As well as providing sufficient space for sows in group housing, the quality of the space provided should not be overlooked. Quality flooring is important to prevent slipping and provide a comfortable lying areas. The comfort of a lying area can be improved by using rubber flooring, providing bedding such as straw, or providing an area of solid flooring rather than slatted. Including barriers in the pen design can allow sows to avoid aggression from other group members, and promote the formation of subgroups by promoting group lying.Finally, enrichment can help sows express normal behaviour, with straw being a good option.
