Abstract This study was conducted to evaluate the dietary effects of chromium methionine (Cr-Meth) chelate on growth performance, oxidative stress parameters, blood biochemistry, and carcass traits broiler chickens. An experiment 34,000 1-day-old straight-run chicks (Indian River; 42.0 ± 0.03) at a commercial farm. The were divided randomly into 3 groups; first group contained 17,000 birds, which used as control, whereas second third groups consisted 7000 10,000 respectively, with 5 replicates per group. A completely randomized design used. birds fed experimental diets containing graded levels Cr-Meth chelate: 0 (control), 50, 100 g/ton. compound (0.4%) chelated methionine, it supply 200 400 ppb Cr for 50 g/ton feed, respectively. Growth performance indices (body weight, body weight gain, feed intake, conversion ratio) measured throughout experiment. At end experiment, 10 treatment slaughtered, yield relative internal organs determined. Also, samples taken analyzed glutathione peroxidase activity, malondialdehyde, ALT, AST, total protein, albumin, glucose, urea, creatinine, triglycerides, cholesterol. It found that improved ratio broilers. Moreover, reduced mortality rate birds. can alleviate status by increasing plasma activity reducing serum malondialdehyde level. observed indices, rate, parameters better than inclusion rate. Supplementation increased protein level, but cholesterol, triglyceride concentrations in serum. In addition, abdominal fat percentage birds’ carcass. Therefore, be included broilers ppb, higher concentration more effective lower one. So, recommended use improve productive reduce
