Book Description
Increased global meat consumption has led to an increase in livestock production. While the demand for output increases, so has the need for alternative protein sources in feed to minimize the environmental impact of livestock production. Insect protein is a potential alternative to conventional sources of protein (e.g., soybean meal or cottonseed meal) for cattle consuming low-quality forage (LQF). The use of insects as livestock feed has been documented in the literature, and interest is growing; however, the Association of American Feed Control Officials (AAFCO) has only approved the use of dried black soldier fly larvae (BSFL) for salmonid, poultry, swine, and adult dogs. The objective of this experiment was to evaluate the use of Black Soldier Fly Larvae meal (BSFLM) and BSFL frass and larval sheddings (FRS) as novel supplemental proteins for beef steers consuming low-quality forage. Eight ruminally fistulated steers (240.2 ± 22.5 kg of BW) were used in replicated 4 × 4 Latin squares. One of four treatments were provided to each steer per period: a control (CON) with no supplement, cottonseed meal (CSM), partially defatted BSFL meal (BSFLM), or BSFL frass and larval sheddings (FRS). Four 16-day periods were conducted with an 8-d adaptation to treatments, 7-d measurement of intake and digestion, and 1-d collection of ruminal fermentation and microbial samples. Dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) were determined for forage, supplement, ort, and fecal samples. Microbiome analysis of microbial communities' composition was conducted using 16S rRNA sequencing for liquid and solid rumen fractions. Protein supplementation of CSM, BSFLM, and FRS increased forage organic matter (OM) intake (P

Book Description
With a growing human population, food insecurity is becoming a worldwide problem. As the search for sustainable sources of protein continues, black soldier fly larvae come to the forefront as a partial solution. Full of proteins and fats, the larvae will consume most organic matter and rapidly develop into a usable form. Supplementing black soldier fly larvae with oleaginous microbes Arthrobacter AK19 and Rhodococcus rhodochrous increases their body size by 25%, potentially accelerates their development by one day, and increases their conversion efficiency. Supplementing with Bifidobacterium breve decreased body size, slowed development, and decreased conversion efficiency, underscoring the importance of selecting supplemental microbes and testing first on a small-scale. Promising results on the small-scale led to an industrial study, where similar results were also seen, resulting in greater optimization of this system.

Book Description
The future depletion of non-renewable rock phosphorus (P) highlights urgent need for P recycling. Recovered P could be an alternative source of rock P. In order to reintroduce recovered P into nutrient cycle, the present study examined whether this could be achieved by enriching larvae of the black soldier fly (BSFL). We evaluated the effects of supplementing mineral enriched whole BSFL reared on recycled minerals originated from sewage sludge with high P concentration in broiler diets on feed intake (FI), growth performance, alterations in P-relevant metabolites in blood and bone of broilers.eng

Book Description
As food and animal protein demand increases, black soldier fly larvae (BSFL) meal has gained interest in the past couple of years for use in animal feed as an alternative protein ingredient. Black soldier fly larvae is an attractive protein source; however, it is important to evaluate its amino acid (AA) digestibility and metabolic availability (MA) before incorporation in feed formulation. The global objectives of this thesis were to determine the standardized ileal digestibility (SID) coefficient of AA and MA of methionine using the indicator AA oxidation (IAAO) method from BSFL meal, and to compare the results from the two protein quality methodologies. The SID coefficient of indispensable AA in BSFL meal was found to be above 83%, while the MA of methionine was found to be 53.33%. This finding further confirms that SID coefficient tends to overestimate AA bioavailability and that MA is a more accurate representation of bioavailability.

Book Description
Nutrients from livestock & poultry manure are key sources of water pollution. Ever-growing numbers of animals per farm & per acre have increased the risk of water pollution. New Clean Water Act regulations compel the large confined animal producers to meet nutrient application standards when applying manure to the land, & USDA encourages all animal feeding operations to do the same. The additional costs for managing manure (such as hauling manure off the farm) have implications for feedgrain producers & consumers as well. This report¿s farm level analysis examines onfarm technical choice & producer costs across major U.S. production areas for hauling manure to the minimum amount of land needed to assimilate manure nutrients.

