Effects of Selenium, Copper and Magnesium on Antioxidant Enzymes and Lipid Peroxidation in Bovine Fluorosis

Abstract

Eight 6-7 year-old non-high fluoride beef cattle from Yongning city, Ningxia, China, and foodstuff was produced in non-high fluoride area. Thirty-two 6-7 year-old beef cattle, which were raised by farmers in Guangwu county Qin Tongxia city, Ningxia, China, were selected at natural high fluoride area, and randomly divided into four groups with eight cows being fed with local fluoride foodstuff. The groups were as follows: (1) high fluoride control group (HFC), (2) supplemented with 0.25 mg/kg selenium (sodium selenite)(HFSe), (3) supplemented with 15 mg/kg copper (copper sulfate)(HFCu), (4) supplemented with 0.25 mg/kg selenium+15 mg/kg copper +1 mg/kg magnesium (magnesium sulfate) per day for 83 days, respectively, and
