ABSTRACT

As reported previously, meat from nutria fed diets rich in protein is characterised by an unfavourable fatty acid profile. In the present study we tried to improve health-promoting properties of nutria meat by modifying the fatty acid concentrations with dietary supplementation of 1% of linseed oil or 1% of apple seed oil. The intramuscular fat of nutrias fed the diet with apple seed oil was characterized by a higher level of polyunsaturated (PUFA) and essential fatty acids (EFA) but not monounsaturated fatty acids (MUFA). n-6:n-3 PUFA ratio in meat of nutrias fed apple seed oil was most favourable for consumers, despite the similar content of C18:3 n-3 in ether extract in feed mixtures for nutria.

Key words: nutria, linseed oil, apple seed oil, meat, fatty acids.
