Quantifying Diets of Wildlife and Fish presents different techniques available to study animal diets. Ecologists determine animal diets to build natural history knowledge, test hypotheses in ecological theory and make informed management decisions for important ecosystems. Many researchers use techniques traditionally applied to the animals they study, rather than techniques with the greatest potential for the aims of each project. In an effort to encourage researchers to consider new approaches, this book focuses on the techniques, rather than on particular groups of organisms or specific environments. With contributions from leading ecologists, chapters explore experimental design, observational techniques (including new technologies), stomach contents and faecal analysis, eDNA, tracers and stable isotopes. They also cover the latest multivariate methods of analyses suitable for describing animal diets and feeding relationships, as well as testing hypotheses relevant to ecological theory, environmental management and biological conservation. The expert knowledge provided will encourage readers to look beyond the boundaries of their specialties, assist in testing important hypotheses and provide insights into management problems. The examples in this book cover a range of vertebrates and invertebrates, as well as different environments, to open these methods up for novice ecologists and stimulate lateral thinking in more experienced researchers.

NAMED A TOP-TEN BEST BOOK OF 2023 BY SCIENTIFIC AMERICAN A “fascinating” exploration (Elizabeth Kolbert) of how ecosystems are sculpted and sustained by animals eating, pooping, and dying—and how these fundamental functions could help save us from climate catastrophe. If forests are the lungs of the planet, then animals migrating across oceans, streams, and mountains—eating, pooping, and dying along the way—are its heart and arteries, pumping nitrogen and phosphorus from deep-sea gorges up to mountain peaks, from the Arctic to the Caribbean. Without this conveyor belt of crucial, life-sustaining nutrients, the world would look very different. The dynamics that shape our physical world—atmospheric chemistry, geothermal forces, plate tectonics, and erosion through wind and rain—have been explored for decades. But the effects on local ecosystems of less glamorous forces—rotting carcasses and deposited feces—as well as their impact on the global climate cycle, have been largely overlooked. The simple truth is that pooping and peeing are daily rituals for almost all animals, the ellipses of ecology that flow through life. We eat, we poop, and we die. From the volcanoes of Iceland to the tropical waters of Hawaii, the great plains of the American heartland, and beyond, Eat, Poop, Die, “compulsively readable” (Shelby Van Pelt), takes readers on an exhilarating and enlightening global adventure, revealing the remarkable ways in which the most basic biological activities of animals make and remake the world—and how a deeper understanding of these cycles provides us with opportunities to undo the environmental damage humanity has wrought on the planet we call home.

Cet ouvrage en impression à la demande sera envoyé sous 3 semaines environ (France métropolitaine) et dans un colis séparé en cas de commande avec un autre livre papier.Depuis une dizaine d'années, de nombreuses études questionnent notre consommation d'aliments d'origine animale. Les impacts de l'élevage sur l'environnement, les effets sur la santé humaine d'une consommation excessive de viande rouge et de charcuterie ainsi que les préoccupations d'éthique envers les animaux ont fait évoluer l'image de ces produits. Peu de travaux ont cependant analysé leur qualité dans ses différentes dimensions. C'est ce que propose cet ouvrage qui reprend les principaux enseignements d'une expertise scientifique collective coordonnée par INRAE en 2020. Il caractérise conjointement les propriétés organoleptiques, nutritionnelles, sanitaires, technologiques, commerciales, d'usage et d'image de ces aliments.Embrassant toute la chaîne de fabrication de l'aliment, il pointe les facteurs d'élevage et de transformation influant sur la qualité et souligne les possibles antagonismes ou synergies entre les dimensions de la qualité et entre les différentes étapes de l'élaboration du produit. Les auteurs comparent, par ailleurs, les engagements spécifiques des produits bénéficiant de signes de qualité (bio, Label rouge, AOP, IGP, STG).

This book is a bridge between ecological paradigms – organismal/community approaches to food web dynamics and ecosystem-level approaches to production. The unification of organismal, community, and ecosystem approaches in ecology is emerging due to the growing availability of new techniques for assessing trophic interactions and their implications for ecosystems. Trophic Ecology is a formal text for both newcomers to the discipline as well as seasoned professionals looking for new ideas and refreshers on old topics. A wide range of topics are explained including autotrophy, heterotrophy, omnivory, decomposition, foraging behavior and theory, trophic cascades, bioenergetics, and production. The audience is upper-level undergraduate students and entry-level graduate students interested in autecological, organismal approaches to ecology, community and ecosystem ecology. It is also a reference text for instructors teaching upper-division courses, providing examples from the literature, quantitative approaches to teach, and new hypotheses yet to be fully tested by ecologists.

