A comprehensive review of all aspects of commercial production systems, this book provides an up-to-date look at all aspects of broiler breeder production and management, starting with specialized genetic programs as developed by the primary breeders and ending with two chapters on very practical, hands-on aspects of breeder management, including extensive coverage of health management, feeding systems, environmental control, lighting programs and all aspects of male and female reproduction. Recognizing the diversity of management systems worldwide, the authors have included breeders in both temperate and warm climates and also for controlled environment vs.curtain-sided housing systems. This unique publication is an essential reference for all professionals involved in broiler breeder production.
"Poultry meat is the most important animal protein source in the human diet. As a consequence, global production of broiler meat is rapidly growing and now more than 125 million metric tonnes. A relatively small number of broiler breeders has a major impact on the whole poultry meat chain. The continuing increase in the genetic potential of broilers makes the production of first-class chicks increasingly challenging. State-of-the-art management is crucial for a successful flock. Differences in results up to 10 day-old chickes per hen house are not rare, costing tens of thousands of euros. Breeder Signals contains practical information about broiler breeders to ensure maximum production of first grade hating eggs. This book also offers practical tools and modern insights to optimise sexual behavior, fertility, egg production, and hatchibility, based on the look-think-act approach. Feathering provides you with signals about the quality of your flock. Too nice? Then they are hardly mating. Too little? These hens will not mate since it will be painful. The book follows the day-old-chick arriving at the rearing house through the laying period and up to egg transport to the hatchery. Breeder Signals is essential for anyone working in the poultry meat chain as breeder farm managers, farm workers, advisors, veterinarians, students, etc." -- from back cover.
Research on chemical communication in animals is in a very active and exciting phase; more species are studied, data are accumulating, concepts are changing, and practical application seems feasible. While most of the work on chemical ecology and chemical sig nals deals with insects, vertebrate communication provides a formidable challenge and progress has been slow. Joint efforts and frequent direct contacts of ecologists, behaviorists, psychologists, physiologists, histologists and chemists are required. Such an interdisciplinary exchange of information took place on the occasion of the Symposium on Chemical Signals in Vertebrates and Aquatic Animals in Syracuse, New York, from May 31 to June 2, 1979. More than one hundred investigators from seven countries participated, and the papers presented comprise this volume. Since the first Symposium on Vertebrate Chemical Signals at Saratoga Springs in 1976, considerable progress has been made with field studies, the physiology of the vomeronasal organ, and its role in reproductive behavior. The behavioral functions and chemi cal nature of priming pheromones are better understood. Efforts to isolate and identify mammalian pheromones are gaining ground, and the bioassays are becoming more sophisticated. In addition to formal presentations, one evening of the Symposi um was devoted to round-table discussions of particular topics. The selected themes indicate the "growing points" of chemical communi cation research: priming pheromones, vomeronasal organ, bioassay, and practical applications.
The Nonproliferation Predicament is an authoritative and comprehensive look at U.S. nonprolif-eration policy. Top U.S. scholars, analysts, and policymakers focus on the period since the Reagan administration took office and address several questions about the current state of nuclear proliferation: As the international non-proliferation regime evolves will it continue to be responsive to the problem of proliferation? Or will it become superannuated by new technologies, or enmeshed in domestic and international political controversies and conflicting interests? What nonproliferation policies are likely to be effective in the 1980s and beyond, as nations continue efforts to establish and expand nuclear industrial bases, providing them with capabilities useful for the pursuit of weapons options in the future? Does the stagnation of the international nuclear market and the difficulties of nuclear threshold states like India give reasons for hope? Or will the limited proliferation of the past prove to have been a passing anomaly in military history?
Broiler Chickens is a short practical book of guidelines and advice to good welfare practice in broiler chicken farming. With contributions from world expert researchers in poultry welfare, this book distils academic research into applied advice on the farm for industry and farm workers. The content covered includes health and disease impacts with a One Health focus, housing for optimal health, broiler breeders, hatchery management, broiler slaughter practices, transport, animal welfare assessment measures and a discussion of welfare improvement measures on the farm. 5m Books
This book explores how daily and seasonal rhythmicity is generated, how these rhythms are synchronised by our environment, and how they regulate the neuroendocrine systems that impact our physiology and behaviour. The constraints of surviving in a seasonal environment have shaped human evolution and migration, have shaped our societies and cultures, and continue to influence our everyday lives, health and wellbeing. Identifying the mechanisms whereby seasonal rhythmicity is generated and regulates the brain and body is not only important for understanding the natural world and relevant to animal production, it also offers many insights into the human condition. Each chapter is written by an international expert in the field of chronobiology. A historical perspective on how research into photoperiodism and rhythmicity progressed is initially provided, but the main focus of this book is on the remarkable studies in the last few decades that have unravelled the molecular and cellular machinery underpinning circadian and circannual timing. Topics covered include the role of melatonin in communicating seasonal information to the brain and pituitary gland, the neuroanatomical pathways in mammals, birds and fish by which changes in photoperiod reach the hypothalamus, the role of glial cells (tanycytes) and thyroid hormone in seasonal rhythmicity, neuroplasticity across seasons, effects of changing day length on mood, regulation of “clock“ gene expression, and the role of the suprachiasmatic nucleus. This book will appeal to all students and researchers who wish to learn about current and past research on daily and seasonal rhythmicity. This is the tenth volume in the International Neuroendocrine Federation (INF) Masterclass in Neuroendocrinology series (Volumes 1-7 published by Wiley) that aims to illustrate highest standards and encourage the use of the latest technologies in basic and clinical research and hopes to provide inspiration for further exploration into the exciting field of neuroendocrinology.
Three invited international experts present overviews of recent developments in key fields and will submit chapters for the book. Jane Hurst from Liverpool University in the UK presents an overview on the function, mechanisms and evolution of chemical signals, Penelope Hawkins from the University of Western Australia will detail the importance of male odors in female mate-choice and the priming of female reproduction, and Francesco Bonadonna from CNRS-CEFE, Montpellier in France presents an overview of the importance of chemical signals for the formation and maintenance of pair-bonds, parent – offspring recognition and navigation in seabirds. Select submissions are invited by the scientific committee to contribute chapters. ​
