The aim of this study was to investigate the effects of high dietary fluoride (F) on serum biochemistry and oxidative damage in broiler chickens. 280 one-day-old healthy avian broiler chickens were randomly allotted into four equal groups and fed with a corn-soybean basal diet containing 22.6 mg·F/kg (control group) or same basal diets supplemented with 400, 800, and 1200 mg·F/kg (high F groups I, II, and III) in the form of sodium fluoride for 42 days. At 42 days of age, the serum F content was markedly higher in the three high F groups than that in the control group. From 28 to 42 days of age, the contents of serum total protein (TP) and albumin (ALB) were significantly lower in the three high F groups. From 14 to 42 days of age, the activities of alkaline phosphatase (ALP), alanine aminotransferase (ALT) and the creatinine (Crea) contents in the serum showed a marked increase in the three high F groups; aspartate aminotransferase (AST) activity and uric acid (Ua) content were significantly increased, and a significant increase in the content of malondialdehyde (MDA) along with marked decreases in the activities of total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), catalase (CAT), the glutathione (GSH) content and the ability to inhibit hydroxyl radical were observed in the high F groups II and III. In conclusion, F has accumulated in the blood circulatory system and dietary F in the range of 800 - 1200 mg/kg could significantly induce abnormalities of bone, liver and kidney, inhibit the synthesis of protein, enhance lipid peroxidation and disturb the antioxidative system of broiler chickens.
