Fatty acid profile of slow-growing broilers supplemented with biocomplexed minerals
ABSTRACT: This study was conducted to evaluate the effects of dietary supplementation with biocomplexed selenium and chromium on the fatty acid profile of the breast and thigh of males and females broilers of the Label Rouge lineage. The experimental design was completely randomized arranged in a 3 x 2 factorial scheme corresponding to three diets (control; 0.40 ppm of chromium; 0.50 ppm of selenium) and two sexes. Each treatment consisted of three plots of five broilers. The fatty acid profile was evaluated in the breast and thigh samples. The addition of biocomplexed selenium in the broilers diets increased the content of long chain fatty acid of the omega 3 and 6 series (docosahexaenoic - DHA and arachidonic acids, respectively), the total of omega 6 and the stearic acid content on the breast (pectoralis major muscle). In addition, selenium supplementation caused a reduction in oleic acid content and in total of monounsaturated in the same muscle. Males had higher contents of linoleic and linolenic acids, and total of polyunsaturated; and lower content of oleic acid, total of monounsaturated and saturated in the thigh. The broilers supplemented with biocomplexed selenium and males presented better lipid quality in the muscle by breast and thigh, respectively.
