According to the results, the optimal density was 1.2 m2/pig considering welfare and building utilization.

The reduction in infectious agents in the air by the EPI technology could potentially decrease the microbial exposure for pigs.

This trial showed the advantage, in an environmental point of view, to use 15% drainage openings on the solid part of partly slatted floors in pens for group-housed gestating sows.

The influence of feed structure and pelleting on the development of gastric ulcers in pigs is well established. Some studies have shown a beneficial effect of access to straw on gastric health. However, the role of other factors, e.g. disease and stress, is not well understood.
