Effect of dietary natural astaxanthin (ASTA) supplementation on antioxidant enzyme activity and free radicals in the seminal plasma of aging layer breeder roosters. (a-c) Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activity in the seminal plasma. (d-e) Scavenging free radical abilities in the seminal plasma. (f) Malondialdehyde (MDA) level in the seminal plasma. (g) Total antioxidant capacity (T-AOC) in the seminal plasma. The data represent mean ± standard deviation; n = 6 in each group. a–d Means within a row with no common superscripts differ significantly (P < 0.05)
