Abstract: The aim of the present study was to investigate the effect of probiotic, Acidifiers and their combination on carcass characteristics, internal organs, cuts performance and meat to bone ratio in broilers chicks. Two hundred and twenty, one day old unsexed broiler chicks (Ross308 strain) was used in this study. They were divided into four groups with five replicates (11 chicks per each). Group A fed the basal diet (control), group B fed the basal diet supplemented with probiotic (Bacillus subtilis) powder (1.6X 109 CFU/gm) at inclusion rate of 500gm/tone. Group C fed the basal diet supplemented with acidifiers; organic acids (Citric Acid, Fumaric Acid, D-L Malic Acid, Lactic Acid and Ortho-phosphoric Acid) at an inclusion ratefade 2kg/tone feed. Group D fed the basal diet supplemented with combination of Bacillus subtilis plus organic acids with the same inclusion rate as in groups (B) and (C) treatments. The addition of bacillussubtilis, acidifiers and their combination did not show any significant (P > 0.05) effect in regard to live body weight, net carcass, dressing percentage and the relative weight of internal organs.The bacillus subtilis supplemented group showed the highest breast weight with a significant (P < 0.05) difference as compared to acidifiers supplemented group. In addition, the inclusion of probiotic significantly affect the ratio of bone in the back bone cut and significantly (P < 0.05) increased skin ratio of breast cut.
