Investigation of breast meat traits of broilers fed different amounts of Hermetia illucens and Protaetia brevitarsis seulensis powder

Abstract

AbstractThe aim of this study was to investigate the effects of different levels of Hermetia illucens (HI) and Protaetia brevitarsis seulensis (PBS) powder on breast meat of broilers during storage. A total of 400 1‐d‐old Arbor Acres broilers were randomly divided into four treatments; each treatment group included four replicate pens with 25 birds per pen. Broilers were fed basal diets supplemented with 0.5%, and 1% HI powder or 1.5% PBS powder or only basal diets without HI or PBS. Traits such as meat quality, color, and antioxidant effects were evaluated. The different levels of HI and PBS powder did not enhance meat quality and color during storage. On day 0, thiobarbituric acid reactive substance (TBARS) values were not significantly affected by different levels of HI and PBS (p > 0.05). However, a significant decrease in TBARS values on day 7 was observed with 0.5% HI and 1.5% PBS treatment compared to values obtained with other treatments (p < 0.05). The reduction in TBARS values with 0.5%, and 1% HI or 1.5% PBS treatments on day 7 was 75.4%, 63.1% and 76.9%, respectively. Between the different levels of HI and PBS treatment, no significant differences in 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical scavenging were observed after 7 days of storage. However, addition of HI and PBS powder to broiler diets had a significant effect (p < 0.05) on DPPH radical scavenging in broiler breast meat on day 0. These results indicate that addition of 0.5% HI and 1.5% PBS to broiler diets improves the antioxidant activity of broiler breast meat during storage.
