The aim of this study was to compare barn-keeping (BK) to pasture-based-keeping (PK) systems in dairy farming. We established two herds which were kept under the same conditions and with an equal agricultural area (AA) on the same experimental farm from 2008 to 2010. The BK herd consisted of 12 Swiss Holstein-Friesian and 12 Brown Swiss cows which were kept in a free-stall barn and fed with a part-mixed ration composed of maize silage, grass silage and protein concentrate. They were allocated 15.8 ha AA [therefore 42.9 % grass silage, 18.3 % maize silage, 8.9 % cereals (energy concentrate), 18.4 % area for protein concentrate, 5.8 % pasture, 5.8 % extensive grassland (hay)].[...] In conclusion, the productivity and the efficiency of the BK herd were higher compared to the PK herd due to the higher energy intake per kg feed and the higher nutrient intake postpartum.
