초록

The purpose of this study was to examine oxidative stress induced by dietary vanadium in the mucosa of different parts of intestine including duodenum, jejunum, ileum, and cecal tonsil. A total of 420 1-day-old avian broilers were divided into six groups and fed on a corn-soybean basal diet as control diet or the same basal diet supplemented with 5, 15, 30, 45, and 60 mg/kg vanadium as ammonium metavanadate. During the experimental period of 42 days, oxidative stress parameters were determined for both control and experimental groups. The results showed that malondialdehyde content was significantly higher (p < 0.05 or p < 0.01) in 30, 45, and 60 mg/kg groups than in control group. In contrast, the activities of superoxide dismutase, catalase, and glutathione peroxidase, and ability to inhibit hydroxyl radical, and glutathione hormone content were significantly decreased (p < 0.05 or p < 0.01) mainly in 45 and 60 mg/kg groups in comparison with those of control group. However, the abovementioned oxidative stress parameters were not significantly changed (p > 0.05) in 5 and 15 mg/kg groups. It was concluded that dietary vanadium in excess of 30 mg/kg could cause obvious oxidative stress in the intestinal mucosa, which could impact the antioxidant function of intestinal tract in broilers.
