ArticleState-of-the-art on use of insects as animal feed 2014
Also available in:
No results found.A 60-70% increase in consumption of animal products is expected by 2050. This increase in the consumption will demand enormous resources, the feed being the most challenging because of the limited availability of natural resources, ongoing climatic changes and food-feed-fuel competition. The costs of conventional feed resources such as soymeal and fishmeal are very high and moreover their availability in the future will be limited. Insect rearing could be a part of the solutions. Although some s tudies have been conducted on evaluation of insects, insect larvae or insect meals as an ingredient in the diets of some animal species, this field is in infancy. Here we collate, synthesize and discuss the available information on five major insect species studied with respect to evaluation of their products as animal feed. The nutritional quality of black soldier fly larvae, the house fly maggots, mealworm, locusts-grasshoppers-crickets, and silkworm meal and their use as a replacement of soym eal and fishmeal in the diets of poultry, pigs, fish species and ruminants are discussed. The crude protein contents of these alternate resources are high: 42 to 63% and so are the lipid contents (up to 36% oil), which could possibly be extracted and used for various applications including biodiesel production. Unsaturated fatty acid concentrations are high in housefly maggot meal, mealworm and house cricket (60-70%), while their concentrations in black soldier fly larvae are lowest (19-37%). Th e studies have confirmed that palatability of these alternate feeds to animals is good and they can replace 25 to 100% of soymeal or fishmeal depending on the animal species. Except silkworm meal other insect meals are deficient in methionine and lysine and their supplementation in the diet can enhance both the performance of the animals and the soymeal and fishmeal replacement rates. Most insect meals are deficient in Ca and its supplementation in the diet is also required, especially for growi ng animals and laying hens. The levels of Ca and fatty acids in insect meals can be enhanced by manipulation of the substrate on which insects are reared. The paper also presents future areas of research. The information synthesized is expected to open new avenues for a large scale use of insect products as animal feed. -
Book (stand-alone)Looking at edible insects from a food safety perspective
Challenges and opportunities for the sector
2021Also available in:
No results found.While insect consumption by humans or entomophagy has been traditionally practiced in various countries over generations and represents a common dietary component of various animal species (birds, fish, mammals), farming of insects for human food and animal feed is relatively recent. Production of this ‘mini-livestock’ brings with it several potential benefits and challenges. The objective of this document is to provide the reader with an overview of the various food safety issues that could be associated with edible insects. The intended audiences of this publication are food safety professionals, policymakers, researchers, insect producers as well as consumers. The regulatory frameworks that govern production, trade and consumption of insects in various regions are discussed. The document ends with elucidating some other major challenges, such as consumer acceptance and scaling up production, that the edible insect industry would need to overcome to have a more global reach. -
DocumentLa Contribution des Insectes à la Sécurité Alimentaire, aux Moyens de Subsistance et à l'Environnement 2013L'entomophagie est la consommation d'insectes par les humains. L'entomophagie est pratiquée dans de nombreux pays du monde entier, mais principalement dans certaines régions d'Asie, Afrique et Amérique latine. Les insectes complètent les régimes alimentaires d'environ 2 milliards de personnes et ont toujours fait partie de l'alimentation humaine. Cependant, c'est seulement récemment que l'entomophagie a capté l'attention des médias, instituts de recherche, chefs cuisiniers et autres membres de l 'industrie alimentaire, législateurs et autres institutions s'occupant d'alimentation humaine et animale. Le Programme de la FAO sur les insectes comestibles examine également le potentiel des arachnides (par ex. les araignées et scorpions) pour l'alimentation humaine et animale, bien que par définition, ce ne soient pas des insectes.
