Moradi Associate Professor, Department of Animal Science, Faculty of Agriculture and Natural Resources, Arak University, Arak, Iran Journal Article 2020 04 18 This study was performed to investigate the effect of dietary supplementation with Manna of Alhaji Maurum (Tarangabin) powder on performance, carcass traits, serum biochemistry, and jejunum histology parameters in broilers. The experiment was arranged in two separate sections, in the first section, 400, day-old male broilers (Ross 308) were randomly assigned to five treatments with four replicates. The dietary treatments consisted of the basal diet as control, control + 0.5% Manna in starter, control + 0.5% Manna in starter and grower, control + 1% Manna in starter, control + 1% Manna in starter and grower. In this experiment, supplementing the diet with 0.5% Manna in starter and grower periods increased the body weight of broilers at 10, 24, and 42 days of age (<em>P</em><0.05). The higher average daily gain was observed at 1-10, 11-24, and 1-42 days of age with 1% Manna treatment in starter and grower periods. The treatment of 1% Manna in the starter period had the greatest villus height that had a significant difference with control treatment (<em>P</em><0.05). It can be concluded that 0.5% Manna in starter and grower periods can be used as an additive for improving performance traits and 1% Manna in starter for jejunum morphology traits in broilers.
