Advances in Pig Welfare, Second Edition continues its complete coverage of key areas of pig welfare assessment, management and improvement.  The book covers both recent developments and reviews of historical welfare issues, with 12 new chapters addressing the most relevant and significant issues from a global perspective. Sections review the needs of pigs, including chapters on the physical environment and the social and emotional needs of the animals, key welfare issues in the pig’s lifecycle from birth to slaughter, including weaning, aggression and pig-human interactions, and emerging topics such as prenatal stress, individual differences and organic farming. Final sections cover pig welfare and attitudes towards pig welfare amongst farmers and other stakeholders. Written by an international team of leaders in the field, the book continues to be a useful resource for practicing vets involved in welfare assessment, welfare research scientists and students, and indeed anyone with a professional interest in the welfare of pigs.

This collection features four peer-reviewed reviews on improving the welfare of gilts and sows. The first chapter reviews current knowledge on the factors affecting the health and welfare of gilts and sows during pregnancy and parturition. The chapter considers the influence of group housing, stress and social interaction on the development of production diseases, such as post-partum dysgalactia syndrome and porcine reproductive and respiratory syndrome. The second chapter provides a detailed overview of the factors affecting the welfare of pigs during breeding and gestation. The chapter considers the influence of modern pig production on animal behaviour and welfare and reviews to what extent the inability to form matriarchal groupings contributes to demonstrations of aggressive behaviour. The third chapter concentrates on the managerial and environmental interventions that attempt to reconcile the behavioural and physiological needs of both the sow and piglets to optimise their welfare during farrowing and lactation. The final chapter describes the welfare issues associated with individual confinement systems and examines the nature and significance of stereotyped behaviour in gestating sows. The chapter also addresses the issue of hunger in the pregnant sow and drivers to adopt group housing systems for pregnant sows.

This collection features four peer-reviewed literature reviews on improving piglet welfare. The first chapter reviews the main welfare challenges faced during farrowing and lactation, including the occurrence of painful husbandry procedures, such as tooth resection, tail docking and castration. The chapter also highlights various mitigation strategies that can be implemented to optimise the welfare of both sows and piglets in the farrowing environment. The second chapter addresses some of the main welfare concerns that can arise during the weaning and nursery stage as a result of separation between piglet and sow and exposure to a new environment. The chapter also summarises the most important fields of environmental, nutritional and social stress and how these experiences can be mitigated with the correct strategies. The third chapter considers the demand for improved welfare and animal handling systems from governments, non-governmental organisations and consumers. The chapter reviews recent advancements in technology that have the potential to improve animal wellbeing, profitability and performance during the weaning period. The final chapter discusses the main etiological agents acting in the period of transition from weaning, the risk factors for their introduction and diffusion within the farm and the main measures available for their control.

With growing concern from consumers and regulatory agencies about the welfare of farmed animals such as pigs, the livestock sector must assess how animal welfare can be improved whilst ensuring livestock production remains economically and environmentally sustainable. Understanding the behaviour and improving the welfare of pigs is a comprehensive review of key research in this important area. This collection reviews genetic and developmental factors affecting pig behaviour and current welfare issues at different production stages, as well as specific issues such as tail biting and castration. The book concludes with an assessment of ways to measure welfare, including techniques to monitor pig behaviour. With its distinguished editor and international team of expert authors, Understanding the behaviour and improving the welfare of pigs will be a standard text for university researchers in pig/swine and veterinary science as well as ethology. It will also be a key reference for government and other agencies involved in regulating and monitoring farm animal welfare, as well as farmers and companies involved in pig production.
