The regulation for the keeping of pigs from 1988 acknowledges in principle only results of research, induced by long term problems in pig husbandry. Therefore it is only relevant for problems, that became apparent at least ten years earlier. Group housing for sows is not taken into consideration in the regulation. However, in the near future veterinarians will be expected to produce an opinion about the welfare of sows kept in group housing systems. In the houses for pregnant sows and in the ones for farrowing sows and for sows with piglets, problems can be expected resulting from group housing. Practice is not always according the nice theory, telling us, that sows want a place on their own for farrowing. Thus it can be difficult to end up with one sow in one farrowing nest. If piglets leave the farrowing nest to early, they will not be able to recognize their own sow amidst the group of others. This results in "multisuckling", with its large number of runts. However, group housing expects every piglet to stay with its own sow. In considering the welfare of sows kept in group housing systems a veterinarian will have to ask himself again and again, whether the sows are able to cope with the presented situation. The same counts for the piglets.
