Effect of dietary natural astaxanthin (ASTA) supplementation on the antioxidant enzyme activity and free radicals in kidneys of aging layer breeder roosters. (a-c) Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activity in the kidney. (d-e) Scavenging free radicals’ abilities in the kidneys. (f) Malondialdehyde (MDA) level in the kidneys. (g) Total antioxidant capacity (T-AOC) in the kidneys. The data represent mean ± standard deviation; n = 6 in each group. a–c Means within a row with no common superscripts differ significantly (P < 0.05)
