In the available literature, there are limited data about the energetic value of insect-derived products. In particular, insect fat cannot be used in practical broiler nutrition due to the lack of precise apparent metabolisable energy (AME) value. Therefore, the present study aimed to investigate the AME and apparent metabolisable energy corrected...

Black soldier fly larva meal (BSFM) application as an innovative feed material has been developed in aquaculture nutrition. However, recent scientific literature is still lacking in the case of insect meal effects on different stages of salmonid fish, and the vast majority of research is focused on farmed Atlantic salmon. Therefore, the holistic ap...

Black soldier larva meal (BSFM) seems to be a competitive protein and fat source for widely used fish meal (FM) and fish oil. Because of the still present problem of overfished seas and oceans for feed purposes, even a low substitution of the mentioned feed materials could have a positive impact on the environment. Due to the specificity of salmon...

Simple Summary Today the poultry industry is facing mounting pressure to phase out chemoprophylaxis. One of the major threats to the poultry production is coccidiosis, a widespread parasitic disease, commonly controlled by in-feed coccidiostats. The use of immunoprophylaxis with the live anticoccidial vaccines instead of coccidiostats in broiler ch...

Different studies have shown that insect meals can partially or completely replace the fish and soya bean meals that are commonly used in aquaculture. However, information is lacking on the amino acid and fatty acid contents and digestibility of different insect meals. Moreover, we evaluated different proportions of insect diets and determined how...

We hypothesised that copper nanoparticles (NanoCu), because of their high physicochemical reactivity and bioavailability, could be used in much smaller quantities than bulk Cu, consequently reducing excretion of Cu into the environment. The objective of the study was to evaluate the effects of various levels of NanoCu on the development and growth...

Taking the macromarketing approach to insect food and feed, we study how the global insect marketing system is impacted by the global insect regulatory system. As an illustration, we study how the regulations of the European Union, USA, Canada and Australia impact marketing strategies of individual companies, and how company-level behaviour combine...
