Abstract

This study evaluated the impact of rice bran storage duration on broiler chicken growth performance and meat quality. Ninety-six male Cobb 500 chicks were randomly assigned to four groups, each receiving one of four isonitrogenous and isoenergetic diets: a control corn-soy diet or diets containing rice bran stored for less than 24 hours, 1 week, or 30 days. Growth performance was monitored, and after 30 days, carcass traits, digestive organ measurements, and meat quality parameters were assessed. Diets containing rice bran stored for 1 week and 30 days exhibited elevated Thiobarbituric acid reactive substances (TBARS) values, indicating increased lipid oxidation. Notably, broilers fed rice bran stored for 30 days showed reduced (P
