The present study aimed to evaluate the effects of Protaetia brevitarsis seulensis (PBS) powder dietary inclusion levels on the antioxidant activities of broiler breast meat during storage. A total of 270 Arbor Acres broiler chicks were randomly allocated to three treatments (3 replicates with 30 birds per pen), fed diets with inclusion of 0%, 0.5% or 1% PBS powder, in a completely randomized design. After slaughtering, samples were packed and stored at 4°C for later analysis of broiler breast meat. Antioxidant analysis included measurement of pH, thiobarbituric acid reactive substances (TBARS), and 1, 1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical scavenging activity. All samples were measured at storage days 0 and 7 as three replicates. For breast meat, changes were observed in pH, TBARS values, and DPPH radical scavenging at storage days 0 and 7 ( p < 0.05), except for TBARS values at storage day 0. Overall, the addition of PBS powder resulted in lower TBARS values and higher DPPH radical scavenging in broiler breast meat during storage. Based on these results, it can be concluded that the addition of 0.5% and 1% PBS powder to broiler diets was effective at reducing lipid oxidation during storage, which could be related to the subsequent lower meat pH.
