Poultry are farmed and are important sources of protein throughout the world. All students of agriculture are likely to be required to study poultry science to at least an introductory level. However, hitherto there has been no suitable textbook serving the needs of students taking a general introductory course in poultry science. This book aims to fill this gap. It explains the science underlying the productive processes of growth, reproduction and incubation. The applications of nutrition and breeding techniques are described. The book covers all the commercially important poultry species, including turkeys, quail, guinea fowls, ducks and geese, but the main emphasis is on the domestic fowl. The overall purpose is to provide the student with an understanding of the characteristics and physiological responses of domesticated poultry, with particular reference to production. The emphasis is on modelling responses rather than on biochemical and hormonal processes. The author stresses basic concepts and models, rather than practical production systems, so that the book should have worldwide applicability. The book represents a key text for degree and advanced diploma courses in agriculture.

Organic cattle farming is on the increase, with consumer demand for organic milk and meat growing yearly. Beginning with an overview of the aims and principles behind organic cattle production, this book presents extensive information about how to feed cattle so that the milk and meat produced meet organic standards, and provides a comprehensive summary of ruminant digestive processes and nutrition. Since the publication of the first edition, global consumers have increasingly become concerned with the sustainability of meat production. Here, Robert Blair considers the interrelationships of sustainable practices and profitability of organic herds, reviewing how to improve forage production and quality, and minimizing the need for supplementary feeding using off-farm ingredients. This new edition also covers: - Managing a recurrent shortage of organic feed ingredients, due to increased GM feed crop cultivation worldwide - Current findings on appropriate breeds and grazing systems for forage-based organic production - Diet-related health issues in organic herds and the effects of organic production on meat and milk quality. Required reading for animal science researchers, advisory personnel that service the organic milk and beef industries and students interested in organic milk and meat production, this book is also a useful resource for organic farming associations, veterinarians, and feed and food industry personnel.

Transgenic plants are cultivated on a large scale worldwide, and most of the harvested products are fed to domestic animals. By gathering together more than 150 feeding studies with food-producing animals, and covering both first- and second-generation transgenic plants, this book provides the first central resource of this information for researchers, students, policy makers and all those who are interested in future developments in the field.

This book is an officially authorised advisory manual that implements the recommendations on the energy and protein requirements of cattle, sheep and goats made by the AFRC Technical Committee on Responses to Nutrients (TCORN) since its establishment in 1982. TCORN has produced a series of numbered reports including No. 5 in 1990 on 'Nutrient Requirements on Ruminant Animals: Energy' and in 1992, No. 9 'Nutrient Requirements of Ruminant Animals: Protein'. The former recommended, with only minor modifications, the adoption of the AFRC's 1980 Technical Review's full recommendations on energy requirements of ruminants, while the latter recommended the adoption of a protein system based on Metabolisable Protein as the unit. Opportunity has been taken to include material from TCORN Report No. 8, 1991 on the 'Voluntary Intake of Silage by Cattle' and from an unpublished TCORN Report on the 'Nutrition of Goats'. The current volume presents these recommendations in a practical form designed for use by advisors, farmers, lecturers, research workers and students concerned with the nutrition of ruminant animals. The manual includes 45 tables of requirements (incorporating agreed safety margins) and 29 example diets.

Their natural beauty, exceptional variety and unique biology make birds (Aves) one of the most fascinating groups of animals. They are also of great importance to humans as food and as experimental subjects that have catalyzed significant advances in many areas of biological research. Central to our ability to maintain and develop these resources is a thorough understanding of avian nutrition. This book presents, uniquely, all aspects of our current knowledge, drawn from such diverse disciplines as physiological ecology, poultry production, zoo biology and biomedical science. The physical and biochemical processes of digestion, the metabolic functions of nutrients and the diversity of evolutionary adaptations required to accommodate very different foodstuffs are examined in depth. Emphasis is placed on the quantitative nature of nutrition and the practical consequences for the dietary requirements of captive and wild avian populations throughout their life cycle. This book is key reading for advanced students of animal nutrition and poultry science and for research ornithologists. It will also be valuable for practicing nutritionists working with farmed, pet, zoo or wild birds and represents an essential purchase for libraries of animal science, veterinary medicine and ornithology.

