Effect of dietary inclusion of black soldier fly larvae (Hermetia illucens) on broiler performance: A meta-analysis

Abstract

Black Soldier Fly (BSF, Hermetia illucens) is an insect species that potentially can be used as a protein source for broiler nutrition. This study aimed to evaluate different inclusion level of BSF on broiler performance and blood metabolites by integrating various data from related studies using meta-analysis. Total of 12 studies that comprised of 31 data points were integrated in the database. Parameters observed included Live Weight (LW), Average Daily Gain (ADG), Daily Feed Intake (DFI), Feed Conversion Ratio (FCR), blood metabolites, and carcass proportion. The database was statistically analyzed by using mixed model method. Different studies were considered as random effects, and the level of BSF was treated as fixed effects. The model statistics used were the p-values and the Akaike information criterion. The significance of an effect was stated when its p-value was < 0.05. The results revealed that BSF feeding had significant linearly reduction effect on LW, ADG, and FCR of broiler (P < 0.05) and significant linearly increase effect on DFI and carcass proportion. However, BSF did not significantly affect on blood metabolites of broilers. It can be concluded that BSF negatively affect the performance of broiler.

Carcass and meat quality traits of IPB D1 chicken on black soldier fly larvae (BSFL) dietary inclusion

“…In general, in this study BSFL dietary inclusion had no effect on the carcass and cut-up percentage. Several studies conducted in broiler chicken found that supplementing with BSF meal had no effect on the carcass percentage of broilers [16].…”

“…Total meat protein from groups T1 and T2 is similar to T0 groups, although BSFL is known as a high protein source feedstuff, but BSFL meal has a lot of chitin, which is indigestible and can reduce protein digestibility. The chitin in the exoskeleton of HI larval Chitin was shown to have a detrimental impact on protein digestion [16].…”

Edible insects: Challenges and prospects

“…Chodová and Tůmová (2020) reviewed a number of studies, and found that insect meals can have a positive influence on growth of chickens without negative impact on carcass and meat quality characteristics. Nayohan et al (2022) reviewed 12 studies concluding that feeding of broilers with black soldier fly negatively affect their performance. This is probably the reason that optimal inclusion levels need to be established for products from different insect species and per poultry species (Dörper et al 2021).…”
