4 - Affective states and cognition in pigs

Abstract

In this chapter we will review the current knowledge and theoretical frameworks on affective states (i.e. short-term emotions and long-term mood) and personality in pigs and the influencing factors and methods of assessment as well as pigs’ cognitive capabilities, including their perception and processing of environmental information. A better understanding of affective states and cognition plays a key role in welfare assessment in pigs. Pigs’ physiological, behavioural, and cognitive reactions are intrinsically linked to their perception and processing of stimuli, as well as their memory. In particular, we will see that pigs possess a complex, high level of cognition in several domains, including a good understanding of their physical environment and important social cognition skills. These reflect the adaptation capacities of pigs to cope with diverse, complex, and changing physical and social environments. In the future, management and housing of pigs should increasingly consider their mental, psychological, and cognitive needs and capacities to allow them to express their species-specific goal-directed behaviours, thus matching their motivational needs, expectations, and desires.
