Resumo |
We evaluated the influence of dietry inclusion of corn gluten meal, apocartenoic acid ethyl ester (APO-EE), canthaxanthin, and Rhodocylus gelatinosus R-1 biomass on broiler carcass color. These oxycarotenoid sources were used as pigment supplements to a basal ration containing yellow corn as the sole source of xnathophylls. Objective color values of L (lightness),C (chroma), and h (hue) were measured on skin and meat surfaces of broiler carcasses. on both surfaces, R. gelatinosus R-1 biomass oxycarotenoids enhanced the chroma values (color saturation), as compared to yellow corn xanthophylls, and tended to provide yellowness to broiler carcasses, whereas the APO-EE and canthaxanthin tended to provide redness. At the concentrations studied, R. gelatinosus R-1 biomass oxycarotenoids were less effective than APO-EE and canthaxanthin in enhancing color saturation. Lightness, chroma, and blue values did not differ significantly between males and females. However, skin showed significantly higher color saturation than meat in breast and thigh portions of the carcass. |
