Animal welfare is attracting increasing interest worldwide, especially in developed countries where the knowledge and resources are available to (at least potentially) provide better management systems for farm animals, as well as companion, zoo and laboratory animals. The key requirements for adequate food, water, a suitable environment, appropriate companionship and good health are important for animals kept for all of these purposes. There has been increased attention given to farm animal welfare in many co- tries in recent years. This derives largely from the fact that the relentless pursuit of nancial reward and ef ciency, to satisfy market demands, has led to the devel- ment of intensive animal production systems that challenge the conscience of many consumers in those countries. In developing countries, human survival is still a daily uncertainty, so that p- vision for animal welfare has to be balanced against human needs. Animal welfare is usually a priority only if it supports the output of the animal, be it food, work, clothing, sport or companionship. In principle the welfare needs of both humans and animals can be provided for, in both developing and developed countries, if resources are properly husbanded. In reality, however, the inequitable division of the world's riches creates physical and psychological poverty for humans and a- mals alike in many parts of the world.

Since publication of the first edition of this book, public concern for the well-being of animals has continued to increase throughout the world. In addition, advances in research over the past decade have yielded an enormous amount of knowledge about animal mental health and wellbeing. Studies on animal stress, distress, emotions, psychological trauma, and mental disorders have brought to light insights on how to care for and treat the animal mind. The second edition is: Fully revised, expanded, and comprehensively updated with the most current knowledge about the full array of mental health issues seen in animals. Written by key opinion leaders, internationally-recognized experts and specialists. Comprehensive in its coverage, from the basic principles of mental wellness, emotional distress, suffering and mental illness, through to measurement and treatment. Packed with even more practical information, wisdom and clinical tips. This book remains invaluable to veterinary professionals, animal welfare researchers and advocates, and other animal caregivers.

"Each chapter provides an overview of current knowledge on the topic in question, accompanied by an outline of advances in both scientific and applied fields. The chapters are written by twenty-five authors, all scientific experts in the subject discussed... In conclusion, Understanding the behaviour and improving the welfare of chickens is an expertly written, widely accessible book for all professionals in the field, which should provide increased understanding of chicken behaviour and welfare." (Animal Welfare - Universities Federation for Animal Welfare) With rising consumer concerns about the welfare of farm animals, such as chickens, there is a growing urgency for the livestock production sector to ensure that welfare standards are met throughout the supply chain, from breeding to slaughter. Understanding the behaviour and improving the welfare of chickens offers a comprehensive summary on the wealth of recent research completed on understanding chicken behaviour and discusses how best to use this rich body of knowledge to optimise welfare management of broilers and layers. This collection features expert insights into the use of wearable, video and acoustic technologies as a means of monitoring behaviour, as well as improving current welfare protocols. With its distinguished editor and team of leading experts in their fields, Understanding the behaviour and improving the welfare of chickens will be a standard text for university researchers in poultry and veterinary science as well as ethology. The book will also be an authoritative reference for government and other agencies responsible for the poultry sector and farm animal welfare, as well as companies involved in rearing chickens and processing poultry meat and eggs.
