title: [Keeping sows outdoors during the winter season].
abstract: During the last decade the number of outdoor breeding pig units increased in Northern Europe. With comparable results in reproduction and up to 70 per cent lower capital outlays in relation to the conventional indoor systems the interest of farmers in outdoor breeding grew also in Germany. There are a number of issues that are specific to outdoor systems that need to be considered during winter season.
