Performance of broiler Japanese quail supplemented with single-strain and multi-strain bacteria

Abstract

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.
