The growth performance of six-hundred (600) growing Japanese quails, distributed according to completely randomized design into 3 treatment groups(5 replicates/treatment of 40 birds each) was recorded to evaluate the effect of feeding single and multi-strain bacteria. The experiment lasted for 4 weeks. Significant(P≥0.05) results were observed regarding weight gain, folds of weight gain and FCR in the group fed multi-strain bacteria. Improved(P≥0.05)total tract protein digestibility was detected in birds fed the diet containing multi-strain bacteria. Higher blood glucose level (P≥0.05)was noticed in the group fed with single-strain bacteria. Blood cholesterol level inbirds fedsingle and multi-strain bacteria was found higher (P≥0.05). Enhanced(P≥0.05)carcass characteristics and dressing percentage were recorded in birds fed with single strain bacteria. Superior (P≥0.05) weights of bursa and spleen wererecordedin the group fed with single-strain bacteria.
