Effects of varying concentrations of bottle gourd (Lagenaria siceraria) seed oil (0, 100, 200, and 400 µL/mL of extender), denoted as BG0, BG100, BG200, and BG400, respectively, on the antioxidant status of chilled rabbit semen stored at 4 °C for 72 h. The parameters evaluated were GPx (Fig. 5A), SOD (Fig. 5B) and TAC (Fig. 5C). Within each parameter, bars with different superscript letters (a, b, c) indicate statistically significant differences between treatment groups (P < 0.05)
