Welfare of pigs during finishing

Abstract

Finisher pigs, those of a post-weaning age kept for slaughter, make up the majority of the world pig population of approximately 1 billion. The intensive production system for post-weaned pigs is characterised by higher animal density, larger farms, use of concentrated foods and control of the production environment, particularly temperature, humidity and lighting. This chapter explores the relationship between nutrition management and the welfare of finishing pigs and the links between physical and social environment and welfare of finisher pigs. The chapter addresses the importance of environmental enrichment and ways to avoid tail-biting behaviour. Finally, the chapter describes methods of practical welfare assessment of finisher pigs and looks ahead to future research trends in this area.
