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 five peer-reviewed literature reviews on ensuring animal welfare during transport and slaughter. The first chapter examines the impact of transport on beef and dairy cattle, as well as the effects of transport on carcass quality issues, such as bruising and dark cutting beef. It details how conditions can be optimised to ensure the welfare needs of the animal are met during all stages of transport. The second chapter reviews the legislation and codes of practice surrounding the transport and slaughter of cows to be culled as a result of disease or the development of health conditions such as lameness. The third chapter considers the effects of transport, handling and slaughter practices on pigs as well as physiological effects on carcass and meat quality. The fourth chapter explores current approaches used to stun poultry before slaughter, including electrical stunning and controlled atmosphere stunning. The chapter reviews the associated risks and benefits of each approach to overall bird health and welfare. The final chapter reviews the main welfare issues associated with management of sheep once they leave the farm, including transport by road and sea, use of holding facilities as well as handling and stunning of sheep at abattoirs.
