    Litterless Housing Systems in the Farrowing Area I : Project Overview and Housing Environment
    (2003) Snell, Hinrich; Kamphues, Barbara; Hessel, Engel F.; Van den Weghe, Herman; Lücke, Wolfgang
    In the project presented here, three housing variants (conventional crate stall, opening crate stall, activity pen) for nursing sows featuring identi- cal environmental conditions were compared over a period of several years. In addition, the objective was to study the effects of a temporally and quantitatively limited straw supply. This first contribution provides an overview of the project. In addition, the results of stall climate meas- urements and the evaluation of pen soiling will be presented. The improved freedom of motion for the mother animals did not result in measurable effects on the stall climate. Small quantities of straw did not lead to any increase in the concentration of suspended dust in the stall air. In quantitative terms, the soiling of otherwise clean pen areas in the activity pens due to the increased mobility of the sows was insignificant.

    Litterless Housing Systems in the Farrowing Area II
    (2003) Kamphues, Barbara; Snell, Hinrich; Hessel, Engel F.; Van den Weghe, Herman; Lücke, Wolfgang
    Three housing systems (conventional farrowing crate, opening crate, ac- tivity pen) for nursing sows were compared in the present study. 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.
