The scope of book has relevant and important informations on some of the popular tamed birds reared as pet in cages. Among these Parrots and Mayana are companion species capable of learning and limited conversation with members of the house. Bulbul, partridges and pigeon are used for sports. Owners of these birds expect guidance for care and management from the experts of poultry science because so far there appears to be no school on the management of such avian species. Incorporation of these avian species in the book is expected to enrich the knowledge of students and teachers of the Avian and Poultry Science. Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

A symposium held in 1973 chaired and organized by William R. Dawson was the first major attempt to summarize and synthesize the existing information in the then emerging field of avian energetics. The symposium featured papers by James R. King, William A. Calder III, Vance A. Tucker, and Robert E. Ricklefs and com mentaries by George A. Bartholomew, S. Charles Kendeigh, and Eugene P. Odum. The proceedings of the symposium, Avian Energetics (Paynter 1974), played a critical role in stimulating interest and research in the field of avian energetics. Some twenty-odd years later, we are making another attempt to summarize the information in the field of avian energetics. Some obvious differences exist be tween its predecessor and this volume. Numerous improvements in methodology, such as the use of doubly labeled water to estimate metabolism in free-living birds, now allow researchers to ask questions that could not be addressed previ ously. Second, consideration of nutrition is now inseparable from that of energet ics. This merger is necessary not only because food intake is the source of both en ergy and nutrients but also because one or more nutrients, rather than energy, can be limiting for a given species in a particular instance. Finally, the study of ener getics and nutritional ecology, particularly in birds and mammals, has grown so dramatically that a single volume can now only partially cover the range of possi ble topics and can catalogue only a sampling of all the studies on the subject.

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.

Commercial poultry production is associated with various types of stress leading to decrease of productive and reproductive performance and compromised health of growing chickens, parent birds as well as commercial layers. Stress adaptation is associated with various signaling pathways and is executed at the gene level. The term vitagenes refers to a group of redox-sensitive genes that are involved in stress sensing and preserving cellular adaptive homeostasis. The vitagene family includes heat shock proteins, superoxide dismutase, glutathione and thioredoxin systems and sirtuins. The vitagenes are key players in redox signaling and redox homeostasis maintenance in birds, including poultry under commercial stress conditions of egg and meat production. Development of the vitagene concept become an important milestone in understanding molecular mechanisms of adaptation to stress. The goal of this book is to provide up to date information about the roles of vitagenes in avian biology and poultry health. Special emphasis is put on the role of vitagenes as an essential part of the redox homeostasis maintenance, stress adaptation, and development of adaptive homeostasis. The book provides data to indicate that nutritional modulation of vitagenes is a new direction in nutritional sciences. Practical results of the successful usage of the vitagene concept in poultry production are also presented. This book is intended to be of practical importance to avian/animal scientists, poultry producers, to nutritionists and vets, students of biological and agricultural colleges and universities. It can also be interesting for researchers in areas related to physiology, biochemistry, nutrition, ecology, environmental sciences, evolutionary biology, etc.

Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in humans, farm animals and poultry through its incorporation into a range of selenoproteins. Low Se content in main feed ingredients is a common problem worldwide and dietary Se supplementation is a current practise in poultry and farm animal nutrition. Recent research clearly proved that sodium selenite, used for the last 40 years as a feed supplement, is not an optimal form of Se. However, use of organic selenium in animal/poultry diets can help meeting Se requirement and maintain high immunocompetence, productive and reproductive performance. The goal of this book is to provide up to date information about the roles of Se in poultry nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. Se in feed and organic Se are characterised in detail with emphasis to selenomethionine as a storage form of Se in the body. Also specific Se-deficiency related diseases in poultry are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. A link between poultry industry and human health via production of Se-eggs and Se-enriched meat is shown. This book will be of practical importance to poultry producers, to nutritionists and vets as well as for avian/animal scientists, students of agricultural colleges and universities. It will also be of interest for researchers in areas related to ecology, environmental sciences, evolutionary biology, etc.
