This collection features four peer-reviewed reviews on alternatives to antibiotics in pig production. The first chapter provides a brief overview of antibiotic use in pig production and addresses the consequent development of antibiotic resistance. The chapter reviews recent advances in developing non-antibiotic means of controlling bacterial infections in swine, such as the use of phage therapy. The second chapter considers the use of prebiotics to optimise gut function in pigs. The chapter summarises current knowledge on the effects of prebiotic oligosaccharides on porcine gut function and health, as well as the modes of action of the commonly used prebiotics in pig production. The third chapter reviews advances in nutritional strategies to boost immune function in pigs, including the use of lipopolysaccharide to stimulate the immune system. The chapter considers the need to reduce the use of antimicrobials in swine diets and reviews the effect of dietary supplementation during key stages of a pig's life to enhance immunity. The final chapter reviews the microbiota of the gastrointestinal tract of the young pig and the important role it plays in the early stages of life. The chapter considers the use of probiotics and prebiotics in the post-weaning period of piglets to optimise gut function, animal health and performance.

This collection features four peer-reviewed literature reviews on developing immunity in pigs. The first chapter provides an overview of the latest research in gut function and immunity in pigs, as well as the role of the gut microbiota in shaping intestinal immune responses. The chapter also reviews recent advances in the development of novel tools to investigate the function of the pig gut. The second chapter describes the enteric and mucosal immune systems of pigs and presents evidence from experimental studies of the links between the immune system and microbiota. It examines the microbiome and metabolism of pigs and highlights its importance in the development of pig immune systems. The third chapter reviews advances in nutritional strategies to boost immune function in pigs, including the use of lipopolysaccharide to stimulate the immune system. The chapter considers the need to reduce the use of antimicrobials in swine diets and reviews the effect of dietary supplementation during key stages of a pig's life to enhance immunity. The final chapter assesses methods of improving gut function in pigs to optimise health, prevent pathogen colonization and optimise immunity. The chapter discusses research on genes associated with pathogen resistance and porcine immune response and reviews the role of dietary and nutritional strategies in preventing intestinal pathogen colonisation.

"What sets this book apart is its provision of such a comprehensive review of developments in pig nutrition as well as breeding. To do this it brings together some of the world's leading experts in this field of research to produce an unbiased, accurate and accessible guide to a critical part of pig production." The Pig Site Pig meat is the most widely-consumed meat in the world. Previous growth in production has relied, in part, on more intensive systems. In meeting rising demand, these systems face challenges such as the ongoing threat of zoonotic diseases, the need to improve feed efficiency in the face of rising costs, the need to reduce the environmental impact of pig production and increasing concerns about animal welfare. These challenges are addressed in the three volumes of Achieving sustainable production of pig meat. Volume 2 looks at pig breeding and nutrition. Part 1 starts by reviewing advances and constraints in conventional breeding, the development and use of molecular breeding techniques, as well as factors affecting functional traits such as reproductive and feed efficiency. The second part of the book looks at current research on meeting pig nutritional requirements, including understanding and modelling pig nutritional requirements to optimise feeding, as well as the role of vitamins, exogenous enzymes, growth promoters, prebiotics and probiotics. With its distinguished editor and international team of expert authors, this will be a standard reference for researchers in swine science as well as producers, government and other organisations involved in supporting pig production. It is accompanied by two companion volumes which focus on safety, quality and sustainability as well as animal health and welfare.
