Abstract: The aim of this study was to determine the effects of varying combinations of dietary selenium (Se), vitamin E (Vit E), and zinc (Zn) supplements on antioxidant enzyme activity, and developmental and histological traits in testicular tissues of 1-year-old native Turkish ganders. A total of 48 animals were used and randomly assigned to 8 treatment groups (control, Se, Vit E, Zn, Se + Vit E, Se + Zn, Vit E + Zn, and Se + Vit E + Zn), with 6 birds in each group. In addition to the control (basic) diet, specific levels of supplements (0.3 mg/kg Se, 100 mg/kg Vit E, and 100 mg/kg Zn) were added to the diet of each treatment group. Antioxidative enzymes (superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase activities, and malondialdehyde level) were more advantageous in the testicular tissue of ganders fed with Se + Vit E + Zn. Malondialdehyde (MDA), which is an important indicator of lipid peroxidation, was not significantly affected by the dietary treatments. However, it was negatively correlated with the seminiferous tubule area (−0.34) and diameter (−0.35). Compared to the control, the highest seminiferous tubule area and germinative epithelial thickness were determined as being fed with Se + Vit E + Zn. The lowest seminiferous tubule diameter was determined in the control and Zn groups, while the highest was in the group fed with Se + Vit E + Zn and Se + Vit E. This study showed that the simultaneous supplementation of Se + Vit and E + Zn into the diet of native Turkish ganders had positive effects on the testicular tissue, by reducing oxidative damage and improving histological parameters without affecting their physiological status.
