The purpose of this study was to evaluate the mortality rate, weight gain, and protein, lipid cholesterol, and total amino acid contents in processed-sulfur-diet chicken meat. Also investigated were the antioxidant activity and glutathione content of blood plasma. The mortality of the processed-sulfur-diet chickens was relatively reduced, and their weight increased compared to the normal-diet chickens. Although the glutathione content decreased in the processed-sulfur-diet chicken blood plasma, the antioxidant activity increased compared with the normal-diet chickens. Also, there was no difference in the total cholesterol contents of the blood, but the level of HDL cholesterol increased while that of LDL cholesterol decreased. Furthermore, there were no changes in the total amino acid and protein contents, but the fat content was significantly reduced. As no toxicity was found in the DT 40 cells in the MTT assay, it can be concluded that dietary sulfur in chicken feed can improve the quality of poultry products.