"Vitamins in Animal and Human Nutrition "contains concise, up-to-date information on vitamin nutrition for both animals and humans. The author defines these nutrients and describes their fascinating discovery, history and relationship to various diseases and deficiencies. Discussion of vitamins also includes their chemical structure, properties and antagonists; analytical procedures; metabolism; functions; requirements; sources; supplementation and toxicity. Vitamin-like substances, essential fatty acids and vitamin supplementation considerations are also examined.

This book will be useful worldwide as a textbook and as an authoritative reference for research and extension specialists, feed manufacturers, teachers, students and others. It provides a well-balanced approach to both animal and clinical human nutrition and compares chemical, metabolic and functional aspects of vitamins and their practical and applied considerations. A unique feature of the book is its description of the implications of vitamin deficiencies and excesses and the conditions that might occur in human and various animal species.

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 behavior. 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 behavior 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.

Mineral nutrition of livestock is an area of significant importance due to its contribution to farm animal economics and health. With a focus on macromineral utilization in farm animals, this book brings together quantitative aspects of phosphorus and calcium metabolism in farm animals in chapters written by leading researchers worldwide. It covers isotope dilution technique, phosphorus and calcium utilization in ruminants (sheep, goats and cattle) and non-ruminants (swine, horses) and recommended value of phosphorus and calcium inclusion in feed. It is an essential resource for researchers and students in animal sciences and nutrition.

The immunologist and bestselling author Attilio Speciani dispels the cliches about so-called 'food intolerances' and guides the reader to a healthy and better relationship with food. Colitis, migraines, hormonal changes, arthritis, autoimmune diseases, imbalances of metabolism and many other disorders, from the most common to the most severe, are often related to diet. There is a close relationship between food and health, and when the natural and physiological relationship with food changes, due to food excesses or the repeated introduction of food, the organism generates measurable inflammatory signals that induce and maintain many conditions or diseases

Growing numbers of pet owners are giving their pets dietary supplements in hopes of supporting their health. Many people presume that supplements are safer than drugs, but the reality is that there are very limited safety data on dietary supplements for pets. Many challenges stand in the way of determining whether animal dietary supplements are safe and at what dosage. Supplements considered safe in humans and other species are not always safe in horses, dogs, and cats. An improved adverse event reporting system is badly needed. Also, the absence of laws and regulations that specifically address animal dietary supplements causes considerable confusion to the industry and to the public. Clear and precise regulations are needed to allow only safe dietary supplements on the market. This book examines issues in determining safety of animal dietary supplements in general, and the safety of three animal dietary supplements; lutein, evening primrose oil, and garlic, in particular.

Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in both animals and humans through its incorporation into selenoproteins as the amino acid selenocysteine. Among many minerals Se has a special place being the most controversial trace element with a narrow gap between essentiality and toxicity. Indeed there are important environmental issues considering selenium as a pollutant from the one hand and global selenium deficiency on the other. In fact, Se deficiency is considered as a risk factor for the development of various diseases in human and animals. Decreased Se availability from soils as a result of low soil pH and usage of synthetic fertilizers is the major concern in European countries causing inadequate Se levels in food and feeds.Furthermore, it seems likely that sodium selenite used for the last 30 years as a feed supplement is not an optimal form of Se and the usage of organic selenium in animal diets could help to maintain optimal Se status as well as high immunocompetence, productive and reproductive performance. The aim of the present volume is to provide updated information on several important Se-related subjects, including Se status in Europe and ways of its improvement, advances in Se analysis and speciation in biological material, roles of selenium in poultry, pig and ruminant nutrition. In this title, production of functional Se-enriched food, the relationship between selenium and mycotoxins, polyunsaturated fatty acids as well as reoviruses are also addressed. This collection of articles will provide nutritionists, veterinarians, human doctors, researchers and any other readers with new insights into the exciting world of the goddess of the moon - Selenium.

