Effect of diets with different fatty acid pattern on the content of fatty acids in chicken meat

Popis výsledku v původním jazyce

Effects of 1, 3, 5 or 7 % of linseed oil in the diet on the content of fatty acids in breast and thigh meat were studied in broiler chickens. Oils made either of seeds of the linseed cultivar Atalante (A) with a high content of alpha-linolenic acid or ofthe cultivar Lola (L) with a predominating content of linoleic acid were fed from 25 to 40 days of age. When feeding A, contents of all n-3 polyunsaturated fatty acids (PUFA), including eicosatrienoic acid, were significantly higher, those of n-6 PUFA were lower, and the ratio of n-6/n-3 PUFA was narrower (P<0.001) than when L was fed. The narrowest n-6 to n-3 PUFA ratio was observed at the content 36 g of alpha-linolenic acid (58 g A) per kg of the diet while the widest one at 2 g of alpha-linolenic acid (70 g L) per kg of the diet. When using L, the increasing level of linoleic acid in feed was associated with significantly increasing levels of all n-6 PUFA in meat. By means of oil A, the content of all n-3 PUFA increased, but the de
