Dietary Enrichment of Eggs with DHA Using Different Sources of Fatty Acids
Dietary Enrichment of Eggs with DHA Using Different Sources of Fatty Acids
Ω-3 polyunsaturated fatty acids (PUFAs), first of all α-linolenic (ALA, C18:3), eicosapentaenoic(EPA, C20:5) and docosahexaenoic (DHA, C22:6) acids are necessary for the brain development, the eyefunction, the prophylaxis of cardiovascular diseases etc. One hundred and forty ISA Brown hens(n=20/treatment), 60 weeks old were fed with diets containing sunflower (2.5%), soybean (2.5%), fish oil (1.5and 2.5 %) or marine algae (1.5 and 2.5 %) in a period of 45 days. There was a significant (P
