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
In response to concerns about animal welfare, food assurance schemes are now incorporating standards for animal welfare. This is particularly important in the poultry industry, where much attention has focused on the welfare of broilers (meat birds). However, there is as a result a greater need for scientifically-based methods for the measurement and auditing of welfare. This book brings together papers by international experts from the academic, professional and industrial sectors. It examines practical ways of measuring and auditing broiler welfare on-farm, during transit and pre-slaughter. Related marketing issues and future developments such as automation, are also discussed.
Advances in Poultry Welfare provides a targeted overview of contemporary developments in poultry welfare. The reviews in the volume address topical issues related to poultry welfare research and assessment, with a focus on identifying practical strategies for improvement as well as information gaps that remain to be filled. Part One provides an introduction to poultry production systems and gives a broad overview of current poultry welfare issues. Part Two moves on to review several aspects of poultry management, focusing on hatchery practices, early rearing, and slaughter. Part Three deals with welfare assessment on the farm, while Part Four explores continuing challenges, such as feather pecking and skeletal problems. This is followed in Part Five by a discussion of emerging issues, with chapters covering alternative parasite control methods, backyard poultry production, mass depopulation, and genetic approaches to reducing the impact of environmental stressors on welfare. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs, and poultry. With its expert editor and international team of contributors, Advances in Poultry Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of poultry. Provides in-depth reviews of emerging topics, research and applications in poultry welfare Integral part of a wider series, Advances in Agricultural Animal Welfare, which will provide comprehensive coverage of animal welfare of the world’s major farmed animals Covers a range of topical issues within the field, from beak-trimming and skeletal problems, to early rearing and the design and management of poultry production systems Edited by a distinguished leader in the field
Part 1 of this volume reviews advances in research on key aspects of poultry behaviour and welfare monitoring. Part 2 discusses particular welfare issues affecting broilers and layers such as housing and environmental enrichment as well as problems such as injurious pecking and bone health.
This comprehensive research book represents the first complete integration of current knowledge in this area. It addresses issues associated with poultry breeding particularly by examining quantitative and molecular genetics and the uses of transgenic technology. A special section covers the important area of disease resistance and transmission.
Broiler breeder chickens are the parent stock used to produce broiler chickens raised for human consumption and have long been caught in a welfare dilemma. The immensely successful selection of fast-growing meat-type chickens over the last 80 years has created a remarkably efficient meat-producer and given us access to cheap chicken meat but has also created health problems for the animals. These problems especially affect the breeder generation, which must be raised with strict feed restriction to limit weight gain and thus maintain physical health and normal fertility. At the same time, however, feed restriction causes chronic hunger and feeding frustration with reduced animal welfare as a result. In the EU alone 60 million breeders are affected annually and although the problem is well-known within the industry, there is financial incentive to keep selecting for even higher growth potential in broilers, further increasing the problems for broiler breeders. Many strategies for reducing the impact of growth restriction on breeder welfare have been suggested and are usually aimed at somehow increasing the amount of feed given at feeding times. This can be done either through adding bulky fibers to the diet or by reducing feeding frequency. In this thesis, focus is on the latter as we explore the effects of intermittent fasting (IF) on the welfare of young broiler breeders as well as wild-type Red Junglefowl. Intermittent fasting, or “skip-a-day” feeding, is supposedly the most common feeding strategy for broiler breeders worldwide but is perceived as welfare-reducing and thus illegal in Sweden and several other European countries. In spite of this, the scientific knowledge of how this type of feeding affects chicken welfare is scarce. Assessing the overall effect of IF on breeder welfare is complicated by large variations in both physiological and behavioral parameters between feeding and fasting days, but it does appear that chicken welfare is improved at least on the feeding days of IF regimens. It also seems that some of the health benefits reported from mammalian studies of IF may apply to chickens as well, although behavioral indicators still point to welfare issues unless the level of feed restriction can be relaxed. In comparison with daily feed restriction, IF appears to increase the motivation for feed consumption but to reduce the motivation for appetitive behaviors such as foraging, which may explain why birds fed on this type of schedule are often reported as calmer.
This authoritative textbook provides an introduction and guide to poultry behavior and welfare. It describes the origin and biology of the various species of bird that are of agricultural importance, as well as giving a succinct overview of their key behavior patterns. There is careful discussion of the many factors that influence their welfare, and detailed consideration of the ways in which legislation and commercial interests interact in an attempt to satisfy the many needs involved. The final chapters discuss possible future developments within the subject. The book is in part an update of a previous work, Poultry Production Systems: Behaviour, Management and Welfare (CABI, 1992), completely rewritten and with much new material added.
