic and C20-C22 less saturated fatty acids in subcutaneous fat (SCF). There were highly significant (P0.01) positive correlations between the dietary and tissue fatty acid compositions. SCF was found to be richer than BML in most fatty acids. The fatty acid contents of broiler chicken meat could be manipulated to suit market demand through the feeding of the appropriate lipid sources of blends.
