Polyunsaturated fatty acids (PUFAs) have beneficial effects on human and animal health. Moreover, the imbalance of the omega-3/omega-6 ratio leads to many physiological disorders. Poultry products are the main source of fatty acids. The dietary enrichment with oils containing PUFAs is one of the most effective solutions to increase the level of essential fatty acids in poultry products and consequently improve the health of poultry and humans as consumers [1]. The last studies reported that PUFAs supplementation reduced total cholesterol and triglycerides in poultry products [2]. Recently the vegetable oils such as flaxseed and echium oils have been considered as supplementation in the poultry diet [3,4]. This study evaluated the effect of enrichment of finisher diet with Echium amoenum and Linum usitatissimum (flaxseed) seeds oil and their combination on the serum level of cholesterol and triglyceride in Japanese quail. The study included 4 groups (n=10) as follows; 1.Basal diet, 2.Basal diet + flaxseed oil (4%), 3.Basal diet + echium oil (4%), 4.Basal diet + (flaxseed oil (2%) + echium oil (2%). The serum level of triglyceride in group 4 significantly decreased compared to groups 2 and 3 (P<0.05). Furthermore, the reduction of serum level of cholesterol was observed in all treatment groups which was significant in group 3 (P<0.05). Overall, it seems the supplementation of quail´s finisher diet with the combination of echium and flaxseed oils improves the level of serum lipid.
