Abstract Insects have applications in many animal feeding programs for several reasons. First, increased emphasis on sustainable ingredients supports the use of insect-derived ingredients since insects have the capacity to sustainably re-purpose waste streams from food and feed production into nutrient dense ingredients. Second, many animals would naturally consume insects, thus incorporation into feeding programs may enhance animal welfare. Third, nutrient composition and availability is generally very high for insect-derived ingredients relative to requirements and formulae needs, although this varies with insect species, stage of development, feedstock on which they are raised and processing method. In addition to the essential nutrients that can be provided by feeding insect-derived ingredients, components including chitin and proteins and fatty acids with anti-microbial activity provide additional application in animal feeding programs. These concepts will be discussed relative to current knowledge about the primary insect species being reared at commercial scale: house crickets (Acheta domesticus), yellow mealworms (Tenebrio molitor), and black soldier fly larvae (Hermetia illucens).

Food And Feed

N-3 polyunsaturated fatty acids (n-3 PUFAs), and especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential compounds for human health. They have been proven to act positively on a panel of diseases and have interesting anti-oxidative, anti-inflammatory or anti-cancer properties. For these reasons, they are receiving more and more attention in recent years, especially future food or feed development. EPA and DHA come mainly from marine sources like fish or seaweed. Unfortunately, due to global warming, these compounds are becoming scarce for humans because of overfishing and stock reduction. Although increasing in recent years, aquaculture appears insufficient to meet the increasing requirements of these healthy molecules for humans. One alternative resides in the cultivation of microalgae, the initial producers of EPA and DHA. They are also rich in biochemicals with interesting properties. After defining macro and microalgae, this review synthesizes the current knowledge on n-3 PUFAs regarding health benefits and the challenges surrounding their supply within the environmental context. Microalgae n-3 PUFA production is examined and its synthesis pathways are discussed. Finally, the use of EPA and DHA in food and feed is investigated. This work aims to define better the issues surrounding n-3 PUFA production and supply and the potential of microalgae as a sustainable source of compounds to enhance the food and feed of the future.

AbstractHematopoiesis requires finely tuned regulation of gene expression at each stage of development. The regulation of gene transcription involves not only individual transcription factors (TFs) but also transcription complexes (TCs) composed of transcription factor(s) and multisubunit cofactors. In their normal compositions, TCs orchestrate lineage-specific patterns of gene expression and ensure the production of the correct proportions of individual cell lineages during hematopoiesis. The integration of posttranslational and conformational modifications in the chromatin landscape, nucleosomes, histones and interacting components via the cofactor–TF interplay is critical to optimal TF activity. Mutations or translocations of cofactor genes are expected to alter cofactor–TF interactions, which may be causative for the pathogenesis of various hematologic disorders. Blocking TF oncogenic activity in hematologic disorders through targeting cofactors in aberrant complexes has been an exciting therapeutic strategy. In this review, we summarize the current knowledge regarding the models and functions of cofactor–TF interplay in physiological hematopoiesis and highlight their implications in the etiology of hematological malignancies. This review presents a deep insight into the physiological and pathological implications of transcription machinery in the blood system.

While complex lipids of seaweeds are known to display important phytochemical properties, their full potential is yet to be explored. This review summarizes the findings of a systematic survey of scientific publications spanning over the years 2000 to January 2021 retrieved from Web of Science (WoS) and Scopus databases to map the state of the art and identify knowledge gaps on the relationship between the complex lipids of seaweeds and their reported bioactivities. Eligible publications (270 in total) were classified in five categories according to the type of studies using seaweeds as raw biomass (category 1); studies using organic extracts (category 2); studies using organic extracts with identified complex lipids (category 3); studies of extracts enriched in isolated groups or classes of complex lipids (category 4); and studies of isolated complex lipids molecular species (category 5), organized by seaweed phyla and reported bioactivities. Studies that identified the molecular composition of these bioactive compounds in detail (29 in total) were selected and described according to their bioactivities (antitumor, anti-inflammatory, antimicrobial, and others). Overall, to date, the value for seaweeds in terms of health and wellness effects were found to be mostly based on empirical knowledge. Although lipids from seaweeds are little explored, the published work showed the potential of lipid extracts, fractions, and complex lipids from seaweeds as functional ingredients for the food and feed, cosmeceutical, and pharmaceutical industries. This knowledge will boost the use of the chemical diversity of seaweeds for innovative value-added products and new biotechnological applications.

