An experiment was conducted in order to investigate the impact of different levels of Probio-enzyme on some organ characteristics of broilers based on a completely randomized design as the factorial of 2×4 arrangement. Experiment included 8 treatment and also a control treatment including 270 broiler chickens. Experiment included 4 level of probio-enzyme amount (250, 500, 750, and 1000 g/ton) and also 2 usage duration (14, and 42 day). From obtained results, it is showed that usage duration of probio-enzyme had not significant effect on weight of pancreas (P>0.05), although usage duration of probio-enzyme as long as 42 days had the highest pancreas weight numerically (5.117 g). Probio-enzyme amount also had not significant on pancreas weight (P>0.05), however 1000 g/ton probio-enzyme resulted to the highest pancreas weight numerically (5.487 g). Meanwhile statistical differences between nine studied treatments for weight of pancreas were significant (P≤0.05). Amount of weight of pancreas in nine studied treatments were between 4.233-7.013 g. Among studied treatments, the highest level of pancreas weight belonged to treatment 3 (usage duration as long as 14 days, and probio-enzyme level as amount as 750 g/ton), and treatment 9 (usage duration as long as 42 days, and probio-enzyme level as amount as 1000 g/ton) remained at lower level than other treatments. Other treatments were between these treatments.
