Abstract

As today, eggs make an important remark to the human diet. Egg can also be a good source to be fortified with omega-3 polyunsaturated fatty acid (EPA and DHA) which differ based on the hen’s breed and their feeding. Several studies revealed that omega-3 PUFAs can lower blood pressure and serve as anti-inflammation which aid in cardioprotection. It is proven that Malaysian have deficient omega-3 fatty acid consumption, and this nutrient is mainly obtained from fish-based supplement. However, the major concern about this is the exposure of methylmercury found in fishes. Hence, this study was conducted to determine and compare omega-3 content in egg of chicken fed with common feed and extruded flaxseed. The eggs were provided by the company and were randomly collected according to their days. Next, the egg yolks were separated from albumen by using egg yolk separator before they were homogenized for total lipid and omega 3 content analysis. Omega 3 analysis consist of cold lipid extraction, methylation of fatty acid and gas chromatography. Samples were prepared in duplicate form and analyzed by using One-way ANOVA to determine mean and standard deviation. The result showed that there was no significant difference in total lipid content with (p > 0.05) between control and treatment group. Whereas for EPA content, Treatment Day 14th (1.06%) was significantly different with (p < 0.05) when compared with other group and selected days. As for DHA content, there was no significant difference when compared between the group and selected days. Nonetheless, the treatment group still have a higher amount of DHA compared to the control group. Overall, feeding hens with flaxseed can increase omega-3 content in egg and Day 14th is the optimum feeding days to enrich omega-3.
