This study sought to assess the impact of phytase super dosing on broiler carcass characteristics. The experiment consist of 168 straight run broiler chicks were randomly allocated into four dietary treatment groups, each comprising six replicates with seven birds per replicate. The dietary treatments were: one positive control diet without phytase (Group I) and three low phosphorus diets supplemented with phytase at 500, 2500, and 5000 FTU/kg feed (Groups II, III and IV, respectively). The feeding trial was conducted for 35 days. At the end of the experiment, two birds per replicate were slaughtered for carcass trait analysis. Birds receiving higher phytase levels (Groups III and IV) showed significantly (p<0.05) greater body and carcass weights. These findings suggest that supplementing super doses of phytase in low-phosphorus diets can enhance growth performance and carcass characteristics in broiler chickens.
