Effect of vitamins E plus C and taurine on the oxidative state of DNA in the liver of growing pigs

摘要

Growing pigs (n=21) at an initial liveweight of 30 kg were divided into three groups of 7 animals each and housed in individual cages for 100 days. The pigs were fed with similar diets (13.5 MJ ME and 178 g crude protein/kg) but with different additions of vitamins C+E and taurine. The antioxidative vitamins E and C supplied to diets with high energy concentrations (containing lard) can act as pro-oxidants on liver DNA in growing pigs. Taurine decreased the concentration of products from nucleotide oxidation, but in the presence of vitamin E and C, promoted hepatocyte lesions.
