This collection features five peer-reviewed literature reviews on poultry housing systems.The first chapter reviews current poultry housing systems and the recent emergence of enriched cages and cage-free systems. It explores the impact of conventional cages on bird health and welfare, looking primarily at bone health.The second chapter examines the impact of different housing systems on the safety and quality of eggs. It reviews how hen housing and flock management can affect indicator populations, foodborne pathogens and chemical contamination.The third chapter considers the relationship between housing conditions and management in the rearing and production of broilers. It reviews the major welfare issues related to the housing of broilers, including feed and water restriction.The fourth chapter discusses current environmental enrichment strategies implemented in poultry production. The chapter details the benefits of these strategies, as well as their role in contributing to more sustainable production models.The final chapter reviews current knowledge on perching behaviour of chickens, as well as the associated risks to bird health and welfare that arise with the use of elevated structures, such as keel bone damage.

This book features five peer-reviewed reviews on ensuring the welfare of broilers.The first chapter considers the range of factors that pose a significant threat to broiler welfare, focussing on the impact of fast-growing broilers and high stocking densities. The chapter reviews how these factors have been addressed within the European Union through the inclusion of two case studies. The second chapter builds on research covered in the first chapter and details the welfare issues that can arise as a result of intensively reared broiler flocks. The chapter discusses the development of leg disorders and lameness, as well as contact dermatitis.The third chapter reviews the major welfare issues related to the management of broiler breeders, including feed and water restriction, excisions and the potential for management strategies to have transgenerational effects.The fourth chapter similarly addresses the welfare issues that can arise in the housing of broiler breeders, but instead focusses on the impact of these factors on increased levels of aggression and consequent aggressive behaviour, such as feather-pecking.The final chapter explores the use of group-level technologies to monitor and automate poultry welfare assessments of broilers, focussing on the use of visual images retained from CCTV and video, as well as sound and temperature sensing.
