Studies using flaxseed and chia seed as a dietary source have reported the detection of the do-3 fatty acids, EPA, and DHA in eggs(Ferrier and others 1995; Van Elswyk 1997b; Ayerza and Coates 1999, 2000, 2001; Bean and Leeson 2003; Antruejo and others 2011).
However in our study, ay-3 fatty acids were only detected in eggs from hens fed with the diet supplemented with
fish oil(Figure 3).
This could be due to the type of w-3 in the plant sources used in the study and its concentration at the levels of application.
//// Ideally, w 3-enriched products should reflect the nutritional profile of fish oil and contain EPA and DHA. However, EPA and DHA were not detected in eggs from hens given diets supple- mented with flaxseed and chia.
This may be due to the several limitations faced during the course of the trial such as the selective eating of feed resulting in insufficient consumption ofthe the short time period of the feeding trial.
Factors such as the short
