Chickens are by far the world’s most widely farmed animal, kept for both meat and egg production. They are at the centre of many debates regarding housing and production systems, causing significant interest in what lies behind chicken behaviour. This accessible book covers sensory biology, behavioural development, preferences and aversions, social behaviour, learning and cognition, behavioural issues in different systems and solutions for behavioural problems. Authored by an authority on chicken ethology, it brings together the fields of animal behaviour, neuroscience, psychology and epidemiology to provide a comprehensive understanding of chicken behaviour and help improve the lives of farmed chickens around the world.

Many behaviors in poultry can be modified by genetic selection. Selection of laying hens for maximum egg production had the unfortunate side effect of increased rates of beak inflicted damage on other birds. Selective breeding has eliminated broodiness and has either increased or decreased other behaviors, such as hysteria, fearfulness, appetite in broilers, social dominance, ability and damage to other birds. Genetic selection can be used to reduce behaviors that cause welfare problems. However, it must be approached with caution to avoid unintended consequences that would be detrimental to welfare. A calm, docile bird that appears behaviorally calm, may take longer for its heart rate to return to normal after it is frightened. The use of group selection instead of single-bird selection can be effectively used to reduce undesirable behaviors such as feather pecking and to maintain high egg production. An entire group of birds is selected instead of selecting individuals.

Genetics and the Behavior of Domestic Animals, Third Edition offers the latest and most valuable information on animal science and behavioral genetics, carrying on the book’s legacy since its original publication in 1998. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. Genetics and the Behavior of Domestic Animals, Third Edition is the most valuable resource for researchers and practitioners in animal and veterinary science, animal behavior, genetics, ethology, and similar fields. Advanced undergraduate and graduate students in these disciplines will also benefit from the global expertise featured in this newest edition. Provides full and thorough updates to all chapters, ensuring dissemination of the latest data and research Synthesizes research from behavioral genetics, animal science, and veterinary literature Broaches fields of behavior genetics and behavioral research Includes practical applications of principles discovered by behavioral genetics researchers Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats

In these classic experiments, quail chicks were selectively bred for the behavioral traits of fear and social reinstatement. Over a period of 20 generations, four separate genetic lines were created. They were high and low fear and high and low social re-instatement. The duration of tonic immobility was used as a measure of fear and social reinstatement was measured with a treadmill test. In this test, the time that a bird will walk on a treadmill to stay close to its flockmates is measured. Since the publication of this chapter in 1998, many scientists have carried out with these genetic lines. Duration of tonic immobility does not all measure all types of fear. Fear maybe multidimensional because selection for tonic immobility has little effect on behavioral reactions to novelty. More recent research has also discovered linked traits such as low social reinstatement birds have stronger ultradiam rhythms.

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.

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.

Commercial Chicken Meat and Egg Production is the 5th edition of a highly successful book first authored by Dr. Mack O. North in 1972, updated in 1978 and 1984. The 4th edition was co-authored with Donald D. Bell in 1990. The book has achieved international success as a reference for students and commercial poultry and egg producers in every major poultry producing country in the world. The 5th edition is essential reading for students preparing to enter the poultry industry, for owners and managers of existing poultry companies and for scientists who need a major source of scientifically based material on poultry management. In earlier editions, the authors emphasized the chicken and its management. The 5th edition, with the emphasis shifted to the commercial business of managing poultry, contains over 75% new material. The contributions of 14 new authors make this new edition the most comprehensive such book available. Since extensive references are made to the international aspects of poultry management, all data are presented in both the Imperial and Metric form. Over 300 tables and 250 photos and figures support 62 chapters of text. New areas include processing of poultry and eggs with thorough discussions of food safety and further processing. The business of maintaining poultry is discussed in chapters on economics, model production firms, the use of computers, and record keeping. Updated topics include: breeders and hatchery operations; broiler and layer flock management; replacement programs and management of replacements; nutrition; and flock health. New chapters address flock behavior, ventilation, waste management, egg quality and egg breakage. Other new features include a list of more than 400 references and a Master List of the tables, figures, manufacturers of equipment and supplies, research institutions, books and periodicals, breeders, and trade associations. Commercial growers will find the tables of data of particular interest; scientists will be able to utilize the extensive references and to relate their areas of interest to the commercial industry's applications; and students will find that the division of the book into 11 distinct sections, with multiple chapters in each, will make the text especially useful.
