Live larvae fed to poultry has shown to provide good nutrients and bioactive compounds with positive effects on bird's health. However, trials on chicken reared for meat consumption are still scarce. A total of 240 Label naked neck (LNN) birds were reared from 21 to 82 days of age, and four experimental groups (10 birds/pen, 6 replicates/treatment) were considered according to the birds’ gender and larvae provision. Experimental groups were fed 10% supplementation of black soldier fly (BSF) live larvae based on the daily feed intake. Birds (12/diet, 2 birds/pen) were slaughtered according to the standard EU regulations. Following storage at 4°C for 24 h, breast fillets were excised, vacuum packaged and transported to the laboratory for analysis. Vacuum packed breasts were cooked in a water bath at 75°C for 45 min, then breast color and drip loss were measured. Sensory descriptive analysis was performed, in duplicate, by 11 trained judges, experts in sensory evaluation with a specific software for sensory data acquisition, (FIZZ Biosystèmes), using a nine points intensity scale. Results were elaborated by a statistical analysis using R software. Color measurement, drip loss percentage and sensorial profiles were analyzed through the ANOVA and post hoc test (Tukey’s HSD). No significant differences were found in mean percentages of drip loss while color measurement showed only differences based on chicken gender and only for the b* (yellowness) parameter that resulted higher in females. Concerning sensory evaluation, no significant differences were found. In conclusion, results highlighted that a dietary 10% supplementation of BSF live larvae did not affected sensorial quality of breast fillets of LNN chickens reared in an organic production system.
