Effect of chelated and inorganic zinc, selenium and chromium on antioxidant status, biochemical and production parameters in broiler

In the present investigation we explore the use of organic and inorganic zinc, selenium and chromium to modulate antioxidant defense system, biochemical status and enhance production response of Broiler. Total 312 day old Cobb broiler chicks were used in the experiment. The results indicate that mean plasma superoxide dismutase, glutathione peroxidise and glucose concentration were non-significantly different in all groups. Significantly (p<0.05) higher mean plasma catalase concentration and TBA value was found in T13 and control group respectively. Mean plasma total protein, albumin and globulin were significantly (p<0.01) higher in organic Zn, Se and Cr (T13) followed by organic Cr (T10) supplemented group. Mean body weight gain, feed intake, FER and PI were significantly (p<0.01) higher in organic Zn, Se and Cr (T13) followed by organic Se (T7) supplemented group. In the present investigation organic Zn, Se and Cr supplementation showed systemic effects with a better biochemical status, which could be translated into better production performance and lower mortality.
