An experiment was carried out to compare the proportions of fatty acids in conventional and enriched ω-3 commercial yolk eggs. In group 1, 432 birds were fed throughout productive life with basal diet of corn and soybean meal (production of conventional eggs) and in group 2, the others hens, from the 22nd week-old, was added to the basic diet, 1.5% of substrate of marine algae and 1.8% of fish oil (production of designer ω-3 eggs). There were randomly collected 180 eggs from each group of hens and those distributed in complete randomized blocks design, considering one egg as a replicate. The proportions between unsaturated/saturated fatty acids, polyunsaturated ω-6/ ω-3 series, linoleic/alpha-linolenic acid, arachidonic/docosahexaenoic eggs enriched with ω-3 were lower than conventional eggs. The interrelationships between fatty acid studied of the ω-3 enriched eggs were lower than conventional eggs, and, accordingly, within the ideal threshold value for fat consumption by humans.
