Traditional linseed varieties are characterized by a high content of fat, including
linolenic acid (LNA; C18:3 n-3); when used in feeding animals, especially poultry,
they make it possible to obtain products with functional food properties. The use of
linseed or linseed oil in diets of laying hens representing high-producing commercial
lines enriches the eggs with unsaturated fatty acids (n-3 PUFA), mainly LNA, as well
as eicosapentaenoic (EPA; C22:5) and docosahexaenoic acids (DHA; C22:6) formed
from LNA (Botsoglou et al., 1998; Bean and Leeson, 2003; Sosin et al., 2006). In
studies aimed at enriching eggs, it is necessary to determine if the introduction of
acid sources will reduce productivity or adversely affect physical characteristics of
eggs. A study with ISA Brown hens (Połtowicz and Wężyk, 2005) revealed that linseed
supplemented to layer diets has a favourable effect on yolk colour while slightly
reducing its cholesterol content. All physical characteristics of eggs were improved
