This study was conducted at a poultry farm of the Agriculture College, AL-Muthanna University to investigate the effect of using different ways to provide the Iraqi probiotic in some carcass characteristics. A total of 360 Ross 308 broiler chicks, one-day old were used and randomly allocated to six treatment, each was replicated three times (3 replicates per group; 25 chicks for each). These were T1(control group), T2(spraying Chicks with Iraqi probiotic at one day old), T3(Oral dosage of chicks with Iraqi probiotic at one day old), T4(injecting chicks with Iraqi probiotic in vent opening at one day old), T5(providing Iraqi probiotic with feed (1g/kg) from one day old to marketing age), and T6(providing Iraqi probiotic with drinking water (1g/L) from one day old to marketing age). Continous supplimentation of IP via drinking water or feed were significantly (P≤0.05) increased the dressing percentages and all primery carcass cuts, (breast,drum and thigh) percentages of broiler chicks. All Iraqi probiotics providing treatments gave significant higher results in all detected traits (P≤0.05), as compared control.
