In 2017, a book was published entitled ‘Insects as food and feed: from production to consumption’ (Van Huis and Tomberlin, 2017). However, the sector of insects as food and feed is developing so quickly that an update seems appropriate. This book ‘Advancement of insects as food and feed in a circular economyy’ is a reprint of the Special Isse in Open Access in the Journal of Insects as Food and Feed. All chapters dealt with relevant topics related to insects as food and feed, and most of the content of the articles is different from the 2017 book, reflecting developments in the field.
Interactions between society, biodiversity and water in a humid tropical forest
This book examines interactions between human communities and the global biodiversity that is sheltered by the Salonga National Park. While not being a review of research that has been on-going in the Salonga National Park over several years now, the book takes a bird-eye perspective to look at how the forests, waters and species that occur in the wider Salonga landscape interact to give birth to what the Salonga National Park is. As such, the book treats of the Salonga’s wildlife, its forests and waters, and the Salonga National Park’s contemporary human history, within the regional framework.
Universal Model of Water Resources Management
The conservation of water resources together with environment protection will be a challenge for the European Union within the 21st century. Water management nowadays involves the cooperation of farmers, societies, industry and public administration. The solution based model of water protection in this book describes the creation of local water partnerships by local actors and stakeholders for the management of local water resources. These local water partnerships will enable the integration of the local community to comprehensively solve problems related to water security, while also cooperating with neighbouring partnerships. The local water strategy is based on local needs and priorities with reference to regional, national and global objectives. This strategy also provides for environment and species protection, as envisioned by the New Green Deal and the current EU actions to make the key economic sectors more resistant to climate change. The model for water protection can also be used to reduce the carbon footprint and environmental transformation within Europe.
A comprehensive guide to its aetiology, impact and wider significance in pig management
Volume Editors: and
This book provides a comprehensive overview of the issue of tail biting in pigs, one of the most significant welfare and economic problems in the pig industry. With contributions from renowned experts in their fields, it is an essential resource for both scientists, and industry stakeholders. Key topics include the evolutionary roots of the disorder, internal and external risk factors, methods that can be used to address the issue, including human behavioural change, and the wider economic, and ethical considerations. Finally, evidence is provided as to how an intact tail can be used as an ice-berg indicator for overall pig welfare.
A journey through the world of food taboos and food cultures
Adel den Hartog shows how complex the food choices of humans have been for millenia. Those who wonder why we eat what we eat, will find out practicalities, such as availability of products, transportation and costs, but also physiological, cultural, geological, and psychological factors matter. Den Hartog points out the importance of access to food for individuals and groups, and the influence of their socio-economical position. Can someone be convinced to eat something that they perceive as inedible? This book gives many examples of our limited flexibility, whether caused by an intolerance for genetical reasons, or because we simply did not know the food and want to keep it that way. Food habits are slow to respond to interventions, but these days, a meatless meal is no longer a sign of poverty. The book will attract the culturally interested reader. It can be used as a handbook for those who want to understand the background of our eating habits. The knowledge in this book can be used for a large range of interventions when it comes to food and life style.
Optimal gut health is of vital importance to the performance of production animals (fish, poultry, swine, cattle). Gut health is key to making the productivity, well-being and sustainability of animal production more efficient. Directly and indirectly, the environment is a powerful regulator of gastrointestinal physiology that decisively influences the functional state of the animal. Production animals reared under conventional conditions of intensive production are subjected to various exogenous and endogenous sources of environmental factors that can impact gut health. Exogenous factors are environmental stressors derived from external sources connected with diet, infectious disease, mycotoxin exposure, climate (heat and cold), management practices, biosecurity level, housing, litter, feed access, quality, and components. Endogenous factors are host-related such as age, sex, genetics, and breed or are made within the host’s body, such as hormones and neurotransmitters, in response to a stimulus, stressor, or trigger. Endogenous factors serve to communicate signals both locally and distantly in the body. Understanding the interactions between the diverse environmental factors and the different physiological characteristics of the gastrointestinal tract allows us to advance the understanding of gut health and the ability to regulate animal production. The spirit of this book is to critically address how the interactions of different environmental stressors, both internal and external, influence the various functions of the gastrointestinal system of production animals and to be able to use the information to advance scientific research as well as improve the use of the productive tools available.
Comparative Methods and Global Case Studies
Author:
This book introduces law in the context of international business. The basics of law are explored using a clear comparative methodology. International and regional economic institutions are discussed, next to the fundaments of private law. These include contract law, liability law, labour law, company law, privacy law, intellectual property law and international private law. The book goes beyond the usual focus on Western legal systems and uses examples from all over the world to provide students with comprehensive knowledge of business law. It is set up rather broadly, so that it can be used by teachers throughout their entire curriculum. Each chapter ends with a clear summary. With its colourful cases, this book is accessible and fun to read.

Abstract

Chronic intestinal inflammation is associated with strong alterations of the microbial composition of the gut. Probiotic treatments and microbiota-targeting approaches have been considered to reduce the inflammation, improve both gut barrier function as well as overall gastrointestinal health. Here, a murine model of experimental colitis was used to assess the beneficial health effects of Bacillus subtilis SF106 and Bacillus clausii (recently renamed Shouchella clausii) SF174, two spore-forming strains previously characterised in vitro as potential probiotics. Experimental colitis was induced in BALB/c mice by the oral administration of dextran sodium sulphate (DSS) and groups of animals treated with spores of either strain. Spores of both strains reduced the DSS-induced inflammation with spores of B. clausii SF174 more effective than B. subtilis SF106. Spores of both strains remodelled the mouse gut microbiota favouring the presence of beneficial microbes such as members of the Bacteroidetes and Akkermansia genera.

Abstract

The recycling of minerals is crucial for the future circular agriculture. Black soldier fly larvae (BSFL) can accumulate minerals in their body. This study investigated the effects of adding mineral-enriched BSFL, grown on substrates containing sewage sludge recyclates (SSR), to broiler feed to reintroduce minerals from waste streams currently subject to regulatory restrictions back into the nutrient cycle. Feed, nutrient, mineral and heavy metal intake, growth, blood metabolites and immunoglobulins, bone characteristics and mineral status of broilers were studied in response to different mineral-enriched BSFL supplements. Eighty newly-hatched mixed-sex Ross 308 chicks were divided into four groups, with six replicate pens per group. BSFL used in the broiler experiment were grown either on a modified Gainesville fly diet (FD) (L-FD) or on FD supplemented with 4% of sewage sludge biochar (L-BCH), or on the FD supplemented with Single Superphosphate (SSP) SSR (L-SSP). All broilers were fed age-specific diets and either had no access to BSFL (CON) or received 15% of CON birds’ feed intake as defrosted BSFL from three different sources. Inclusion of 15% of mineral-enriched whole BSFL in broiler rations had no adverse effects on growth performance parameters, nutrient intakes, nutrient conversion efficiency, plasma metabolites and immunoglobulins ( P > 0.05 ). Birds in BSFL supply groups had higher serum Ca concentrations than CON birds ( P < 0.05 ). L-BCH supplied birds had a lower serum P than CON birds ( P < 0.05 ). Tibial characteristics and mineral status of birds were not affected by larvae supply ( P > 0.05 ). Heavy metal intake (manganese, iron, zinc, copper, arsenic, cadmium, lead, and mercury) of the birds was not affected by dietary treatments ( P > 0.05 ). In conclusion, 15% of mineral-enriched-BSFL reared on SSP can be included in broiler diets for 42 experimental days without adverse effects on nutrient intakes, growth performance parameters and bone condition.
