This collection features four peer-reviewed reviews on developing immunity in poultry. The first chapter discusses the advances in genetic, genomic and functional genomic studies of immune and disease resistance in chickens. The chapter reviews multi-trait selection experiments and considers the potential trade-offs between production and immunocompetence in response to disease. The second chapter reviews the importance of the gut microbiome in optimising animal health and reducing susceptibility to major diseases affecting poultry production. The chapter examines intestinal immunity, as well as the microbiota interactions which occur within the poultry immune system. The third chapter addresses the nutritional strategies which can be implemented to boost immune function in poultry. The chapter considers the process of nutritional modulation and reviews the use of vitamins, minerals and amino acids to enhance, suppress and balance poultry immune systems. The final chapter provides an overview of the avian defence system and its role in tackling some of the major pathogens affecting global poultry production, such as coccidiosis. The chapter reviews the various elements of the host defence system and considers how supplements can modulate the immune system and its responses to specific challenges.

"This book gives a good overall review of the advances that have recently occurred in the fields of poultry genetics and genomics...one thing that really struck me about this book was the calibre of the editorial team and the international range and expertise of the contributing authors. With over 550 pages this book is well worth its place on the bookshelf of anyone who is interested in poultry breeding and genomics."International Hatchery Practice The poultry breeding sector faces a number of challenges, including the need to produce more resilient breeds in the face of disease, antibiotic resistance, increasing consumer concerns about bird health and welfare and expectations of poultry meat and egg quality. Advances in poultry genetics and genomics provides a comprehensive review of the recent developments in poultry genetics, breeding and genomics, focussing on the improvement of functional traits to build resilience, the use of genomic selection and its application in breeding improved layers and broilers, as well as the sector's emerging trends such as epigenetics and genome editing. With its distinguished editor team and international range of expert contributors, Advances in poultry genetics and genomics will be a standard reference for poultry scientists, companies involved in poultry breeding and government agencies supporting the poultry sector.
