| Yeast cell wall (YCW) products are a well-established class of prebiotics widely used in aquafeeds. Numerous studies have investigated the effects of YCW on growth performance, feed utilization, and immune responses in sturgeon species. However, limited information is available regarding their effects on oxidative status. Therefore, the present study evaluated the effects of ImmunoWall®, a commercial YCW-based prebiotic, on hepatic oxidative status in juvenile Persian sturgeon (Acipenser persicus). Fish were fed diets supplemented with 0% (control), 0.5% (group I), and 1% (group II) ImmunoWall® for eight weeks. At the end of the feeding period, liver samples were collected and analyzed for malondialdehyde (MDA) content as well as superoxide dismutase (SOD) and catalase (CAT) activities. The results showed that MDA levels and the activities of SOD and CAT were significantly higher in both supplemented groups than in the control group (p < 0.05). These findings indicate that dietary ImmunoWall® supplementation altered hepatic oxidative status and stimulated antioxidant defense responses in juvenile Persian sturgeon. Further studies involving liver biochemical and histopathological assessments are required to clarify the physiological significance of these changes and to determine the long-term effects of YCW supplementation on liver health. |
