This study was conducted to assess the effects of flaxseed oil and dried whitebait as a source of ${omega}$-3 fatty acids (${omega}$-3 FA), which could be used to produce eggs enriched with ${omega}$-3 FA, and of fructo-oligosaccharide (FOS) as a source of prebiotics on performance of hens (commercial Hy-Line Brown laying hens), and FA composition, internal quality, and sensory characteristics of the eggs. Dietary FOS increased egg weight. The amounts of ${alpha}$-linolenic (ALA), eicosapentaenoic (EPA) and docosahexaenoic acids (DHA) in the eggs from the hens fed the flaxseed oil alone or flaxseed oil+dried whitebait diets were higher than those of the control. Hedonic scores for off-flavor, fishy flavor, buttery taste and overall acceptability of the eggs from the hens fed the diet containing flaxseed oil+dried whitebait were lower (p<0.05) than those of the control. Overall acceptability of the eggs from the hens fed the diet containing soybean oil+dried whitebait was lower (p<0.05) than that of the control. However, all the sensory attributes of the eggs from the hens fed the diet containing flaxseed oil, dried whitebait and FOS were not significantly different from those of the control. These results confirmed that flaxseed oil increases the ALA content in the eggs and a combination of flaxseed oil and dried whitebait increases EPA and DHA in the eggs. Of significance was that addition of FOS to the flaxseed oil+dried whitebait diet improves the sensory characteristics of the eggs enriched with ${omega}$-3 FA.