Animal breeding has been complicated by persisting factors across species, cultures, geography, and time. In Made to Order, Margaret E. Derry explains these factors and other breeding concerns in relation to both animals and society in North America and Europe over the past three centuries. Made to Order addresses how breeding methodology evolved, what characterized the aims of breeding, and the way structures were put in place to regulate the occupation. Illustrated by case studies on important farm animals and companion species, the book presents a synthetic overview of livestock breeding as a whole. It gives considerable emphasis to genetics and animal breeding in the post-1960 period, the relationship between environmental and improvement breeding, and regulation of breeding as seen through pedigrees. In doing so, Made to Order shows how studying the ancient human practice of animal breeding can illuminate the ways in which human thinking, theorizing, and evolving characterize our interactions with all-natural processes.

Since its inception in 1945, this serial has provided critical and integrating articles written by research specialists who integrate industrial, analytical, and technological aspects of biochemistry, organic chemistry, and instrumentation methodology in the study of carbohydrates. The articles provide a definitive interpretation of the current status and future trends in carbohydrate chemistry and biochemistry.

Post-pelleting addition of heat sensitive additives is a way to avoid damage to additives. It also contributes to the reduction of carry-over and cross contamination. The use of liquid additives in a post-pelleting application (PPA) may be an alternative technological solution whereby an even dosing of an additive into animal feed can be provided together with a virtually 100 per cent recovery of the additive. This will ultimately benefit the food manufacturer since it will provide more flexibility in terms of the demand for special custom-build feeds. The implementation of liquid additive systems gives rise to a number of requirements for both feed and equipment. This booklet presents a compilation of the literature associated with the use of liquid additives. It can be used as a ready reference by process engineers, nutritionists, researchers and students.

The fifth edition of this important book reviews recent advances in livestock mineral nutrition, updated throughout with new references that reflect the growing complexity of mineral metabolism. Major related themes covered include the assessment of the 'mineral value' of feeds, the false hopes placed on organic mineral supplements and limiting the 'mineral footprint' of livestock production to lower environmental pollution. Also discussed are new developments and concepts including: Salt tolerance and optimizing production in salt-rich environments. Use of phytase rather than phosphate supplements in pig and poultry rations. Demineralization of the skeleton during confinement. Recognition of sub-acute, clinical hypocalcaemia as a disorder in dairy cows. The assay of 'free' plasma B12 to assess cobalt status of cattle. Limitations of cell culture and ligated loop techniques for assessing bioavailability. Following a clear and easy to reference structure, the book also considers potential pitfalls, such as misleading estimates of mineral requirements for growth, and misinterpretation of genomic markers for mineral requirements and bioavailability of supplements. An essential resource for researchers and students in animal nutrition, agriculture and veterinary medicine, this book also forms a useful reference for veterinary practitioners and those concerned with human nutrition and environmental protection.

Harvested Forages deals with the subject of food for domestic animal feeding. Such food is called "forage" and includes things like alfalfa and other plants usually referred to as "hay." Topics include the ways that this forage is produced, how it is harvested, and ways that it should be stored. Other issues that are dealt with include various criteria and measurement procedures for assessing forage nutritive quality, potential health hazards associated with particular plants and plant toxins, and various issues of plant growth, pest control, and soil fertility--among other topics. This book is essential for any institution with a strong program in range sciences, animal sciences, animal feeding and nutrition, and related programs.
Key Features
* Synthesizes and summarizes a vast and widely dispersed literature in animal science
* Serves as a reference for managers of harvested forages as well as all those involved with the forage production industry

Today, due to the high population of human beings, scientists are increasingly concerned with food shortages and searching for alternative sources of dietary protein, such as algae, insects, and worms. Spirulina represents a superior alternative source, as it has a high nutrient content without toxicity, and can be reared in many countries worldwide. Given the limited amount of studies on the advantages and disadvantages of using Spirulina in birds' diets, this book fills an important research gap. It highlights the nutritional aspects of using Spirulina in poultry diets, and will appeal to animal husbandry and veterinary students, professors, feed formulators, poultry production consultants and farmers.
