Oxidized Oils and Oxidized Proteins Induce Apoptosis in Granulosa Cells by Increasing Oxidative Stress in Ovaries of Laying Hens

Figure 6

Effect of dietary oxidized oil and oxidized protein on ovary antioxidant enzyme activity of laying hens. Antioxidant enzyme activity assay was performed in the ovary in which small yellow follicles and hierarchical follicle were excluded. Values are the (). Means without a common letter are different; . FP: fresh protein; OP: oxidized protein; FO: fresh oil; OO: oxidized oil; MDA: malondialdehyde; SOD: superoxide dismutase; GSH-Px: glutathione peroxidase; T-AOC: total antioxidant capacity.
