This collection features five peer-reviewed reviews on optimising pig nutrition. The first chapter considers advances in nutritional requirements and metabolism and how these contribute to the sustainable production of pig meat, including the need to maintain sow body condition throughout gestation and lactation and ways of reducing variation in pork production systems. The second chapter discusses the essential contribution of balanced energy and protein levels in achieving optimal health in pigs. It includes a case study which illustrates how characteristics of feed form and structure may have contradictory impacts on the gastric health and performance of pigs. The third chapter summarises current knowledge on the effects of prebiotic oligosaccharides on porcine gut function and health, focussing on the effects on gut functions in the early postnatal phase. The fourth chapter addresses recent advances in understanding the role of vitamins in porcine diets. It outlines their importance for some aspects of oxidative mechanisms, including the development and competence of the immune system. The final chapter summarises the nutritional attributes of macroalgae in terms of macro and micronutrients as a source of protein and other compounds in pig nutrition.

"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.
