The aim of this Special Issue is to publish high quality papers concerning poultry nutrition and the interrelations between nutrition, metabolism, microbiota and the health of poultry. Therefore, I invite submissions of recent findings, as original research or reviews, on poultry nutrition, including, but not limited to, the following areas: the effect of feeding on poultry meat end egg quality; nutrient requirements of poultry; the use of functional feed additives to improve gut health and immune status; microbiota; nutraceuticals; soybean meal replacers as alternative sources of protein for poultry; the effects of feeding poultry on environmental impacts; the use of feed/food by-products in poultry diet; and feed technology.

Due to the wide acceptance of poultry meat and eggs, poultry farming is the fastest growing global livestock industry. Nutrition plays a vital role in economic production and the maintenance of proper poultry health. Therefore, there is a great need to update balanced nutrient requirements for new breeds, utilize alternative feed resources, evaluate newer feed additives to optimize production while excluding antimicrobial feed additives and maintain overall health. The first section of this book contains six chapters that discuss the utilization of unconventional feeds, nanominerals to reduce mineral proportions in diets, and water intake affected by environmental temperature. The second section contains six chapters that describe proper nutritional management to improve gut health and immunity, the prevention of common diseases, and the amelioration of heat stress in poultry.

This book covers hot topics in the nutrition and metabolism of terrestrial and aquatic animals, including the interorgan transport and utilization of water, minerals, amino acids, glucose, and fructose; the development of alternatives to in-feed antibiotics for animals (e.g., swine and poultry); and metabolic disorders (or diseases) resulting from nutrient deficiencies. It enables readers to understand the crucial roles of nutrients in the nutrition, growth, development, and health of animals. Such knowledge has important implications for humans. Readers will also learn from well-written chapters about the use of new genome-editing biotechnologies to generate animals (e.g., cows and swine) as bioreactors that can produce large amounts of pharmaceutical proteins and other molecules to improve the health and well-being of humans and other animals, as well as the growth and productivity of farm animals. Furthermore, the book provides useful information on the use of animals (e.g., cattle, swine, sheep, chickens, and fish) as models in biomedical research to prevent and treat human diseases, develop infant formulas, and improve the cardiovascular and metabolic health of offspring with prenatal growth restriction. Editor of this book is an internationally recognized expert in nutrition and metabolisms. He has about 40 years of experience with research and teaching at world-class universities in the subject matters. He has published more than 660 papers in peer-reviewed journals, 90 chapters in books, and authored two text/reference books, with a very high H-index of 127 and more than 66,000 citations in Google Scholar. This publication is a useful reference for nutrition and biomedical professionals, as well as undergraduate and graduate students in animal science, aquaculture, zoology, wildlife, veterinary medicine, biology, biochemistry, food science, nutrition, pharmacology, physiology, toxicology, and other related disciplines. In addition, all chapters provide general and specific references to nutrition and metabolism for researchers and practitioners in animal agriculture (including aquaculture), dietitians, animal and human medicines, and for government policy makers.

The book has detailed information about the recent advances made and future course expected in the field of poultry nutrition. In the past, main focus was on increasing the meat and egg production to meet the ever-increasing demand of animal protein globally. However, futuristic demand in poultry is driven not only by the need to maximize biological and economic performance of birds, but also by societal issues (environmental, welfare, antibiotic growth promoters, traceability and use of genetically modified ingredients). Thus, an attempt has been made to assemble most of the recent scientific research work made, in order to enlighten and update the knowledge of students, teachers, research scholars, and industrialists in the field of poultry nutrition.

Advances in Poultry Welfare provides a targeted overview of contemporary developments in poultry welfare. The reviews in the volume address topical issues related to poultry welfare research and assessment, with a focus on identifying practical strategies for improvement as well as information gaps that remain to be filled. Part One provides an introduction to poultry production systems and gives a broad overview of current poultry welfare issues. Part Two moves on to review several aspects of poultry management, focusing on hatchery practices, early rearing, and slaughter. Part Three deals with welfare assessment on the farm, while Part Four explores continuing challenges, such as feather pecking and skeletal problems. This is followed in Part Five by a discussion of emerging issues, with chapters covering alternative parasite control methods, backyard poultry production, mass depopulation, and genetic approaches to reducing the impact of environmental stressors on welfare. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs, and poultry. With its expert editor and international team of contributors, Advances in Poultry Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of poultry. - Provides in-depth reviews of emerging topics, research and applications in poultry welfare - Integral part of a wider series, Advances in Agricultural Animal Welfare, which will provide comprehensive coverage of animal welfare of the world's major farmed animals - Covers a range of topical issues within the field, from beak-trimming and skeletal problems, to early rearing and the design and management of poultry production systems - Edited by a distinguished leader in the field

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.
