Enzymes in Poultry and Swine Nutrition: Proceedings of the First Chinese Symposium on Feed Enzymes, Nanjing, PRC

"This fully updated new edition provides a comprehensive guide to enzyme-supplemented animal feeds. It explores using enzymes in fish and shrimp diets, new understanding of how phytases function, and NSPase research. It also includes new chapters on enzyme combinations, antibiotic free diets and measuring response in feed trials"--

Covering a variety of essential topics relating to commercial poultry nutrition and production—including feeding systems and poultry diets—this complete reference is ideal for professionals in the poultry-feed industries, veterinarians, nutritionists, and farm managers. Detailed and accessible, the guide analyzes commercial poultry production at a worldwide level and outlines the importance it holds for maintaining essential food supplies. With ingredient evaluations and diet formulations, the study's compressive models for feeding programs target a wide range of commercially prominent poultry, including laying hens, broiler chickens, turkeys, ducks, geese, and game birds, among others.

Amino acids (AAs) are not only building blocks of protein, but are also signalling molecules as well as regulators of gene expression and the protein phosphorylation cascade. Additionally, AAs are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with each having enormous biological importance. For example, physiological concentrations of AA metabolites (e.g., nitric oxide, polyamines, glutathione, taurine, thyroid hormones, and serotonin) are required for cell functions. Growing evidence shows that humans and animals have dietary requirements for all proteinogenic AAs. Mammals, birds and fish also have species- and age-dependent needs for some AA-related substances. However, elevated levels of other products (e.g., ammonia, homocysteine, H2S, and asymmetric dimethylarginine) are pathogenic factors for neurological disorders, oxidative stress, and cardiovascular disease. Thus, optimal amounts of AAs and their ratios in diets and circulation are crucial for whole body homeostasis and health. Adequate provision of one or a mixture of functional AAs or metabolites may be beneficial for ameliorating health problems at various stages of the life cycle (e.g., fetal growth restriction, neonatal morbidity and mortality, weaning-associated intestinal dysfunction and wasting syndrome, obesity, diabetes, cardiovascular disease, the metabolic syndrome, and infertility). Dietary supplementation of these nutrients can also optimize the efficiency of metabolic transformations to enhance muscle growth, milk production, and athletic performance, while preventing excess fat deposition and reducing adiposity. Therefore, functional AAs hold great promise in improving the growth, health and well-being of individuals.

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.

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

Safety and Practice for Organic Food covers current food safety issues and trends. It provides detailed information on all organic and pasture practices including produce-only, farm-animal-only or integrated crop-livestock farming, as well as the impact of these practices on food safety and foodborne infections. The book explores food products that organic, integrated and traditional farming systems are contributing to consumers. As the demand for organic food products grows faster than ever, this book discusses current and improved practices for safer products. Moreover, the book explores progressive directions, such as the application of next-generation sequencing and genomics to aid in the understanding of the microbial ecology of the agro-environment and how farmer education can contribute to sustainable and safe food. Safety and Practice for Organic Food is a unique source of organic agricultural practices and food production for researchers, academics and professionals at agriculture-based universities and colleges who are involved in food science, animal sciences including poultry science, food safety, food microbiology, plant science and agricultural extension. This book is also an excellent source of information for regulators and federal government officials (USDA, FDA, EPA) and the food processing industry. - Discusses limitations in pre-harvest and post-harvest level practices with specific information on risk and bio-security of existing organic production systems - Explores policies and guidelines for organic food production and future directions for safer and more sustainable management - Presents microbial and other biological hazards at pre-harvest and post-harvest levels

Disturbances in the gastrointestinal (GI) tract caused by internal and external influences can cause large economic losses in both the pig and poultry industries. Traditionally, diseases and conditions of the GI tract that can cause losses have been controlled by antimicrobial compounds administered in the feed and (or) water, such as antibiotics, coccidiostats, zootechnical feed additives and trace elements such as zinc and copper. However, legislation and rulings in various parts of the world coupled with a growing sentiment to reduce the use of these compounds in the intensive livestock industries have caused a reassessment of measures to influence GI tract structure and function ('gut health'), and have caused unparalleled interest in alternative strategies (genetic, dietary, management, environmental) to effectively manage the GI tract under conditions of external and internal challenge. Despite the wide array of products and strategies available to the pig and poultry industries that influence 'gut health', a term in itself that is often misunderstood and misinterpreted, it is important that the industries continue to investigate and understand the underpinning sciences that influence GI tract structure and function, especially at critical life stages. Ultimately, the cost-benefit of adopting such practices to influence 'gut health' requires consideration.