Development in agricultural sciences, particularly in farm animal sciences, resulted in the increased productivity to meet the demand for high quality and relatively cheap protein sources for human nutrition. In parallel, this increased productivity challenges the adequate supply of nutrients, including protein and energy, needed to cover not only high performances, but also insure animal health and welfare, reproduction and quality of products in a sustainable environment. The precise understanding of the animal biology is crucial for animal health and welfare, sustainable animal production, and health of animal product consumers. This book focuses on combining basic and applied research and its practical applications. To achieve these goals, many important topics are presented and discussed in detail. The most important issues in this book are: physiological aspects of protein and energy metabolism and nutrition; animal health and welfare metabolic related issues; effect of feeds and feed processing on energy and protein digestion and metabolism; methodological aspects of research on protein and energy metabolism; environment protection and enhancement of the quality and health-promoting features of animal products. This book constitutes a good source of knowledge for those who like to be up to date with the newest trends and findings in energy and protein metabolism in farm animals.

This book provides developmental data regarding piglets (with a focus on the gastrointestinal tract), data related to amino acid metabolism in pigs, data related to nutritional and physiological functions of amino acids in pigs, nutritional requirements for amino acids in pigs, signaling roles of amino acids, methodological aspects in amino acid research and the pig model for studying amino acid-related human diseases.

Quality of feed nutrition is influenced not only by the content but also by some other aspects such as, feed presentation, hygiene, anti-nutritional factors, digestibility and palatability. Feed additives provide a mechanism by which such dietary deficiencies can be addressed and also benefits not only associated with the nutrition and thus the growth rate of the animal concerned, but also its health and welfare. Feed additives could modify animal metabolism in specific and direct ways by improving production efficiency (weight gain or milk yield); improving carcass composition in growing animals; increasing milk yield in lactating animals; and decreasing animal waste per production unit. This book discusses the impacts of feed additives on animal metabolism, health and production.

This is a book about proximate mechanisms. Although some theoreti­ cal structure is used to introduce the subject, the intent is to offer a comprehensive view of the mechanistic side of searching (or foraging) so as to balance the current emphasis of books on mathematical and functional models. It seems to me that the pendulum needs to swing back to studies of how animals behave, and that maybe in so doing models will become valuable again in driving experimentation. I have probably included too many examples in this book, and some are even presented in great detail. Hopefully, they provide a complete picture of the kind of animals used, the experimental setup, the kinds of data yielded, and how the data were analysed. I have done this in response to frustrating experiences of reading chapters in behavioural ecobgy books that provide insufficient information with which to evaluate an author's conclusion.

'Feed efficiency in swine'has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.

Animal nutrition is a fast changing field of expertise. Newly developed scientific knowledge is quickly adapted to better understand the integral balance between different organs and the digestive system. Society demands that the feed industry responds to consumer issues such as food safety, sustainability of animal production, animal health and welfare, carbon foot printing etc. via altering feeding programs. The practising nutritionist needs to implement this vast knowledge into practical feed formulations in a cost effective way in order to produce feeds and animal products efficiently. This book addresses current topics of interest to researchers and nutritionists in animal research, the feed and allied industry. This includes: immunomodulation, gut barrier functions in gut health, oxidative stress in weaned piglets, glutamine as an functional amino acid, energy evaluation of feedstuffs for layers, reduction of the risk of Salmonella infections, glucogenic nutrients as a predictor of milk production, reduction of methanogenesis in ruminants, glucose metabolism and insulin resistance in sows and much more. This reference book will be of vital interest to all involved in animal nutrition and the animal production industry.

Energy and Protein Metabolism and Nutrition is of increasing importance as greater efficiency and health benefits are sought in feed for animal production. Top scientists from around the world have collaborated in this book to exchange expertise and knowledge on the latest developments in the field. The topics range from tissue metabolism and regulation mechanisms to practical aspects of energy and protein nutrition and feeding. A better and deeper understanding of nutrient metabolism and nutrition can only be achieved by integrating the outcomes of scientists researching different aspects of this topic. In doing this practical outcomes are sought for the direct benefit of producers and consumers. Special topics such as the links between energy/protein metabolism and nutrition regarding food quality, nutrigenomics, environmental sustainability and animal welfare in relation to the topic are all explored. This book is a valuable resource to all researchers and industry professionals who concern themselves with animal nutrition.

'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.'

All animals have to eat, but feeding behavior goes far beyond predators and prey. Animals have a variety of ways to find food.

