Abstract

A small-scale feeding trial was conducted with 30 BUT Big 6 male turkeys (15 in each group) fed diets containing 0% or 15% distillers dried grain with soluble (DDGS) to investigate the effects of DDGS on meat quality, including fatty acid composition, and lipid peroxide and glutathione status of blood and liver. Quality parameters of breast meat did not differ between the treatments groups, except significantly higher shear force in the group fed diet-containing DDGS. DDGS inclusion did not cause significant changes in the chemical composition of breast muscle but revealed significantly lower proportion of myristic, palmitoleic and total saturated fatty acids, and higher proportion of linoleic and total polyunsaturated fatty acids. The higher proportion of polyunsaturated fatty acids of the diet containing 15% DDGS caused higher malondialdehyde content in blood plasma and red blood cell haemolysate, but not in liver or muscle homogenates. Consequently reduced glutathione content was significantly lower in blood plasma but higher in liver homogenate as effect of DDGS added to the diet, but did not differ in red blood cell haemolysate. Glutathione peroxidase activity showed similar changes as reduced glutathione. These results suggest that higher proportion of polyunsaturated fatty acids of the diet containing 15% DDGS resulted in higher malondialdehyde formation in blood, but not in liver and breast muscle because of the activation of the glutathione redox systemin liver.
