The objective of this present study was to investigate the potentiality of prebiotics (mannan oligosaccharides-MOS and fructo-oligosaccharides-FOS) in replacement of antibiotic growth promoter and their relationship with physico-chemical indices, antioxidant and oxidative stability and carcass traits of broiler chickens meat. Accordingly, 240 day-old broiler chicks of uniform body weight divided in 6 treatment groups with 5 replicate each (5 × 6 = 30) having 8 birds in each replicate. Six corn based dietary treatments were formulated viz. T 1 (control diet), T 2 (T 1  + Bacitracin methylene di-salicylate @ 0.002%), T 3 (T 1  + 0.1% MOS), T 4 (T 1  + 0.2% MOS), T 5 (T 1  + 0.1% FOS), and T 6 (T 1  + 0.2% FOS). Significant ( p  < 0.05) increase in cut up part yields (%) and reduction in cholesterol and fat content in T 4 (0.2% MOS) group. The water holding capacity (WHC) and extract release volume (ERV) were increase ( p  < 0.05) in 0.1 or 0.2% MOS supplemented group. DPPH (1, 1-diphenyl-2-picrylhydrazy) was higher ( p  < 0.05) and lipid oxidation (free fatty acid and thio-barbituric acid reactive substances) was lower ( p  < 0.05) in T 4 group. The standard plate count (SPC), staphylococcus and coliform counts were decreased ( p  < 0.05) in T 3 or T 4 group. Thus, it can be concluded that mannan oligosaccharides (MOS) may be incorporated at 0.2% level in diet for improved physico-chemical indices, antioxidant and oxidative stability and carcass characteristics of broiler chickens meat and it may be suitable replacer of antibiotic growth promoter.
