From the evaluation of welfare and economic performance of systems described in this paper, the designed pen appears to offer the best indoor alternative to conventional farrowing crates. However, it is important to make efforts to refine these systems as there are still concerns, particularly regarding safety and ease of operation, and robustness to variability in maternal behaviour. Research into physical attributes of the systems that can facilitate the former and biological strategies (e.g. breeding for better maternal behaviour) to target the latter are important on-going objectives. In addition, to futureproof systems for a developing pig industry and uncertain market, additional research is needed to determine the environmental impact of certain systems and their economic feasibility in a national and international market place.
