Abstract: A total of 270 54-wk-old Hy-Line Brown laying hens were allocated into 3 treatments with 6 replicates of 15 hens each. Hens in the control group were fed a basal diet, and hens in the test Ⅰ and Ⅱ were given the basal diet supplemented with 5.0 mg/kg apoester combined with either 2.5 or 5.0 mg/kg canthaxanthin, respectively. The results suggested that compared with the control group, hens in test Ⅰ exerted a decrease in malondialdehyde accumulation in the liver(P<0.05). Treatments increased values of Roche colorimetric fan, redness, and yellowness, and contents of canthaxanthin and lutein, but reduced lightness value in the egg yolk(P<0.05). The supplementation of apoester combined with canthaxanthin could improve color and pigment accumulation in the egg yolk, and combination of 2.5 mg/kg canthaxanthin with 5.0 mg/kg apoester could enhance antioxidant capacity in the liver of laying hens.
