A total of 225 ISA Brown layers, 63-wk-old, were used in a 5-wk feeding trial to measure the effect of dietary canthaxanthin(0, 50, 100, 200, and 300mg/kg feed) on its accumulation in various body parts and the egg yolk. There were three replications per treatment and 15 birds per replication. The redness(a$^$*/) and yellowness(b$^$*/) of wing and thigh skin significantly(P＜0.05) increased when canthaxanthin was fed at 2200 and 250mg/kg feed, respectively. However, the color of breast skin was not significantly affected by the canthaxanthin supplementation. Skin lightness(L$^$*/) was not influenced by the dietary canthaxanthin. The dietary canthaxanthin supplementation did not significantly affect the redness or the yellowness of breast and thigh muscles. However, feeding canthaxanthin at 300mg/kg, compared to the control(0mg/kg feed), significantly(P＜0.05) decreased the lightness of wing and breast muscles. Feeding of canthaxanthin for 1-3d also significantly increased the color of egg yolks. In conclusion, canthaxanthin can be used to improve the color of skin and egg yolks, but it should be used cautiously because too intense egg yolk redness could be rejected by consumers.
