In addition, the importance of straw supply, to allow the sows to exhibit nest building behaviour was investigated. The present second contribution deals with selected pathological and ethological criteria as well as biological performance. The improved freedom of motion for the sows resulted in a smaller percentage of soiled animals. The number of lying downs with the sow lying its rear quarter down opposite the grouped piglets was considerably higher in the activity pens. Piglet mortality from crushing occurred more often in activity pens than in conventional farrowing crates or opening crates.application/pdfengArticle
