From alpha-galactosidases to xylanases, Enzymes in Farm Animal Nutrition provides a comprehensive guide to all aspects associated with enzyme-supplemented animal feeds. It details the history and size of the feed enzyme market, before describing how feed enzymes are manufactured and employed in monogastric, aqua and ruminant diets. This new edition explores considerable advances such as the use of enzymes in fish and shrimp diets, new understanding of how phytases function in the animal, NSPase research and enzymes' extended use in ruminant markets. Covering biochemistry, enzymology and characteristics relevant to animal feed use, this book forms a valuable resource for academics and students of animal nutrition and production, as well as professionals in the animal feed industry.

Enzymes in Human and Animal Nutrition is a detailed reference on enzymes covering detailed information on all relevant aspects fundamental for final use of enzymes in human and animal nutrition. Topics explored include selection, engineering and expression of microbial enzymes, effects of probiotics on enzymes in the digestive tract, potential new sources of enzymes, valorization of plant biomass by food and feed enzymes. Economics and intellectual property issues are also examined. - Examines the role of enzymes in nutrition and in the production of food and animal feed so that food industry and academic researchers can understand applications of enzymes in the health of humans and animals - Begins with a thorough overview of selection, engineering and expression of microbial enzymes - Examines extremophile organisms as a potential new source of enzymes - Includes discussion of analytics, economics and intellectual property to increase applicability of the rest of the book outside of the lab

For more than 30 years, modelling has been an important method for integrating, in a flexible, comprehensive and widely applicable way, basic knowledge and biological concepts on digestion and metabolism in farm animals. The purpose of this book is to present the 'state of art' in this area. The chapters are written by leading teams and researchers in this field of study, mainly from Europe, North America and Australasia. Considerable progress has been made in topics dealing with: modelling methods, feeding behaviour, digestion and metabolic processes in ruminants and monogastric animals. This progress is clearly illustrated by the emergence of a new paradigm in animal nutrition, which has moved from the aim to cover the requirements of the animal to explaining and predicting the responses of the animals to diets (e.g., productivity and efficiency, impact on quality of products, environmental aspects, health and well-being). In this book several chapters illustrate that through empirical models, meta-analysis is an efficient tool to synthesize information gathered over recent decades. In addition, compared with other books on modelling farm animal nutrition, two new aspects received particular attention: expanding knowledge of the individual animal to understanding the functioning and management of herds, and the consideration of the environmental impact of animal production. This book is a valuable source of information for researchers, nutritionists, advisors, and graduate students who want to have up-to-date and concise information on mathematical modelling applied to farm animals.

Weltweit führende Experten geben einen aktuellen Überblick über den gesamten Bereich der Herstellung und Verwendung von Enzymen in der Industrie: - bei der Herstellung von Massengütern wie Glukose oder Fruktose - in der Textil-, Papier-, Nahrungsmittel und Tierfutterindustrie - in der klinischen Diagnose und Therapie - in der Gentechnologie In mehreren ausführlichen Tabellen sind zahlreiche Daten von Enzymen zusammengestellt. Ein umfassendes Literaturverzeichnis ermöglicht einen schellen Zugriff auf Primärliteratur. Gesetzliche Bestimmungen für den sicheren und legalen Gebrauch von Enzymen runden das Buch an. Aus Rezensionen voriger Auflagen: 'Die Qualität...ist so hervorragend, dass es uneingeschränkt als ideale Lektüre jedem Studenten, der eine Einführung in das Gebiet sucht, empfohlen werden kann. ...'Enzymes in Industry' sollte seinen Platz in jeder Bibliothek haben, sei es in der Industrie oder Hochschule, wo es mit Sicherheit oft seinen Nutzen finden wird.' (The Genetic Engineer and Biotechnologist) 'Das Buch ist auf dem neuesten Stand und trotz der Beteiligung von fast 50 Autoren leicht zu lesen. ... Naturwissenschaftler, die sich mit Enzymen beschäftigen, sollten dieses Buch in ihrer Bibliothek haben. Das Buch wird aber auch für den Marketing-Spezialisten, der sich einen Überblick über gegenwärtige und künftige Anwendungen von Enzymen innerhalb und außerhalb der Lebensmittelindustrie machen will, von großem Nutzen sein.'

Animal food production faces many challenges including shortage of high-quality feed ingredients, contribution of greenhouse gases and pollutants to the environment, development of antimicrobial resistance, food safety, and animal health and welfare. This examines these issues over three sections. The first section is the introduction. The second section provides insights into optimization of pasture utilization employing different supplements and feed additives to maximize beef cattle production, use of insect meal as a promising protein feed ingredient, and ruminal microbiome manipulation to improve ruminal fermentation efficiency. The third section discusses accurate estimation of enteric methane emission factors, reduction of enteric methane emissions by means of feeding management and antimethanogenic compounds, and different heavy metal pollution by poultry wastes and associated health hazards.

This book presents specially commissioned reviews of key topics in farm animal metabolism and nutrition, such as repartitioning agents, near infrared reflectance spectroscopy and digestibility and metabolisable energy assays, where major advances have recently been made or which continue to represent issues of significance for students and researchers. Authors include leading researchers from Europe, North America and Australia.

Poultry are the most widely used animal protein source in the world: billions of meat birds are produced globally each year, using 360 million tonnes of feed. Within Europe, over 30,000 companies involved in the production of poultry create an annual turnover of €107 billion. However, maintaining the sustainability of the industry as it moves towards antibiotic-free production is one of the key challenges. Starting with an overview of antibiotics as growth promoters and the challenges faced as the industry moves away from their use, this book then thoroughly considers the potential of pre and probiotic additives in poultry gut health. Based on the renowned World Poultry Science Association UK Branch Poultry Science Symposium 2022, this book provides a thorough and valuable contribution to the field for all involved with the nutrition and production of poultry.

This book addresses a global issue of increasing high quality food from ruminant animals while reducing their impacts on the environment. However, one of the main constraints to livestock development and the underlying cause of the low productivity in many developing countries is inadequate nutrition associated with inefficient utilization of forages and fibrous feed resources. In many countries, fibrous feed makes up the bulk of available feed resource base, which is characterized by scarcity and fluctuating supply in the quantity and quality of feed resources, nutrient imbalance as seen in many native pastures, grasslands and crop residues-based feeding systems with limited use of commercial concentrate feeds such as soybean, cottonseed and groundnut meals, etc. Furthermore, the production of methane, an important greenhouse gas (GHG), from ruminants fed highly fibrous diets such as straws and stover is higher than those animals fed better quality forages or concentrate diets. Recent research shows that supplementing livestock diets with exogenous fibre degrading enzymes can improve feed utilization by enhancing intake, fibre degradation in the rumen and overall digestibility of fibrous feeds which in turn leads to improved animal performance, farmers’ income, and a reduction in GHG emissions. The book editors would like to acknowledge the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture for funding part of the studies that make up some of these chapters and were part of the final reports of a coordinated research project financed by IAEA.

This reference is a "must-read": It explains how an effective and economically viable enzymatic process in industry is developed and presents numerous successful examples which underline the efficiency of biocatalysis.
