Purpose:: Current study is a content analysis of papers in the field of egg enrichment with omega-3 fatty acids, to identify the trend, scientific prosperities and the main roles of this area during 2003-2013.
Methodology: All published papers related to egg enrichment with omega-3 fatty acids by modifying hen's diet were extracted from the journals of Poultry Science, British Poultry Science and Journal of Applied Poultry Research and exposed to content analysis.

The USA was the most productive country sharing 37.77% of papers.  Surprisingly, Iran did not have any paper in this field. Flaxseed and fish oil were common dietary ingredients which were used in research. Research in the field of egg enrichment with omega-3 fatty acids was increased egg α-Linolenic acid, Eicosapentaenoic acid, Docosapentaenoic acid, Docosahexaenoic acid and total n-3 contents by 10.98%, 1.4%, 0.6%, 7.45% and 12.13% of yolk fatty acids. Research in the field of egg enrichment with omega-3 fatty acids led to supply omega-3 fatty acids required amount for health people and cardiovascular patients.
