PIGMENTAÇÃO DA PELE E RENDIMENTO DE CARCAÇA DE FRANGOS LABEL ROUGE ALIMENTANDOS COM DIETAS CONTENDO DIFERENTES PIGMENTANTES

It was aimed at to evaluate the effects of the wheat inclusion + pigmentants in the diet of broilers of the lineage Label Rouge, reared with access to the free area, on carcass yield, noble cuts and skin pigmentation. A total of 480 chickens of slow growth, males, they were distributed in a delineate entirely randomized with four treatments and four repetitions, the experimental diets were: basal ration (corn, bran soybean and 2% of wheat); basal ration + 0,002% of lutein; basal ration + 0,002% of canthaxanthin; basal ration + 0,001% of canthaxanthin + 0,001% of lutein. The inclusion of 2% wheat + pigmentants in the ration didn't provoke significant effects for the carcass yield, noble cuts and chest color, already the color of the thigh + drumstick was influenced by the addition of pigment in the diet. The inclusion of 2% wheat + 0.001% canthaxanthin + 0.001% lutein in the slow growing chickens diet does not affect carcass yield and noble cuts and improves skin pigmentation of the thigh + drumstick.
