Effects of black soldier fly larvae as feed component on poultry performance and behaviour

Summary

In recent years, insects such as black soldier fly (BSF) larvae have gained importance as a feed ingredient for poultry such as broilers and layers. Rightful so, as BSF larvae contain valuable nutrients such as protein and fat, suitable to replace unsustainable plant protein sources in poultry diets. Feed conversion ratios in both broilers and layers was improved by feeding live BSF larvae, while feed conversion ratios in broilers were also improved when BSF meal and oil were combined in the broiler diet. In addition, poultry are very eager to eat insects, also in nature, bugs and larvae are part of their natural diet. Both broilers and laying hens were influenced by the provision of live larvae, which triggered the display of feed related activities while reducing resting behaviour. The thesis gives insights about the product specific strengths of BSF live larvae, meal and/or oil in poultry diets.
