State-of-the-art on use of insects as animal feed.

Insects are considered as a potential substitute for fishmeal (FM) and soybean meal (SBM) in feeding mixtures for poultry diets. The intent of this paper is to appraise the current work relating to...

Recent advances in role of insects as alternative protein source in poultry nutrition

This chapter assesses the potential of insects as feed in livestock and aquaculture. Currently aquaculture and livestock feeding causes important enviromental problems that will increase in the future due to the growing world population and the corresponding increase in need of foodstuffs of animal origin. Insects could be an alternative and sustainable protein for animal feed. This chapter analyzes the evolution of this concept based on the number of publications and their distribution by country and species. We gather and evaluate the main experiments using insects as feed in different species of livestock and fish. Also discussed are: the benefits and nutritional constraints of insects from the point of view of animal feed, the nutrient contents regarding other protein sources, and the role of insects in animal welfare and their safety as feed ingredients. Finally, this chapter discusses the promising opportunities for research, such as environmental enrichment, ecological implications, and the improvement of nutritive values.

Brief Summary of Insect Usage as an Industrial Animal Feed/Feed Ingredient

The increasing, worldwide demand for fishmeal due to the development and expansion of the poultry industry raises the market price of fishmeal. Insects can be a perfect alternative as a source of protein in poultry diets due to the high percentage of protein (55–70%) they contain, along with a highquality profile of amino acids. In addition, insects greatly improve chicken meat quality and decrease the cost of production. However, the use of insects as a source of protein in animal diets is still prohibited due to different feed safety and quality laws. Insect protein is only allowed in fish or shellfish feed in Europe; however, the purified fat extracted from larvae is allowed to be used in animal diets. In conclusion, insects have proven to be a sustainable source of protein, are of an attractive quantity and quality, and have acceptable nutritive properties. The use of insects as a potential protein-rich feed ingredient in diets is practical and creates new perspectives in mono-gastric animal feeding.

Insect Meal as a Source of Protein in Animal Diet

Denna studie utvarderar den kemiska sammansattningen hos kambodjanska syrsor (Teleogyrus testaceus) uppfodda pa fyra olika dieter. Syrsor fran en tidigare studie (Miech et al., 2016) om tillvaxt och overlevnad anvandes i studien. Aminosyrakomposition, mineralinnehall, vikt och storlek analyserades. Syrsor uppfodda pa Cassava-plantor var tyngre och inneholl hogre nivaer av flera essentiella aminosyror an kontrollgruppen som fotts upp pa kommersiellt kyckling-foder. Mineraler kopplade till de vanligast forekommande minerala bristsjukdomarna hos manniska (sasom jarn, magnesium och zink) skilde sig inte mellan grupperna.
 
Studien undersokte ocksa mojligheterna att anvanda datortomografiteknik (CT-skanning) for att uppskatta storleken och volymen pa en syrsas gastrointestinalkanal. Det var mojligt att producera en bild av en del av gastrointestinalkanalen med hjalp av kontrast, men mer forskning ar nodvandig for att utveckla denna metod, om den skall anvandas for att berakna volymen av hela gastrointestinalkanalen pa flera olika syrsor eftersom det var en tidskravande metod. 

Som en sista del av studien skulle mojligheten att paverka storleken och volymen av en syrsas gastrointestinalkanal med hjalp av olika dieter undersokas. Detta sista experiment kunde inte fullfoljas pa grund av hog mortalitet bland syrorna som anvandes i studien.

The impact of feed and diet on crickets’ nutritional value and anatomy

The nutritional value of Acrida cinerea were analysed.The influence of Acrida cinerea replacing Peru fish meal on growth performance of broiler chickens was investigated The results showed that feed replacing 20% and 40% Peru fish meal with Acrida cinenea for broiler chickens in growth rate and feed consumption tended to be similar to that resulting from feeding a normal contain diet The study suggests that the Acrida cinerea may replace Peru fish meal partly