Book Description
Interestingly, some relief from today's woes may come from ancient human practices. While current agri-food production models rely on abundant supplies of water, energy, and arable land and generate significant greenhouse gas emissions in addition to forest and biodiversity loss, past practices point toward more affordable and sustainable paths. Different forms of insect farming and soilless crop farming, or hydroponics, have existed for centuries. In this report the authors make a persuasive case that frontier agriculture, particularly insect and hydroponic farming, can complement conventional agriculture. Both technologies reuse society's agricultural and organic industrial waste to produce nutritious food and animal feed without continuing to deplete the planet's land and water resources, thereby converting the world's wasteful linear food economy into a sustainable, circular food economy. As the report shows, insect and hydroponic farming can create jobs, diversify livelihoods, improve nutrition, and provide many other benefits in African and fragile, conflict-affected countries. Together with other investments in climate-smart agriculture, such as trees on farms, alternate wetting and drying rice systems, conservation agriculture, and sustainable livestock, these technologies are part of a promising menu of solutions that can help countries move their land, food, water, and agriculture systems toward greater sustainability and reduced emissions. This is a key consideration as the World Bank renews its commitment to support countries' climate action plans. This book is the Bank's first attempt to look at insect and hydroponic farming as possible solutions to the world's climate and food and nutrition security crisis and may represent a new chapter in the Bank's evolving efforts to help feed and sustain the planet.

Book Description
Choice Reviews, Outstanding Academic Title Techniques and systems for processing food scraps, manure, yard debris, paper, and more Turning waste into wealth sounds too good to be true, but many worm farmers are finding that vermicomposting is a reliable way to do just that. Vermicast—a biologically active, nutrient-rich mix of earthworm castings and decomposed organic matter—sells for $400 or more per cubic yard. Compare that to regular compost, sold at about $30 a cubic yard, and you’ll see why vermicomposting has taken root in most countries and on every continent but Antarctica. Vermicomposting is also one of the best sustainable solutions for organic waste management. Vermicomposting manure and crop wastes on farms improves crop yields while reducing demand for off-farm inputs. Vermicast has higher nutrient levels and lower soluble salt content than regular compost, and it improves soil aeration, porosity, and water retention. Plus, vermicast suppresses plant diseases and insect attacks. Municipalities, businesses, community gardens, schools, and universities can set up vermicomposting operations to process food residuals and other waste materials. The Worm Farmer’s Handbook details the ins and outs of vermicomposting for mid- to large-scale operations, including how to recycle organic materials ranging from food wastes and yard trimmings to manure and shredded office paper. Vermicomposting expert Rhonda Sherman shares what she has learned over twenty-five years working with commercial worm growers and researchers around the world. Her profiles of successful worm growers across the United States and from New Zealand to the Middle East and Europe describe their proven methods and systems. This book digs into all the details, including: Choosing the right production system Regulatory issues and developing a business and marketing plan Finding and managing feedstocks Pre-composting: why and how to do it Monitoring an active worm bed Harvesting, screening, testing, packaging, and storing vermicast Markets for earthworms and vermicast Food security: how vermicast benefits soils and plants Keys to success: avoiding common pitfalls From livestock farms and restaurants to colleges, military bases, and prisons, Sherman details why and how commercial-scale vermicomposting is a fast-growing, sustainable solution for organic waste management. The Worm Farmer’s Handbook is the first and only authoritative how-to guide that goes beyond small-scale operations and demystifies the science and logistics of the fascinating process that is vermicomposting.

Book Description
This book focuses on the search for possibilities of valuable food waste transformation directly to food, by introducing the 'Waste-to-Food Concept' . It goes beyond conventional technologies of food waste transformation into compost and organic fertilisers (downgrading the value of food waste biomass). It focuses on novel processing technologies and bio-transformation methods to food grade biomass. Food waste biomass of non-food grade quality can be used for high-value components extraction and as a carbon and nitrogen source for specific algae and insect cultivation. The discussed methods are complex and contradictive with multiple legal, socio-economic, environmental and nutritional issues. Therefore, this book thoroughly focuses on analysing these issues, and searching for viable ways to proceed, such as eco-design and application of Artificial Intelligence algorithms as solutions for the complex Waste-to-Food system.

Book Description
Insects will be appearing on our store shelves, menus, and plates within the decade. In The Insect Cookbook, two entomologists and a chef make the case for insects as a sustainable source of protein for humans and a necessary part of our future diet. They provide consumers and chefs with the essential facts about insects for culinary use, with recipes simple enough to make at home yet boasting the international flair of the world’s most chic dishes. Insects are delicious and healthy. A large proportion of the world’s population eats them as a delicacy. In Mexico, roasted ants are considered a treat, and the Japanese adore wasps. Insects not only are a tasty and versatile ingredient in the kitchen, but also are full of protein. Furthermore, insect farming is much more sustainable than meat production. The Insect Cookbook contains delicious recipes; interviews with top chefs, insect farmers, political figures, and nutrition experts (including chef René Redzepi, whose establishment was elected three times as “best restaurant of the world”; Kofi Annan, former secretary-general of the United Nations; and Daniella Martin of Girl Meets Bug); and all you want to know about cooking with insects, teaching twenty-first-century consumers where to buy insects, which ones are edible, and how to store and prepare them at home and in commercial spaces.