Dairy goats have long been considered an important source of income for rural populations, providing the opportunity for profitable and sustainable diversity for small farms. Their importance is also increasing in intensive feeding systems and in large farms. They are highly adaptable due to their unique feeding habits and have become popular livestock animals in a range of environments, from temperate grasslands to subtropical, semi-arid and mountainous areas. Moreover, goat milk products are finding a growing acceptance in the world market and research has increased in feeding strategies for improved productivity and quality. Examining all aspects of dairy goat feeding and nutrition, this book represents a long awaited review of recent scientific research and updated techniques. Chapters discuss aspects such as the modelling and production of goat's milk as well as the estimation of nutrient requirements and food intake of goats.

Inositol phosphates are a group of organic compounds found widely in the natural environment. They are important in agriculture because they constitute most of the phosphorus in grain seeds, but they cannot be digested by some animals. As a result, considerable research has been directed towards improving the digestibility of inositol phosphates in animal diets. Inositol phosphates are also abundant in soils and water bodies, yet a clear understanding of their behaviour in the environment remains elusive. This is surprising given the importance of phosphorus in the nutrition of both terrestrial and aquatic ecosystems. Written by leading experts, this book brings together critical reviews on inositol phosphates in agriculture, ecology, and the environment. The sixteen chapters cover a diverse range of topics, including the synthesis and hydrolysis of inositol phosphates, their role in animal nutrition, and their fate in soils and aquatic ecosystems. It will prove valuable to a wide readership in the agricultural and biological sciences, and will serve as a unique reference source on this emerging topic.

Proper formulation of diets for horses depends on adequate knowledge of their nutrient requirements. These requirements depend on the breed and age of the horse and whether it is exercising, pregnant, or lactating. A great deal of new information has been accumulated since the publication 17 years ago of the last edition of Nutrient Requirements of Horses. This new edition features a detailed review of scientific literature, summarizing all the latest information, and provides a new set of requirements based on revised data. Also included is updated information on the composition of feeds, feed additives, and other compounds routinely fed to horses. The effects of physiological factors, such as exercise, and environmental factors, such as temperature and humidity, are covered, as well. Nutrient Requirements of Horses also contains information on several nutritional and metabolic diseases that horses often have. Designed primarily as a reference, both practical and technical, Nutrient Requirements of Horses is intended to ensure that the diets of horses and other equids contain adequate amounts of nutrients and that the intakes of certain nutrients are not so excessive that they inhibit performance or impair health. This book is primarily intended for animal nutritionists, veterinarians, and other scientists; however, individual horse owners and managers will also find some of this material useful. Professors who teach graduate courses in animal nutrition will find Nutrient Requirements of Horses beneficial as a textbook.

Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. For instance, pythons rarely eat, but when they do, their meals are large—as much as 60 percent larger than their own bodies. The snake's digestive system is normally dormant, but during digestion metabolic rates can increase fortyfold. A python digesting quietly on the forest floor has the metabolic rate of thoroughbred in a dead heat. This and related foraging processes have broad applications in ecology, cognitive science, anthropology, and conservation biology—and they can be further extrapolated in economics, neurobiology, and computer science. Foraging is the first comprehensive review of the topic in more than twenty years. A monumental undertaking, this volume brings together twenty-two experts from throughout the field to offer the latest on the mechanics of foraging, modern foraging theory, and foraging ecology. The fourteen essays cover all the relevant issues, including cognition, individual behavior, caching behavior, parental behavior, antipredator behavior, social behavior, population and community ecology, herbivory, and conservation. Considering a wide range of taxa, from birds to mammals to amphibians, Foraging will be the definitive guide to the field.

Derived from the 28th Poultry Science Symposium of the World's Poultry Science Association (UK), this book focuses on the current interest of the phasing out of antibiotic use in poultry and covers in-depth interactions between the bird, its diet and potential pathogens. It also demonstrates the understanding of the gut health in the 21st century of commercial poultry and flocks and the ultimate safety of poultry product in the human food chain.

Domestication of vertebrates is based on the understanding of the needs of animals in their natural environment. Thus the success of this domestication throughout human history is largely dependant of the knowledge of the animal feeding behaviour. The aim of this volume is to provide advanced students and researchers with a review of current knowledge of feeding in domestic mammals and birds. The book also presents chapters on feeding behaviour in particular species; the scope is wide, covering not only ruminants, poultry and pigs, but also more specifically horses, rabbits and ostrich. Contributors include leading research workers from Europe, USA, Australia and South Africa.
