Fatty Acid Compositions of Some Feed Raw Materials in Poultry Diets

Abstract

In this study, total fat content and fatty acid composition of 5 feed raw materials in animal source and 10 feed raw materials in vegetables source were determined by gas chromatography. Polyunsaturated fatty acids (PUFA) were found to be higher than saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) in all samples except for rendering oil, tallow and meat bone samples. Palmitic acid was the major saturated fatty acid (7.65-20.31 % of total fatty acids) in all samples except for rendering oil and tallow. Oleic acid was identified as the major mono-unsaturated fatty acid (14.39- 40.00 % of total fatty acids) in all samples. Linoleic acid was the most abundant polyunsaturated fatty acid (2.53-60.80 % of total fatty acids) in all samples except for fish oil and fish meal. It was shown that the fatty acid composition, ω3/ω6 fatty acids ratio and SFA/PUFA ratio between the raw feed materials in poultry diets were varied.
