Figure 2

Ovarian antioxidant and oxidant levels in hens at different ages. (a) Ovarian antioxidant levels in hens at different ages. Levels of GSH A, T-AOC B, T-SOD C, CAT D, GSH-Px E, and GSH-ST F were determined in the ovary at the age of 90, 150, 280, and 580 days. (b) Ovarian antioxidant levels in hens at different ages. Levels of MDA A, H₂O₂ B, and ROS C were determined in the ovary at the age of 90, 150, 280, and 580 days. Data were expressed as the means ± s.e. (). Different capital and lowercase letters indicate a very significant difference () and significant difference (), respectively.
