Use of insects in poultry feed as replacement soya bean meal and fish meal in development countries: a systematic review

Interest in the utilization of insect for animal feeding is increasing due to the potential for more efficient in replacement for Soya bean meal and fish meal. A database was designed based on published papers reporting the use of insect as poultry feed replacing Soya bean meal and fish meal. An algorithm literature published from 1990 to 2021 based on the Preferred Reporting Items for systematic review and meta-analyses (PRISMA) protocols. The trim and fill method was employed to detect the number of potential missing studies and to adjust the overall effect size. All publication bias procedures were performed using XLstat. Reported the used several strain such as Black soldier fly (Hermetia illucens) help to increase the poultry performance. In conclusion, the use of insects as a sustainable protein rich feed ingredient in diets is technically feasible, and opens new perspectives in animal feeding.
