Table 3 Economic efficiency of insect meals as feed for animals
Insect type (dry) | Animal type | Insect meal inclusion | Conclusions | References |
|---|---|---|---|---|
Black soldier fly pupae | Broilers | 42% replacement of fishmeal and soybean meal | Resulted in a higher benefit − cost ratio with better return on investment compared to CPS | [56] |
Yellow mealworms | Broilers | 4–12% supplementation | The incremental levels of insect meal resulted in increased costs of poultry diets with reduced gross margins | [57] |
Black soldier fly larvae | Layers | 25 and 100% | Resulted in a positive benefit − cost ratio and return on investment. Hence, the inclusion levels were most suitable and cost-effective | [13] |
Full fat black soldier fly larvae | Fish | 10.50% inclusion | The inclusion level had the highest index of economic profitability | [14] |
Defatted black soldier fly larvae | Fish | Up to 100% replacement of fishmeal | Increased economic efficiency | [58] |
Black soldier fly larvae | Fish | 75% replacement of fishmeal | Significantly reduced feed costs and resulted in higher economic returns | [59] |
Black soldier fly larvae | Pigs | Up to 100% replacement of fishmeal | Insect meal inclusion had the same benefit − cost ratio and return on investment compared to fishmeal as a CPS in pig diets | [60] |
Black soldier fly larvae | – | 5 to 50% replacement of fish meal and soybean meal | Increased economic benefits | [29] |
