Antioxidant enzymes status
The effects of POP supplementation in broiler chicken diet on antioxidant status are given in Table 3. //
There were no significant differences among dietary treatments in liver SOD and //
GSH-Px activities, while activity of CAT had a quadratic (Po0.05) response to supplementation of POP in the diet. //
Erythrocyte GSH-Px activity was linearly increased (Po0.05) in broiler chickens fed with diets supplemented by POP supplementation.//
No dietary treatment effect (P40.05) was observed in relation to erythrocyte SOD activity, however, the broiler chickens given 0.50% POP in diet had numerically greater erythrocyte SOD activity than other broiler chickens. //
There were no differences between dietary treatments in the TAC, however liver and serum MDA concentrations was linearly decreased (Po0.05) by POP supplementation.
// Also, broiler chickens fed on diets containing 0.75 or 1.00% of POP had numerically greater TAC concentration.
