This collection features four peer-reviewed reviews on viral diseases affecting pigs. The first chapter summarises recent research on the causes and epidemiology of major bacteria, viruses and parasites found in pig production, focussing on those with a particular impact on safety and global production, such as African swine fever, Porcine Reproductive and Respiratory Syndrome (PRRS) and Porcine Epidemic Diarrhoea (PED). The second chapter reviews advances in understanding mechanisms of porcine viral disease transmission and pathogenesis. The chapter concludes with commonly used measures for prevention and control of viral diseases of pigs, emphasizing the importance of the vaccination programs as cornerstone of swine health programs. The third chapter discusses our current understanding of the mechanisms of resistance to the major respiratory diseases affecting pigs, including PRRS. The chapter considers the use of marker-selection and genetic modification as mechanisms to prevent the infection of PRRS and reduce its impact on swine health. The final chapter considers the transmission, clinical presentation, evolution and spread of two major diseases affecting swine production - PRRS and PED. The chapter reviews the impact of each virus on a global scale, as well as its impact on swine production in the United Kingdom.

'...individual chapters provide very thorough, up-to-date reviews of health and welfare of pigs during different stages of production...The health section does a good job of summarizing the current major disease challenges facing pig production...If you want up-to-date reviews on some of the most pressing welfare issues in different stages of production, there are some good chapters included.' Animal Welfare 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. This volume looks at animal health and welfare. Part 1 reviews the main diseases affecting pigs as well as ways of managing diseases and boosting pig immune function. Part 2 reviews what we know about pig behaviour and appropriate welfare standards. It also assesses the welfare of different groups of pigs, from gilts and sows to weaned piglets and finishing pigs, as well as transport, lairage and slaughter. With its distinguished editor and international team of expert authors, this will be a standard reference for researchers in swine science, 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 breeding and nutrition.
