Perfil de ácidos grasos de la carne de pollos alimentados con diferentes fuentes de aceites

The aim of this study was to evaluate the effect of different oils (soybean, sunflower, canola, and chicken) in chicken feed, created for broiler performance. The contents of fatty acid profile, cholesterol in chicken meat parts (breast and thigh) and their respective performance as broilers were analyzed. The 1,000 males Cobb broiler chickens to obtain 42-day-old, they have been solely fed with a specific diet, and after this period slaughtered. Chickens utilized as control were slaughtered at 21-day-old, this chickens classified as default were fed a commercial diet. The broiler performance, cholesterol content and physicochemical composition of feed diet in the chicken meat cuts (skinless breast, breast with skin and skinless thigh) are reported as not affected by specifying alimentation. Fatty acid profile of feed diet varied from each oil used in the formulation, where lower values of saturated fatty acid (SFA) verified in feed formulated with canola and sunflower oils. In chicken meat, the results for skinless thigh, skinless breast, and breast with skin, were similar to the fatty acid profiles, only varying the type of feed treatment. After samples analysis, the polyunsaturated fatty acid (PUFA), that appear in greater concentration, are 18:2n-6 and 18:3n-3. Accordingly, cuts from chickens fed with sunflower and soybean oils evidenced higher levels of 18:2n-6. Variously, cuts from chicken fed with canola oil demonstrated highest levels of 18:3n-3, when compared with others treatments. Considering the balance of n-6/n-3 and concentration of unsaturated fatty acid in chicken meat, chickens fed with canola oil expressed greater nutritional characteristics.
