Popis: This study evaluated the performance and carcass characteristics of broiler chickens fed diets with varying substitution levels of fishmeal (FM) 0, 250, 500, 750, and 1000 g/kg DM with Napier grass protein (NGP). Treatment diets included T0 (control diet), T250, T500, T750, and T1000 to represent the different substitution levels. After the starter phase, birds were finished on a conventional fishmeal-based diet for 14 days. Feed intake, weight gain, and hot carcass decreased (P 0.05) to T500 birds (716.4 g/kg DM). Similarly, ME digestibility was highest in T0 birds (819.5 g/kg DM) although comparable (P > 0.05) to T250 birds and T500 birds. In contrast, T250 and T500 birds showed higher (P 0.05) in weight gains of T0 and T250 birds, although T250 birds had numerically higher weight gain compared with T0 birds. However, percentage change in weight gain in the finisher phase was influenced (P
