Abstract:

To study the effect of monochromatic light on antioxidative capacity of skeletal muscle in broiler during late-embryonic stage, a total of 225 AA broiler fertilized eggs were randomly divided into 5 groups and were incubated under white light, blue light, green light, red light and dark conditions, respectively. The pectoralis major and gastrocnemius muscles were taken at the 15th, 18th and 21st day of embryonic age (abbreviated as E15, E18 and E21, respectively). The activity of antioxidant enzymes (SOD, GSH-Px and CAT), total antioxidant capacity (T-AOC) and the content of malondialdehyde (MDA) were measured. Results were as follows:① At E18 and E21, the antioxidant enzymes activity and T-AOC levels in the white light group were higher than those in the dark group (0.92%-32.79%), but the MDA content was decreased (1.75%-10.32%); ② Compared with the white light group, especially at E18 and E21, the anti-oxidative enzyme activity and T-AOC levels in the green light group were significantly increased (1.72%-51.29%, P<0.01) and the MDA content was significantly decreased (8.78%-18.26%, P<0.05). The anti-oxidative enzyme activity and T-AOC levels under the blue light were increased (0.84%-39.48%) and the MDA content was decreased (2.35%-11.20%). However, the degrees of increase and decrease under the blue light were lower than that of the green light group. In contrast, the red light reduced the anti-oxidative enzyme activity and T-AOC levels (2.29%-28.17%) and increased the MDA content (0.51%-18.08%). Our results suggeste that the monochromatic green light illumination can enhance the antioxidation function of skeletal muscle in the late-embryonic stage of broiler, but monochromatic red light has inhibitory effect.
