Broiler chickens were fed diets containing 0, 210, 420 or 840 mg vitamin C kg-1 feed from 10 to 42 days of age. The diets contained 13.6% fat and 87.7% unsaturated fatty acids. Activity of creatine-kinase (CK) and glutathione peroxidase (GSH-Px) decreased with increasing levels of dietary vitamin C. No statistical difference between groups was found with respect to the concentration of vitamin E or lutein in plasma, but chickens fed diets containing 420 or 840 mg vitamin C kg-1 feed had a significantly higher plasma concentration of retinol and ss-carotene compared with chickens fed diets containing 0 to 210 mg vitamin C kg-1 feed. A considerable erythrocyte haemolysis in vitro was demonstrated in all groups and increased with increasing dietary level of vitamin C. The unsupplemented group had a lower concentration of fatty acids expressed as a percentage in extracted fat compared with the vitamin C supplemented group. No influence of dietary vitamin C on the concentration of antioxidative vitamins in the liver, the breast and the thigh muscle was observed. Nor did vitamin C influence the energy metabolism of breast and thigh muscle. Vitamin C did not affect the oxidative stability of the meat under chill and freezer storage. |
