The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. - With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far - Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors - Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research

This book contains conference proceedings of the 28th Poultry Science Symposium of the World's Poultry Science Association held in Bristol, UK, in September 2005. It focuses on the discontinued use of antibiotics in poultry and on the interactions between the birds, dietary factors and pathogens. The 23 chapters include the history, current use and legislative aspects of feed additives in the European Union; poultry nutrition without antibiotics; early development of the small intestinal function; absorptive function of the small intestine; epithelial structure and function of the hen intestine; immunological development of the gut; molecular approaches to the analysis of the gastrointestinal microbial ecosystems; microbial flora of the chicken digestive tract; mechanisms of pathogen control in the digestive tract; effect of nonstarch polysaccharidases on gastrointestinal function; effects of amino acid and protein supply on nutrition and health; the role of feed processing on gastrointestinal function and health in poultry; the causes, prevention and the role of nutrition in the production of wet litter; influence of gut health and immunity on micronutrient supply; virus-induced gastrointestinal diseases of chickens and turkeys; the digestive tract as an entry point for bacterial infections; Eimeria spp. genetics, protection and antigen identification; developments and constraints of feed acidification in controlling gut pathogens in poultry, with an emphasis on Salmonella spp., competitive exclusion in poultry production; Campylobacter spp. and their bacteriophages in poultry; breeding for disease resistance; The EU perspective on the monitoring of zoonoses and zoonotic agents and the significance of gastrointestinal problems to poultry farmers. This book will be of interest to researchers in food science and veterinary medicine, decision makers and poultry farmers.

This collection summarises current research on the composition and function of the gastrointestinal tract in poultry, the factors that affect its function, and nutritional strategies to optimise poultry nutrition, health and environmental impact. Part 1 begins by summarising advances in sequencing and omics technologies to understand gut function. It then reviews our current understanding of the gut microbiota, the development of the gut microbiome over the life of the bird, and gut function in nutrient processing and immune response. The second part of the book reviews what we know about factors affecting gut function and health. Chapters cover gastrointestinal diseases, the interaction between pathogens and the gut as well the impact of antibiotics. The final group of chapters discuss current research on the effectiveness of feed additives in optimising gut health, including probiotics, prebiotics, synbiotics, antimicrobials, essential oils and other botanicals as well as cereal grains. With its distinguished editor and team of expert chapter authors, this will be a standard reference for poultry scientists, poultry feed manufacturers and the poultry farming community.

Poultry are the most widely used animal protein source in the world: billions of meat birds are produced globally each year, using 360 million tonnes of feed. Within Europe, over 30,000 companies involved in the production of poultry create an annual turnover of €107 billion. However, maintaining the sustainability of the industry as it moves towards antibiotic-free production is one of the key challenges. Starting with an overview of antibiotics as growth promoters and the challenges faced as the industry moves away from their use, this book then thoroughly considers the potential of pre and probiotic additives in poultry gut health. Based on the renowned World Poultry Science Association UK Branch Poultry Science Symposium 2022, this book provides a thorough and valuable contribution to the field for all involved with the nutrition and production of poultry.

Poultry are a major source of valuable high-quality protein for much of the world's population, so food security is heavily dependent on maintaining poultry health. They are also increasingly important as specialist hobby animals in back-yard flocks. Despite this, veterinarians specializing in the care and health of these important domestic animals are few and far between, and many vets in small animal practice have little real experience of poultry health management and disease. Providing a comprehensive overview, this new handbook will help to plug this gap with 46 chapters of practical and accessible poultry health and management. Written by international experts, this book forms a valuable illustrated resource for veterinary professionals, veterinary students, or those entering the poultry industry.

This work sheds new light on the interplay between the gut, gut microbiota, and host physiological processes in production animals. The gut microbiome shapes health and susceptibility to disease and has become a leading area of research in the animal sciences. Gut health encompasses a number of physiological and functional features. Nutrient digestion and absorption, host metabolism and energy generation, a stable microbiome, mucus layer development, barrier function, and mucosal immune responses; all of which are required to interact to make an animal perform physiologically and according to its greatest genetic potential. This carefully presented book broadens our vision, approach and results on gut health and the ability to regulate animal production. Understanding the chemistry of microbiomes has broad implications, including providing functional annotations for the microbial genomes, insights into the chemical languages that link microbes to each other and to their host, and translational implications for precision veterinary medicine, environmental health, and sustainable animal agriculture and welfare. Experts working in microbiome research, host immunity, and animal production, veterinarians and researchers in livestock science will understand the great importance of this volume.

Recent interest in how poultry are housed and managed in order to ensure profitability, sustainability, and good levels of animal welfare, are challenging issues that commercial poultry keepers face, particularly where legislation is bringing about legal requirements for housing. This book compares and contrasts alternative housing with conventional and traditional systems for commercial poultry (laying hens, meat chickens, turkeys, waterfowl and gamebirds) with regards to welfare, disease, health, nutrition, sustainability and genotype-environment interaction. It is suitable for researchers and students in poultry science. .