Abstract This chapter explores the nutritional composition of insects and the potential benefits and drawbacks for their inclusion into pet, poultry, pig, ruminant and aquatic animal feeds. Six species are most commonly described for use in animal feed, namely black soldier fly (BSF; Hermetia illucens) larvae and prepupae, yellow mealworm (YM; Tenebrio molitor) larvae, superworm (SW; Zophobas morio) larvae, lesser mealworm (LM; Alphitobius diaperinus) larvae, house fly (HF; Musca domestica) larvae and house crickets (HC; Acheta domesticus). The nutritional composition, variability observed due to manipulation of feed source, age, developmental stage and suitability for inclusion into animal feed are compared.

Production Knowledge

In South Africa, livelihoods of smallholder cattle farmers are constrained by a lack of appropriate production knowledge, climate change, inadequate support services, societal inequity, irrelevant pro-poor policies and inappropriate delivery of improved livestock technologies. A transdisciplinary team of local and international researchers conducted a workshop to explore opportunities and constraints to the delivery of a beef cattle custom feeding programme in Eastern Cape Province using participatory approaches, including visioning exercises. The main challenges to the cattle custom feeding programme reported by producers included lack of cattle production skills, lack of technical knowledge on feed production, limited funding and inconsistent cattle feed delivery. Participants envisioned a portfolio of locally based solutions that included prioritization of local feed production, identification of sustainable support networks, establishment of a communal herd to cover feeding centre’s overhead costs and creation of a knowledge exchange platform for farmers. In addition, participants attempted to strengthen knowledge transfer among stakeholders through the development of an online site for knowledge exchange. Overall, the participatory approaches adopted empowered participants to freely express their opinions and openly share knowledge and experiences regarding common challenges and opportunities associated with delivery of a beef cattle custom feeding programme.

Innovative Techniques

This Special Issue of Foods explores different aspects of how insects can be used as a novel resource for food and feed. Some contributions deal with questions of acceptability and legality, others tackle problems related to innovative techniques in processing and marketing food, and yet another group of papers highlights the use of insects and their bio-active products in the context of promoting human health. The collective aim of the contributions by the researchers from at least 20 countries is to examine whether the use of insects—be it for food, feed, or therapeutic purposes—has a future. We conclude that positive aspects undoubtedly exist regarding the nutritional and pharmacological value of various insect species but that environmental and bio-functional issues could even outweigh the nutritional value of food insects.

The Impact

Given a growing global human population and high pressures on resources, interest in insects as a source of protein for human food (entomophagy) and for animal feed is growing. So far, the main issues discussed have been the embedded technical challenges of scaling up the production. The use of insects as a major human food and feed source is thought to present two major challenges: (1) how to turn insects into safe, tasty socially acceptable feed and food; and (2) how to cheaply yet sustainably produce enough insects? Entomophagy, however, as any utilisation of animals and the rest of nature also entails ethical issues – both regarding the impact on human health, the environment and climate change and regarding production methods such as intensification and biotechnology. The aim of the paper is to give a systematic overview of ethical aspects embedded in the notion of utilising insects as protein providers in the Western food and feed production chains. We identify five areas where ethical questions are especially pertinent: environmental impact, human and animal health, human preferences and social acceptability, animal welfare and finally broader animal ethics issues. Especially the latter two are more scantly dealt with in the literature. This part of the review will therefore contain suggestions for ethical issues that should be examined closer.
