A total of one day old 120 male broiler chicks (Ross 308) were utilized in this study. Chickens were fed a period of 42 days with experimental diets. Each dietary treatment was assigned to four replicates of 10 birds. Dietary treatments included a basal diet (control group); the MOS group (basal diet + 100 ppm Mannan oligosaccharide); and the COS group (basal diet+ 100 ppm Chitosan oligosaccharide). Total protein, albumin, total cholesterol, triglyceride, glucose, and plasma Cu and Zn levels were analyzed. At the end of the experiment, mean body weights (BW) were measured 2340.45, 2458.11, and 2325.38 g, respectively. Chicks fed with MOS group had a 5.03% higher BW than the control group. Dietary addition of MOS and COS had no significant effects in body weight gain, feed consumption, feed conversion ratio, carcass yield, and some blood parameters. Serum Cu level was significantly increased by dietary supplementation of MOS and COS compared to the control group. In conclusion, dietary supplementation of MOS and COS led to improved serum Cu level in broiler. Keywords : Broiler, Prebiotic, Performance, Mannan oligosaccharide, Chitosan oligosaccharide
