FATTY ACID COMPOSITION OF POULTRY MEAT FROM FREE RANGE REARING

Two provenances of broiler chickens (Ross and Prelux-bro) were (50 males and 50 females) were subjected to an extensive indoor rearing followed by a free-range rearing for a half of the population during the first 28 days. The age of chickens when slaughtered was 56 days. The fatty acid composition of breasts with skin (white meat) and legs with skin (dark meat) was analysed. Analyses of the fatty acid composition were performed with an in situ transesterification and a capilary column Gas -Liguid chromatography. Chickens reared outdoors have a more favourable fatty acid composition than those of the extensive indoor rearing: the share of essential fatty acids (the linoleic a., the a-linolenic a.) as well as polyunsaturated omega-3 and omega-6 fatty acids is greater. The Prelux-bro provenance has a favourable ratio of fatty acids in both types of rearing. Breasts have a better fatty acid composition than legs.
