dc.description.abstractThe fatty acid profile and the related indices of the nutritional quality of breast and thigh muscles were studied in two lines of chickens - La Belle (LB) and White Plymouth Rock (WPR) - slaughtered at the age of 9 and 18 weeks. The fatty acid profile was more affected by the age than the line of the birds; however, the influence of both differed between the breast and thigh. The content of total saturated fatty acids (SFAs) increased in the thigh (P (lt) 0.01), while that of the monounsaturated fatty acids (MUFAs) decreased with age in both muscles (P (lt) 0.001). This corresponded to the significant decrease in C18:1 in the older chickens and the lower desaturase activity (P (lt) 0.001). The contents of C20:4n-6, C22:5n-3 and C22:6n-3 and the total amount of polyunsaturated fatty acids (PUFAs) in breast were higher (P (lt) 0.001) at the age of 18 weeks. A similar pattern in the individual and total PUFA was observed in the thighs. The effect of line was more visible in the breast, leading to a lower C14:0 content and C20:5n-3 and a higher C18:0 content in the WPR chickens (P (lt) 0.001), corresponding to the higher elongase and thioesterase indices in these birds. Both atherogenic (AI) and thrombogenic (TI) indices were lowered, while the ratio of hypocholesterolemic / hypercholesterolemic fatty acids (h / H) and polyunsaturated / saturated fatty acids (P / S) increased in the breast of the birds at 18 weeks. In breast and thigh meat, the ratio of n-6 = n-3 PUFA decreased in the older chickens (P (lt) 0.001).en
