tissue, but with no increase in DPA. Similar results were
obtained in studies in lambs and beef cattle in which a twofold increase of EPA and DHA levels were recorded in m.
longissimusu dorsi after the addition of fish meal in feed.
Since it is rather difficult to change the human nutritional habits, and there are also disputes regarding the
consumption of fish species rich in n-3 unsaturated fatty
acids, that are also on the top position of the food chain
with a higher accumulation of harmful substances present
in sea water, it would be useful to change the strategy of
nutrition in the farm animals. That would enable to obtain
the nutritional value of fatty acid composition in foods as
close to the recommended criteria as possible. It could be
concluded that by increasing the content of n-3 unsaturated fatty acids in feed inevitably influences both the
accessibility and intake of foods of appropriate fatty acid
composition, and thus contributes to the prevention of the
increasing occurrence of chronic diseases.
