Abstract

Plasma-free corticosteroid concentrations, aggressive behaviour and levels of motivation to socially interact in a standard test were determined in two experiments. The two experiments used 32 and 40 pigs, respectively, and differences between experiments were to take into account the effects of neighbouring pigs between treatments (Experiment 1) and positional effects in the shed (Experiment 2). There were five treatments involving two types of housing (cage-stalls and tetherstalls), two designs of stall division (bars and mesh, that affected the level of aggressive behaviour between neighbouring pigs) and a control treatment of group-housed pigs. Pigs in tether-stalls separated by bars sho..
