The aim of this study was to assess animal welfare in conventional fattening pig systems. Development of means to improve animal welfare shall put the producer in a position to structure the production more in line with consumer requirements. To carry out this assessment the data of 100 fattening pig farms in North-Rhine Westphalia have been analysed. The study comprises of two parts, firstly the collection of operational data and data of housingsystems, and secondly behaviour investigations. In the analysis of the farm data it was found that, particularly in farms with slatted systems important points of the SVHO (1995) were not followed. Deficits were found in space allowance, dimensions of the slatted floors, drinking systems and objects for occupation. Problems apparent in all housing systems were mainly caused by climatic conditions and lighting. In the observational data the most frequent observation was the lying behaviour. This was significantly lower in deep litter systems. The values for the lying behaviour were in line with the figures quoted in the literature for intensively kept pigs. Animals on farms with straw systems, were significantly more active than animals on farms with fully slatted floors, due to the incentives given by the availability of straw. In slatted floor systems the manipulation of penmate and occupational objects were much higher represented in the total behaviour than in straw systems. Abnormal behaviour was found in all housing systems, however only in small amounts. At the end of this study suggestions for ways of improvement were made specific to the relevant husbandry systems, which included housing as well as management factors.
