“…Nutritional quality Insects are regarded as an interesting alternative protein source for feed and are expected to be increasingly used in Pinotti, Giromini, Ottoboni, Tretola and Marchis Europe as a replacement for animal-derived proteins, especially in aquaculture (Spiegel et al, 2013;Jo and Lee, 2016), although they also have potential for other species (van Raamsdonk et al, 2017) and as a fat/energy source (Wang and Shelomi, 2017;Biasato et al, 2017;Schiavone et al, 2018). Their nutritional and technological properties are linked to the species, rearing system adopted and especially to the substrate used (Veldkamp and Bosch, 2015;Spranghers et al, 2017;Ottoboni et al, 2017a;Meneguz et al, 2018). Among the species reared, the BSF (Hermetia illucens), common housefly (Musca domestica) and yellow mealworm (Tenebrio molitor) have the highest potential for large-scale production (Veldkamp and Bosch, 2015).…”

“…The main concern in this context is that hat intensive insect rearing with high insect densities is likely to be associated with health issues, since insects can serve as reservoirs for pathogens as observed in conventional livestock production (Kelemu et al, 2015). Several studies, however, have highlighted that a safety margin exists when good mini-livestock practices are adopted as well as the post-harvest biomass treatment and processing (Boccazzi et al, 2017;Ottoboni et al, 2017a). Insects for feed are processed with their intestinal content, which can harbour different species of transmissible microorganisms.…”

The increasing global need to find alternative protein/energy sources has triggered research in the field of non-conventional feed ingredients, with insects and former foodstuffs being the most promising. Insects contain high level of protein and fat, whereas former foodstuffs contain high energy in the form of carbohydrates and fats; therefore, both should be considered as promising alternative feed ingredients for livestock production. In addition to the nutritional value, they also represent a way by which food waste biomasses/streams can be upgraded to valuable feed ingredients. This review outlines the main nutritional and safety issues of insects and former foodstuffs, and also considers the legal framework involved. The importance of the type of insect metamorphosis and tailored substrates that could lead to the production of a premium feed is also described. This is also the first time that a review discusses the nutritional quality of former foodstuffs. Energy and the main nutrient content of former foodstuff are compared with the composition of common cereals as the principal energy sources in animal feed. For both ingredients a critical review of the safety issues is provided. Based on the current data available, both insects and former foodstuffs have an excellent potential use as alternative feed ingredients for livestock production. When produced in line with the criteria set by major feed/food authorities, they are characterized by high quality and safety standards. This makes them comparable to other feed materials and ingredients currently available on the market, although their full nutritional, functional, safety and sustainability evaluation cannot be considered complete.

“…Composition -Insects are natural preys and components of the diet of many farmed animals, but their nutritional value greatly varies according to the insect species and the rearing substrate (Gasco et al 2019a;Koutsos et al 2019). Though being considered an interesting alternative protein source for feed, the nutritional properties of insects depend on the species, rearing system and especially on the substrate used for their growth (Veldkamp and Bosch 2015;Ottoboni et al 2017a;Meneguz et al 2018;Danieli et al 2019).…”

This paper reviews current knowledge on two feedstuffs, that is, insect meal and fish by-products, as alternatives to conventional animal protein sources. After an introductory part that highlights the need for sustainable development of animal production, the alternative protein sources are discussed. In particular, after providing some indications on their production and supply focussing on EU, a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis was performed to identify the key factors that could help or impair the development of both protein sources production sectors. Finally, future perspectives are presented. The use of processed animal proteins derived from insects in farmed fish feeding is recognised by the EU legislation that authorises the use of proteins from seven insect species and the allowed substrates to rear insects. Insects have several advantages in nutritional value and the amino acid composition of their proteins generally meet animal requirements for good growth and health. The SWOT analysis indicated that insect meals can be considered as feed functional ingredients with beneficial properties that depend on the insect species, rearing system adopted, and the substrate used for their growth. Insects are expected to be increasingly used as a replacement for conventional animal-derived proteins, especially in aquafeeds. In the section regarding fishery and aquaculture by-products, the potential use of raw materials obtained during seafood processing is discussed. Peptides and amino acids recovered from as hydrolysed proteins can be used in animal feeds to partially substitute conventional protein feedstuffs thus providing nutrients, bioactive compounds and feed additives for animals. The SWOT analysis identified opportunities and weaknesses. Both the alternative protein sources are promising alternative feed ingredients for livestock production. HIGHLIGHTSThe sustainable development of animal production sector needs alternative protein sources for feeds formulation. Insects and fishery-and aquaculture by-products represent optimal alternative protein sources. A SWOT analysis has identified the key factors for the development of both protein sources production sectors. ARTICLE HISTORY

The experimental studies were carried out in the Rostov region of Russia in 2019. Three variants of grinded wheat grain mixed with biomass of black soldier fly larvae with raw animal material content of 10, 12.5 and 15 % by mass were extruded at varying temperature. The content of amino acids in raw material and finished extrudate was determined. It has been established that the feed mixture containing grinded wheat grain and biomass of black soldier fly larvae can be successfully extruded at the temperature of 121-135 ºC. As the extrusion temperature rises in the range of 115º-140 ºС, the content of amino acids in a finished extrudate decreases. Change in larvae content in the feed mixture does not affect the nature of the correlation between the amino acids content in the extrudate and the extrusion temperature and process behavior. It has been found that with increasing temperature the amino acids content in the extruded feed decreases with an accelerated velocity irrespective of the insect biomass content. The rational temperature range for extrusion of feed mixture containing grinded wheat grain and larvae biomass was determined within 121-127 ºC. This range provides no more than 30 % decrease in indispensable amino acids content in the extrudate. The extruded feed containing 15% of insect larvae biomass contains 9.6±0.13 % of amino acids, including 4.38±2.01 % of indispensable amino acids. Extrusion of larvae biomass mixed with grain of cereal crops is considered to be a promising direction for improving production of feed for fish and farm animals.
